Should I upgrade to Lion? Have Mac Pro, 2.66Ghz, Core i7, 4GB memory, S-Leopard, purchased 11-2010.

Reading alot of comments on problems running Office 2011, Adobe CS5, Parallels etc. My system operates flawlessly - I'd like to migrate to LION but don't want to create a mess. I've certainly read alot of applause for Lion but haven't seen anyone list the above software as part of their install. I'd expect there are quite a few users running the same software - just need some testimonial to build my confidence that this is the right move. Any comments will be greatly appreciated.
Thanks!

Which raises the question of why would you want to upgrade? Lion is largely cosmetic, and a lot of those cosmetic differences are not pretty
- removal of coloured icons in finder sidebar, making navigation more difficult
- no scroll bar arrows making navigation more difficult (essential if you need fine control of scrollling to move around in design progs like Illustrator/ Quark),
- autosave and versions, making everything more difficult through hideous beach balling on large photoimage files in preview or keynote if you make multiple and rapid minor changes
- dodgy compatibility with some versions of photoshop
- less control over where to keep your folder (apps have to be assiged to the app folder)
- less control over what information remains on your hard disk hidden from you (including versions of your personal files).
- if you use magic trackpad on your MP, you also loose the 4-finger swipe 'app switcher' gesture
On top of all these 'features' you get given:
- mission control, which is less configurable than spaces
- launchpad, which is effectively the same as having 'stacks' and 'grid' options set on your app folder in the dock, only lunchpad takes over your whole screen and is harder to navigate.
Now, that's all IMHO opinion, of course. As someone further up in this thread advised, whatever you do use Carbon Copy Cloner or SuperDuper to clone your current installation. If all is to your liking, you can always use that disk as a regular backup drive. If all is not, the way back to your flawless system is just a five-minute reboot away.

Upgrade mountain lion to mac pro 2007

Have older Mac Pro, early 2007. Can I uprade to Mountain LIon . The online requirement says 2008 or later

If you are willing to endure the crushing complexity of it, there is a Hackintosh solution that allows the loading of EFI-64 work-alike software in RAM (rather than in firmware). This would allow the loading and running of 10.8 on your "too-old" Mac if this is exceptionally important to you.
• This solution may require additional RAM, which is quite expensive for these older Macs.
• If you have serious problems, there is no support available for such a set-up.

Since upgrade to lion on Mac pro the atv2 connection is extremely slow

I upgraded my macro to lion and since then it takes 3 min to pull up the library and times out when trying to down load the show. It worked fine under snow leopard. I have removed and redone the home sharing on both ATV2 and macro still have the same issues.

I have some comments and a suggestion:
Have you tried your setup with a SD/CF combo card reader (like the Lexar or Kingston FCR-H63)? Does the card appear on the desktop when first plugged in?
Did you need to fool around with any kind of power issues in installing this card in the x4 PCIe slot of the MacPro?
Suggestion. Have you tried one of the fixed in this article to cure the BT issues in MacPro 3,1?
Good luck.

I have Mac Pro 2007, which have no bluetooth hardware. What should I do to use Apple wireless keyboard and magic mouse??? Can 'third party's internal bluetooth card' be used for this purpose? Help please...

You can find the Apple Bluetooth card on eBay for as little ten dollars (says its for the 2008 model Mac Pro, not sure about the 2007).
http://www.ebay.com/itm/Bluetooth-Board-iMac-and-Mac-Pro-922-8233-922-8233-/1208 49278570
Here is a link to a full explanation of the card and how to install it. Part numbers may differ a bit as that is an old article and newer models have come out.
http://www.xlr8yourmac.com/systems/Mac_Pro/Bluetooth_MacPro_install/Bluetooth_Ma cPro_install.html
Just make sure that the part will work in your model Mac Pro. To that end, you may be better off avoiding eBay and going to a parts reseller. There are even third party cards that use the internal Apple bluetooth slot.
http://fastmac.com/bluetooth.php
In theory, using a USB or PCI card will work at login so long as it is recognized by Apples drivers. You say you need to launch an application to use your current USB Bluetooth dongle? If it is not controlled by the Bluetooth icon in the menu bar then it must be using a third party driver of some sort. Unfortunately, I don't know off hand which USB and PCI cards are supported.

I have macbook pro running Intel Core 2 Duo if I upgrade to Lion OS Xv10.7 will my macbook run slower?

I have macbook pro running Intel Core 2 Duo if I upgrade to Lion OS Xv10.7 will my macbook run slower?

I have a 13" MBP with the Core 2 Duo processor. I do have 8 GB of memory, needed because I need to run Windