  • Top two best video cards for older Mac Pros?

    I have some older Mac Pro towers that vary from:
    2.66 GHz Quad Core Intel Xeon
    ..to this:
    2 x 2.93 GHz 6 Core Intel Xeon
    Looking for at least the top two video cards that are tried and tested that would work best with at least Premiere Pro and AME. I just need to narrow down the unwieldy list that can be found here: http://www.adobe.com/products/premiere/tech-specs.html

    Are you adverse to using aftermarket cards that have been converted to work properly in a Mac?  If you aren't, then I'd recommend talking to Dave @ MacVidCards because he can cook you up an nVidia 700-series card that will boot properly in a Mac Pro, run at PCI-E 2.0 speeds, and work wonderfully in Pr/AME.

  • Mac Pro compatibility with HP Designjet Plotter

    Hi All.
    My architectural firm are about to order some new Mac Pro's and a new HP Designjet 500 A1 plotter. I'm currently using a G5 on 10.4.7 and have just noticed that the HP 500 is not listed in the Printer Setup Utility.
    Does anyone know if support for this plotter is available anywhere?
    Thanks.

    AJ -
    We had the same problem with our old Designjet 430. Both OS9 and OSX were completely unsupported by HP. We had to fork out for 3rd party software for OS9 and the Gimp driver for OSX resulted in very poor quality plots.
    I've had a look and there is a HP driver for the 500 for OSX, but for 10.4 it says:
    HP Printers - Mac OS: Print only HP Drivers (non-Postscript) built into Mac OS X v10.4 (Tiger)
    Mac OS X v10.4 Tiger and HP Driversback to top of page
    The latest HP printer driver for this device is built into Tiger for print only functionality and does not require a download or reinstallation of any HP software to print.
    This document applies to raster (non-Postscript) HP Designjet, Deskjet, Business Inkjet, and LaserJet printers.
    In order to best take advantage of the latest HP driver and new Mac OS X v10.4 Tiger features, it is recommended that you delete original HP printer queues from Printer Setup Utility and create a new HP printer queue.
    Tiger - HP printer setup instructions:
    1.Upgrade install from Mac OS X v10.1, 10.2, 10.3 - select 'Reset Printing System" option (from the Printer Setup Utility pull down menu) to delete all previous printer queues. The HP printer queue can also be deleted manually from Printer Setup Utility.
    2.From Printer Setup Utility, click on Add, select connection type (e.g. All, Bonjour, USB, Appletalk) and create new HP printer queue. The Printer Setup Utility is found in the Applications/Utilities folder.
    3.Clean install - If there is a clean install of Tiger, follow step 2 to add a new HP printer queue.
    That has me scratching my head because as I said, the 500 isn't listed in Printer Setup.
    Any ideas?

  • Mac pro 13'' harddisk makes noises when writing and reading data, but Techtool scanning result shows no bad blocks in the disk, that is normal?

    I bought my Mac pro 13 inch, i7 processor and 750G storage 20th November 2012. But I found when copy into or out the Mac, the harddisk makes noises, like bitting something. I thought there are bad blocks in the disk, but the result of Techtool scanning is no bad blocks in disk, and giving a passed conclusion.
    I went the apple store for testing, and the repairmen told me there are two choices available for me:1) replace the harddisk 2) back to the store i bought machine from for a new one. i think that the machine only bought few days, it had better not be disassembled, so i went back for a new one. unfortunately, the new one makes more noises than my old one. i don't know why like apple named brands notebooks have such problems.  did you undergo this experience ?

    All of the HDDs, be they in my MBPs or enclosures are barely audible.  I would say the you deserve no less.  I suggest that you do not leave until you are satisfied with a near silent HDD.
    Why you got two in a row is a puzzle, but then some people beat the odds and win the lottery.  In your case the results are not exactly positive.  All HDDs eventually fail, and some fail sooner than others.  At least you should start with a quiet one.
    Good luck.
    Ciao.

  • Mac Pro & Powerbook data transfer / what about bad blocks

    Hello,
    Well i have Mac Pro and a old Powerbook G4. Both are running OSX (one intel version and the other PPC). the powerbook is booting from an external firewire drive which i have installed OSX (PPC) on. ( mainly because the internal drive of the laptop died).
    So I want to transfer some data from the external drive to my Mac Pro. Is it okay just to shutdown the Powerbook, and connect it & mount it on the Mac Pro as an external drive? (not the actual Powerbook, just the external drive itself...) Will there be complications since it has OSX (PPC) installed? I want to transfer some files of the external to my Mac Pro.
    (...I know another option would be to network them together too.....)
    I am not trying to boot from it...
    another quick question....
    The external drive with OSX (PPC) installed, has had a shady history, it has crashed a few times on me, bad blocks, sometimes a click here and there...it been partioned a few times....etc..
    When I transfer data or files from the bad drive to my good one, could it possibly transfer those bad data blocks to the other hard drive on my Mac Pro, and possibly "infect" it?

    The following may help you:
    A Basic Guide for Migrating to Intel-Macs
    If you are migrating a PowerPC system (G3, G4, or G5) to an Intel-Mac be careful what you migrate. Keep in mind that some items that may get transferred will not work on Intel machines and may end up causing your computer's operating system to malfunction.
    Rosetta supports "software that runs on the PowerPC G3 or G4 processor that are built for Mac OS X". This excludes the items that are not universal binaries or simply will not work in Rosetta:
    Classic Environment, and subsequently any Mac OS 9 or earlier applications
    Screensavers written for the PowerPC
    System Preference add-ons
    All Unsanity Haxies
    Browser and other plug-ins
    Contextual Menu Items
    Applications which specifically require the PowerPC G5
    Kernel extensions
    Java applications with JNI (PowerPC) libraries
    See also What Can Be Translated by Rosetta.
    In addition to the above you could also have problems with migrated cache files and/or cache files containing code that is incompatible.
    If you migrate a user folder that contains any of these items, you may find that your Intel-Mac is malfunctioning. It would be wise to take care when migrating your systems from a PowerPC platform to an Intel-Mac platform to assure that you do not migrate these incompatible items.
    If you have problems with applications not working, then completely uninstall said application and reinstall it from scratch. Take great care with Java applications and Java-based Peer-to-Peer applications. Many Java apps will not work on Intel-Macs as they are currently compiled. As of this time Limewire, Cabos, and Acquisition are available as universal binaries. Do not install browser plug-ins such as Flash or Shockwave from downloaded installers unless they are universal binaries. The version of OS X installed on your Intel-Mac comes with special compatible versions of Flash and Shockwave plug-ins for use with your browser.
    The same problem will exist for any hardware drivers such as mouse software unless the drivers have been compiled as universal binaries. For third-party mice the current choices are USB Overdrive or SteerMouse. Contact the developer or manufacturer of your third-party mouse software to find out when a universal binary version will be available.
    Also be careful with some backup utilities and third-party disk repair utilities. Disk Warrior (does not work), TechTool Pro (pre-4.5.1 versions do not work), SuperDuper (newest release works), and Drive Genius (untested) may not work properly on Intel-Macs. The same caution may apply to the many "maintenance" utilities that have not yet been converted to universal binaries.
    Before migrating or installing software on your Intel-Mac check MacFixit's Rosetta Compatibility Index.
    Additional links that will be helpful to new Intel-Mac users:

    Transferring data with Setup Assistant - Migration Assistant FAQ
    Because Migration Assistant isn't the ideal way to migrate from PowerPC to Intel Macs, using Target Disk Mode or copying the critical contents to CD and DVD or an external hard drive will work better when moving from PowerPC to Intel Macs.
    Basically the instructions you should follow are:
    1. Backup your data first. This is vitally important in case you make a mistake or there's some other problem.
    2. Connect a Firewire cable between your old Mac and your new Intel Mac.
    3. Startup your old Mac in Target Disk Mode.
    4. Startup your new Mac for the first time, go through the setup and registration screens, but do NOT migrate data over. Get to your desktop on the new Mac without migrating any new data over.
    4. Copy the following items from your old Mac to the new Mac:
    In your /Home/ folder: Documents, Movies, Music, Pictures, and Sites folders.
    In your /Home/Library/ folder:
    /Home/Library/Application Support/AddressBook (copy the whole folder)
    /Home/Library/Application Support/iCal (copy the whole folder)
    Also in /Home/Library/Application Support (copy whatever else you need including folders for any third-party applications)
    /Home/Library/Keychains (copy the whole folder)
    /Home/Library/Mail (copy the whole folder)
    /Home/Library/Preferences/com.apple.mail.plist (* This is a very important file which contains all email account settings and general mail preferences.)
    /Home/Library/Preferences/ copy any preferences needed for third-party applications
    /Home /Library/iTunes (copy the whole folder)
    /Home /Library/Safari (copy the whole folder)
    If you want cookies:
    /Home/Library/Cookies/Cookies.plist
    /Home/Library/Application Support/WebFoundation/HTTPCookies.plist
    For Entourage users:
    Entourage is in /Home/Documents/Microsoft User Data
    Also in /Home/Library/Preferences/Microsoft
    Credit goes to another forum user for this information.
    If you need to transfer data for other applications please ask the vendor or ask in the Discussions where specific applications store their data.
    5. Once you have transferred what you need restart the new Mac and test to make sure the contents are there for each of the applications.

  • Never owned a Mac, thinking of buying a Mac Pro, could use some advice...

    Hey guys,
    I know this was a lot to read, but I sincerely hope someone will take the time to answer my questions:
    As the title of my post implies I've never owned a Mac in my life. I've always built my own desktops and usually gone to HP or Dell for my laptops. I'm approaching that time again where my custom-built desktop is looking outdated and I'm getting the upgrade itch. I'm looking at all the parts I need to order to build a computer and I can't help but think I'm older now with a full-time job and a one year old daughter in the house. Do I really want to go through the hassle of building a desktop from scratch again? Not really. So I started evaluating things a bit. As I get older I’m really just getting sick and tired of Microsoft’s antics (Vista was a huge disappointment for me) so I decided this could be the year for me to take the Mac plunge.
    Now I’m an IT guy, so I have a pretty atypical setup at home. I’m currently running both Windows and Linux on all my computers. Rather than dual boot or use virtualization software I have a pretty intricate system in which I use a product called Acronis Trueimage to experiment with operating systems. What I do is perform a a clean install on an operating system, tweak it as needed for security and to use resources on my LAN than back up the customized OS install to a server a an image file. I have pre-built images for XP, Vista, Ubuntu and OpenSuSE that I can roll out to one of my machines in an average of 15 minutes whenever I get the urge to switch operating systems. I also serve all my data off a NAS box, so since data and OS are kept separate on the network I don’t have to worry about erasing something when I swap between Linux and Windows (as loading an image literally destroys the previous OS install).
    So you can see I’m pretty highly specialized. I even have things down to the point to where I have custom images for specific purposes. For instance I have one XP image customized for development, one XP image customized for gaming, etc. Naturally if I got the Mac Pro I’d like to have the freedom to create a similar set of custom OS deployment images (Windows, Linux and OSX) for it as well. In researching the Mac Pro I have some concerns my current system might not work if I go that route. Am I correct in assuming that in order to run an alternative operating system on a Mac I’ll have to run boot camp or something like it? Or upon unboxing my Mac and tweaking Leopard will I be able to use disk imaging software to make a backup image of my preinstalled Leopard hard drive and then do a clean install of Windows XP or Ubuntu and set it up to function like a PC? I guess I’m asking if it’s possible (now that Macs are Intel-based) to run Windows or Linux exclusively on the Mac hardware?
    Also I have some concerns about the proprietary nature of the Mac platform. From what I can gather in my research it seems the hardware is pretty locked in. One area that has me really concerned is gaming. I pretty much use Ubuntu exclusively at home for productivity and web surfing. However I still like to load that XP image every now and then to play some games on the LAN with my buddies. I’m not a fan of virtualizing for gaming because of the obvious performance hit you take, so I’d have to be able to run Windows XP free and clear. Also I checked Nvidia’s site and I see no OSX drivers listed there for their cards. Under the Windows platform they are always releasing driver updates to squeeze more game performance out of your card. What if I want to upgrade my video card? How do drivers work on OSX? Does Apple just integrate drivers for just a few specific video cards into the OS? Will I be stuck only able to pick from a handful of video cards approved by Apple?
    Thanks in advance to anyone who can offer advice!

    Hi Zeus
    I may be able to answer some of your questions. And sorry in advance if this sounds like yet another of those "religious conversion" stories
    I'm a software developer/architect, mostly doing Microsoft .NET/C#/Web Services coding. I'd been a loyal Microsoft guy since I started on the original IBM PC back in the 80's. Like a lot of people (or so it seems) I just got fed up with Microsoft's high-handed and self-important ways. More importantly, the company always seemed to be lagging behind technically. Looking at beta versions of Vista did not bode well for the future - it just seemed awful. When Vista came out it it was the last straw - I just could not get enthusiastic about this bloated, slow, mess of an operating system. I really hated it. Still do. Even with a top-spec machine, Vista didn't run in the snappy, responsive way it I thought it should. Nothing seemed well thought out.. yuck!
    Then, by chance, I was staying for a few days with somebody who had a Mac. Now, for years and years I not even considered Macs as remotely serious machines. My only experience of them was in the late 80's when somebody at work had one. He took delight in pushing a floppy disc into the machine so that it would respond "Ah, it's so big!". Great, just a toy. Not for serious programming work. So, encountering Mac OS X Tiger on my friend's iMac was something of a shock. It was so responsive, clean and elegant. When you turned it on it only took about 30 seconds or so for the thing to be ready for use, etc, etc.
    Long story short, I bought an iMac, then a newer, bigger, faster iMac, then a MacBook Pro and now I have a Mac Pro. I still have to work with Windows to do my .NET-related day job. But 95% of the time I work on the Mac using various VMWare virtual machines. I can switch between Windows Server 2008, Windows Server 2003 and Windows XP in a few seconds and still be working in a Mac environment. And the performance of running Windows inside VMWare is even better than on my dedicated top-spec Windows laptop! I have a selection of virtual machines to choose from and, because these virtual machines are just files, I can back them up, revert to saved copies, etc. I've tried Bootcamp but it's much less convenient and performance inside the virtual machines is never an issue (although I don't do any gaming). So, you could keep virtual machines on your NAS box or local Mac hard drive.
    With regard to graphics drives, etc. I've never had any problems whatever in this respect. For example, when I installed Windows XP on VMWare it automatically recognised all my hardware (including some obscure audio interfaces, USB-based MIDI interfaces, etc.) and made it available. I must admit that when I was new to the Mac I expected to have driver issues, but never have had... So, my guess is that you'll be able to run all your Windows and Linux distros on the Mac without too many problems.
    You mention Apple's hardware as being "locked-in". I don't think that's the case. Certainly the consumer Mac models like the iMac can't be upgraded (by you or me) internally, expect for memory. The Mac Pro though is very easy to upgrade - though there may be some limitations with regard graphics cards.
    Re your questions about graphics card drivers. Yes, these come with OS X in just the same as as with Windows. Because I've also used the card that comes "with the box" this has not been an issue for me. However, unless you get a Mac Pro you can't swap-in your existing graphics card. And even then I think you may find restrictions. However, other, more knowledgeable Mac users on this forum may have other thoughts.
    Overall though, the experience of using the Mac in terms of software is very much the reverse of Windows - the OS is very open and well documented. It really is an IT person's dream machine - so much to fiddle around with (particularly if you know anything about Unix!). Unlike Microsoft who charge a FORTUNE for their development tools, Apple give them to you for free. And very good they are too!
    Finally, one bit of advice. If you are considering buying a new Mac, join the Apple Developer Connection scheme as a Select member. It'll cost you around $400 to join but they give you a hardware discount for Apple-store purchased items that will save you a ton of $$$'s - absolutely definitely worth doing.
    Hope this helps (and good luck)!

  • Ive got a Mac Pro bought seconf hand, It doesn't allow me to update as the username is blocked to the previous owner, it appears off and can't change it, the box goes directly to password. I have changed the computer username and password but the problem

    Ive got a Mac Pro 2010, bought second hand through eBay. When it comes to update the software, the username is blocked to the previous owner. It appears off and the box goes directly to password. I have tried to reset then to log in in apple store with my login but didn't help. I would appreciate any tips to sort it out
    Thanks fellas

    That machine did not ship with Mountain Lion (Mac OS X 10.8), so that means the copy of Mountain Lion on the machine was purchased by the former owner and is non-transferable. It is permanently linked to his/her Apple ID, so you cannot update or reinstall it.
    What you need to do (which the seller should have done for you) is reinstall the original system that that machine came with. I believe that would be Snow Leopard (Mac OS X 10.6). What you need to do is reinstall that system from the original disks. If the seller did not provide those disks, you can call Apple and get them replaced for a small shipping and handling fee.

  • I have some questions regarding setting up a software RAID 0 on a Mac Pro

    I have some questions regarding setting up a software RAID 0 on a Mac pro (early 2009).
    These questions might seem stupid to many of you, but, as my last, in fact my one and only, computer before the Mac Pro was a IICX/4/80 running System 7.5, I am a complete novice regarding this particular matter.
    A few days ago I installed a WD3000HLFS VelociRaptor 300GB in bay 1, and moved the original 640GB HD to bay 2. I now have 2 bootable internal drives, and currently I am using the VR300 as my startup disk. Instead of cloning from the original drive, I have reinstalled the Mac OS, and all my applications & software onto the VR300. Everything is backed up onto a WD SE II 2TB external drive, using Time Machine. The original 640GB has an eDrive partition, which was created some time ago using TechTool Pro 5.
    The system will be used primarily for photo editing, digital imaging, and to produce colour prints up to A2 size. Some of the image files, from scanned imports of film negatives & transparencies, will be 40MB or larger. Next year I hope to buy a high resolution full frame digital SLR, which will also generate large files.
    Currently I am using Apple's bundled iPhoto, Aperture 2, Photoshop Elements 8, Silverfast Ai, ColorMunki Photo, EZcolor and other applications/software. I will also be using Photoshop CS5, when it becomes available, and I will probably change over to Lightroom 3, which is currently in Beta, because I have had problems with Aperture, which, until recent upgrades (HD, RAM & graphics card) to my system, would not even load images for print. All I had was a blank preview page, and a constant, frozen "loading" message - the symbol underneath remained static, instead of revolving!
    It is now possible to print images from within Aperture 2, but I am not happy with the colour fidelity, whereas it is possible to produce excellent, natural colour prints using its "minnow" sibling, iPhoto!
    My intention is to buy another 3 VR300s to form a 4 drive Raid 0 array for optimum performance, and to store the original 640GB drive as an emergency bootable back-up. I would have ordered the additional VR300s already, but for the fact that there appears to have been a run on them, and currently they are out of stock at all, but the more expensive, UK resellers.
    I should be most grateful to receive advice regarding the following questions:
    QUESTION 1:
    I have had a look at the RAID setting up facility in Disk Utility and it states: "To create a RAID set, drag disks or partitions into the list below".
    If I install another 3 VR300s, can I drag all 4 of them into the "list below" box, without any risk of losing everything I have already installed on the existing VR300?
    Or would I have to reinstall the OS, applications and software again?
    I mention this, because one of the applications, Personal accountz, has a label on its CD wallet stating that the Licence Key can only be used once, and I have already used it when I installed it on the existing VR300.
    QUESTION 2:
    I understand that the failure of just one drive will result in all the data in a Raid 0 array being lost.
    Does this mean that I would not be able to boot up from the 4 drive array in that scenario?
    Even so, it would be worth the risk to gain the optimum performance provide by Raid 0 over the other RAID setup options, and, in addition to the SE II, I will probably back up all my image files onto a portable drive as an additional precaution.
    QUESTION 3:
    Is it possible to create an eDrive partition, using TechTool Pro 5, on the VR300 in bay !?
    Or would this not be of any use anyway, in the event of a single drive failure?
    QUESTION 4:
    Would there be a significant increase in performance using a 4 x VR300 drive RAID 0 array, compared to only 2 or 3 drives?
    QUESTION 5:
    If I used a 3 x VR300 RAID 0 array, and installed either a cloned VR300 or the original 640GB HD in bay 4, and I left the Startup Disk in System Preferences unlocked, would the system boot up automatically from the 4th. drive in the event of a single drive failure in the 3 drive RAID 0 array which had been selected for startup?
    Apologies if these seem stupid questions, but I am trying to determine the best option without foregoing optimum performance.

    Well said.
    Steps to set up RAID
    Setting up a RAID array in Mac OS X is part of the installation process. This procedure assumes that you have already installed Mac OS 10.1 and the hard drive subsystem (two hard drives and a PCI controller card, for example) that RAID will be implemented on. Follow these steps:
    1. Open Disk Utility (/Applications/Utilities).
    2. When the disks appear in the pane on the left, select the disks you wish to be in the array and drag them to the disk panel.
    3. Choose Stripe or Mirror from the RAID Scheme pop-up menu.
    4. Name the RAID set.
    5. Choose a volume format. The size of the array will be automatically determined based on what you selected.
    6. Click Create.
    Recovering from a hard drive failure on a mirrored array
    1. Open Disk Utility in (/Applications/Utilities).
    2. Click the RAID tab. If an issue has occurred, a dialog box will appear that describes it.
    3. If an issue with the disk is indicated, click Rebuild.
    4. If Rebuild does not work, shut down the computer and replace the damaged hard disk.
    5. Repeat steps 1 and 2.
    6. Drag the icon of the new disk on top of that of the removed disk.
    7. Click Rebuild.
    http://support.apple.com/kb/HT2559
    Drive A + B = VOLUME ONE
    Drive C + D = VOLUME TWO
    What you put on those volumes is of course up to you and easy to do.
    A system really only needs to be backed up "as needed" like before you add or update or install anything.
    /Users can be backed up hourly, daily, weekly schedule
    Media files as needed.
    Things that hurt performance:
    Page outs
    Spotlight - disable this for boot drive and 'scratch'
    SCRATCH: Temporary space; erased between projects and steps.
    http://en.wikipedia.org/wiki/StandardRAIDlevels
    (normally I'd link to Wikipedia but I can't load right now)
    Disk drives are the slowest component, so tackling that has always made sense. Easy way to make a difference. More RAM only if it will be of value and used. Same with more/faster processors, or graphic card.

  • Mac Pro crashing on shutdown (and some other things)

    The following behavior began about 4 or 5 days ago...
    Mac Pro crashes/freezes every time I shutdown (or Restart).  Some process seems to be not quitting on shutdown - the screen goes blue and I get the spinning beachball. It'll just hang like that indefinitely.  To get it to shut down, I have to hold the power button for several seconds.  After starting up again, the machine *mostly* runs fine, but there are some apps/services that either just don't do anything, or causes the Mac to hang, or get into a funk state. These other things that seem to destabilize it include:
    Apple menu > About this Mac: nothing happens (no dialog)
    iTunes: dock icon just bounces, iTunes never launches
    System Prefs > Accounts > Login items: System Prefs hangs. Force quit allows Prefs to open again.
    Some apps/services also cause things to hang:
    Activity Monitor: quitting some processes causes Actvity Monitor to freeze
    Clicking SOHO Notes (tab alonmg the edge of the monitor) results in spinning beachball
    Rolling over Linotype FontExplorer in the Dock causes the Dock to freeze, FontExporer never opens
    There are probably other things that would make it hang, I have not gone looking for them all
    System details:
    Mac Pro 4,1 .66 ghz, 8 GB RAM
    Mac OSX 10.6.8
    Dual monitors, two internal hard drives (internal; drive A, internal drive B), multiple external FW hard drives attached
    I have already done the following:
    Disk Utility: Verified and Repaired Disk Permissions
    Disk Utility: Verified Disk, Repaired Disk - this found errors, and suggested reformat/reinstall
    I have already booted off internal drive B and ran Disk Utility, then restarted and booted off internal drive A again.  No difference.
    I have Time Machine backups on an external 1 TB FW drive.
    Late last night, I restarted, inserted my original Snow Leopard DVD, launched the MacOSX installer. Recovered a prior system by choosing Utilities > Restore System From Backup, selected a Time Machine backup a few days old (a day or two prior to the problem begining) on the external 1 TB FW drive, and initiated the restore.  The estimated restore time was about 5 hours, so I went to bed and let it run.  Got up early, and checked: it said the Restore operation was successful.  I was relieved.  But the same conditions continued - launching or rolling over the items listed above cause the same freeze/crash/hangs.  Hangs on shutdown, only way to kill things is the power button.  So now I'm disappointed.
    I do have multiple backups of my data files across the external hard drives, but this is a large machine with a lot of stuff on it, and I'd really like to recover things wholesale, rather than having to reconstruct accounts and other things.  Before I go to bed tonight, I'm going to take another shot at recovering the system from a Time Machine backup - this time, I'll pick a backup that's from a full week before the problems started (the idea being that maybe the backup I picked last time was not far enough back from whatever incident caused all this).
    If the week-old Time Machine backup works, great. But if not...any suggestions?
    Additional data points...
    Nothing new was installed or updated (as far as I know, and I generally pay attention) in the days prior to the problem.
    The last thing I recall doing on the computer before the problem began, was burning a DVD (using Toast) - something I do all the time. After that operation, I tried to shut down, and it froze.
    The primary internal hard drive partition (internal drive A) seems to be the only one that's having trouble: if I reboot off of internal drive B, the problems do NOT occur - no hang on quit, etc.
    That suggests it's not a hardware problem (logic board, etc.) but is something about the System on drive A.
    It *could* be bad sectors on drive A - but I have some questions about that...
    When I did the full system recovery via the MacOS installer (pulling the old system from Time machine), does the destination drive get reformatted? I don't recall being asked the usual partition/formatting questions.
    When the installer does a system restore, does it do any integrity checking on the target drive, or does it just blindly lay down bits?
    Does this "freeze on shutdown" (and related behaviors) sound familiar?
    Any tips/suggestions to fix this?
    Thanks in advance.

    More info and a question...
    Did another full restore (from a Time machine backup on an external drive) last night - picked a backup from from 10 days ago, long before things became problematic.  Still having the same issues.
    So, I'm thinking the next thing to try is a low-level reformat of the internal drive(s) and then restore again.  I have a couple questions about the finer points of that...
    I'm following the instructions in this KB document: Mac OS X 10.6: Recovering your entire system.
    Inserting my original Snow Leopard DVD, launching the MacOS installer, restarting, in the installer choosing Restore System from Backup.  It appears that there is no re-formatting of the target drive in this case - it just over-writes.
    My questions...
    The contents of the target drive are going to get wiped and overwritten anyway. Do I have anything to lose/to risk by reformatting FIRST (using Disk Utility), then booting off the install DVD and restoring then?
    My 1 TB internal drive is partitioned into the primary 750 GB partition (which is the problematic one) and a secondary 250 GB partition (which boots and runs fine).  The secondary partition has some data I would prefer not to lose.  I assume that if want to do a full reformat of the internal drive, that means the whole drive - both partitions - will be wiped (that is, I cant reformat just one partition on a single physical drive without reformatting the second partition).  Correct?
    I suppose I can back up the data that resides on the second partition to an additional external drive (I have extras) if needed - not a huge deal.
    Do my new partition sizes need to exactly match the sizes of the original partitions?  Neither is completely full, but I want to make sure that I will be able to restore the system and contents of the primary partition even if the new partition size is not bit-by-bit the exact same size as the old partition (I assume the new partition size just needs to be large enough to hold the backup - correct?).
    So....I'm looking at the following sequence:
    Back up the data I want off the secondary partition to an external drive
    Boot off the Snow Leopard install DVD
    Run Disk Utility and reformat (fully erase) the internall 1 TB drive
    Partition that 1 TB internal drive to (more or less) the two previous (about) 750 GB + 250 GB partitions
    Restore a recent Time Machine backup (from an external FW drive) to partition #1
    Reasonable plan?  Anything I'm missing here?  Any other steps I should take?
    Thanks for any help.

    If you bought them on your iPad then you will need to connect your iPad to your computer's iTunes and do File > Devices > Transfer Purchases to copy them over to the Tones part of your computer's iTunes library and you can then sync them to your iPhone - ringtones are a one-time only download, so you won't be able to redownload them directly on your phone.

  • MAC PRO (Early 2008) RAID CARD ISSUE - SYSTEM FREEZEHello (hopefully someone can shed some light on my issue)  I own as above a MAC PRO (Early 2008) this has a RAID card installed along with two 15k.7 cheetah hdd (320gb) and a spare drive, (which i m

    Hello (hopefully someone can shed some light on my issue)
    I own as above a MAC PRO (Early 2008) this has a RAID card installed along with two 15k.7 cheetah hdd (320gb) and a spare drive, (which i made a regular drive)
    a while ago i had to replace the RAID card battery, so i did this, over a year later the same thing happened again, but as previous just left it and the system seemed fine for ages, until last night i was working in PHOTOSHOP and everything just froze and the screen kind of appeared GREEN, could not do a single thing. So restarted the mac, this time grey screen for ages and a message appeared, (macs version of blue screen) (see attached).
    I restarted the machine and this time a flashing question mark folder!
    could not do a thing.
    so i found my copy of snow leopard and got the computer to run this and at least launch the DISK UTILITY and (Interestingly in the drop down menu RAID UTILITY was also in the menu) but it did not matter which utility i used the (RAID or DISK) neither could see any of drives, just the dvd drive.
    so looked around on you tube and various forums and discovered if i take out the RAID CARD and re-plug the main lead from the RAID card back in to the LOGIC BOARD I would be reverting the MAC to a normal regular non-RAID computer.
    After performing this HARDWARE task and inserting all three HDD, and running the DISK utility from the drop down menu via the SNOW LEOPARD disc.
    (interestingly since the RAID card had been removed the RAID UTILITY  from the drop down menu no longer appeared). running disk utility I can now only see the regular (spare) hdd and DVD Drive, but the two RAID HDD , again, still do not show up DISK UTILITY?
    O.K. so i could chuck out the RAID card (AND RAID HDD) and just go with a regular set-up, and run a back restore from Time Machine on a NEW hdd purchased.
    but what is wrong with the RAID, is the card at fault or are both HDD used for the RAID knackered? can i perform any tests, to see whats what?
    thanks for your help in advanced.

    hello people, the issue was in fact the GRAPHICS card nothing to do with the HDD or RAID system ( although this did cause issues with the RAID system it basically lost its way) below is my replay to another similar  problem some one else had!
    working in photoshop and then everything stopped working and the lot froze! only option was to force shutdown (via button).
    and try to restart, hoping all was fine, this was not the case :-(
    I had the added issue of the RAID card system, that i have, this was confused to say the lease and would not behave or work, causing the start up to hang.
    so i thought the HDD must be bust and the root cause. ( but soon learnt it was not the cause )
    ...bought a new HDD removed the RAID card and replugged the cable from RAID card into LOGIC board, ( making the computer act like any normal non-RAID system). I managed to install the OSX, using the snow leopard disk way. once the mac was running, i started to notice the screen would flicker and started to see 'artefacts'. so i started to reveal my symptoms to the web and forums and soon discovered that my graphics card could be the issue all along?.
    (nvidia geforce 8800gt 2x dvi).
    I read up on that a fix, could be either A. reply the thermal paste, as the card could be over heating or B. stick the card in the oven trick.
    Tried option A. first and nothing still issues, so last night took the plunge carried out option B. and ta da it worked! i even managed to run
    from my new HDD my lasted install OS X, absolutely fine. I then thought, maybe i could repair my RAID so replugged all the HARDWARD back in and
    carried out a disk repair and disk permissions on drives( took a small amount of time), via the SNOW LEOPARD disc - (Disk utilities) and this worked and now have my system working as it was just over 6 days ago.
    what was the cost to get this?  bought a new hdd so 40.00gbp and thermal paste and cleaner kit ( your still need to do this ) search video card trick on you tube.
    and renew thermal paste, approx 15.00gbp, technically i don't need the new HDD, but it was all part of the trial and error way i went. ( i do have extra storage as a result!)"

  • I bought a new Mac Pro from an Apple store, it was sold as factory sealed, but it's reconditioned - it has some strangers entire photo,library from 2003 to 2011 in the trash bin.

    . I bought a new Mac Pro from an Apple store 2 days ok, it was sold as factory sealed, but it's reconditioned - it has some strangers entire photo,library from 2003 to 2011 in the trash bin.
    I was bought a Mac book pro as a birthday gift from the Apple Store in Leicester, after completing the initial set up procedure, I noticed that  the trash bin was full of some one's entire photo collection from 2003 to 2011.
    This is entirely unacceptable for Apple: How long have Apple been fobbing of consumers who believe they were genuinely purchasing a 'new' Mac book?
    How is it that I have someones entire photo collection on my 'branch new Mac Book Pro' - these photos included wedding photo's, birthday celebrations, family celebrations and children. Its a serious breach of data protection, it's an invasion of some poor persons privacy and private photo collection. What concerns me the most, is what could have happened if those photo's had fallen into the wrong hands. We managed to trace, locate and contact the person who the photo's belong to within 10 mins using information taken from their wedding album.
    Understandably these people are also very distressed that their personal photos are on my brand new Mac Book pro.
    I would like details of who to contact in regards this incident.

  • Mac Pro RAID block size recommendations for working with audio in Logic Pro

    I have recently ordered a Mac Pro and plan to do a RAID configuration across 3 HDD's
    The RAID type i am going to do is a RAID 0 striped.
    The computer is going to be used primarily for audio post production and working with 20+ 24-Bit audio files at any one time within a Logic project.
    I want to know what is the best block size i should use when configuring the RAID.
    I understand that using a higher block size is best for working with large files but do i need to do this in my case or will the default 32k block size be enough?
    Thanks in advance

    Use 64k. Things like databases like having 32k blocks because of all the small files. Audio files are pretty small even at 24-bit 192KHz. Go to 128k if all you are doing is streaming and no samples. But 20+ 24-bit is really not too large anyway considering most modern HDD's can stream 100MB/s off one spindle. You'll probably be fine regardless of the block size you choose. But most audio pro's choose 64k.

  • Mac Pro DVD drive won't load some software discs

    I just bought two sets of Photoshop Elements, and my 2007 Mac Pro failed to recognize all six DVDs. I'm realizing I've had this problem with a few software discs in recent years, including some Final Cut Studio install discs. CDs and regular DVDs work fine - just some software DVDs are eventually ejected by the computer without showing up on the desktop. I have tried cleaning the drive with a disc cleaner.
    My way around it has been to put these discs in my PC, make a copy, and then these copies load fine in my Mac. But it's a nuisance, and my PC won't be around forever.
    Can anyone suggest what the problem might be? Or a decent external drive (Blu-ray?) that I might want to replace it with?
    Thanks.

    I'll try that tomorrow. Thinking it could also be:
    1)  The PRAMM battery. found info on that they can wear out close to 5 years. This MAC PRO is close to that now.  And I use a lot of power on it.
    2) MAC PRO is plugged into a  SURGE PROTECTOR, instead of right into the wall outlet.
    3) Been doing a lot of FORCE QUITS and HARD BOOT -- unplugging it directly when it wouldn't shut down soon enough --  lately this past year.
    I just assumed that this MAC PRO with the XEON QUAD CORE etc., was a heavy duty enough NLE,
    that i wouldn't have these problems. It's not fully loaded with all the chips it can carry...and I don't have near enough external terabyte hard drives for storing video and audio files to edit. I've been storing wayyy too much
    on the internal hard dives and just have to stop that.
    I noticed these past few days that much of the LETTERING for hard drive icons and folders' titles
    were starting to look in OVERLAPPING of the lettering. That was my first hint that  something was up.

    Advisable is irrelevant...  It is not possible.  There has not been a version of IE for Mac for a long time.  You will have to load Windows on your Mac in order to run IE, or try making your browser mimic IE.  (In Safari, go to Safari -> Preferences, click the Advanced tab and check the box to show the Develop menu.  Then, in that menu, choose User Agent -> Internet Explorer x.0.)  Note that doing that will not work if the site relies on some weird non-standard feature of IE that no other browser on the planet has.
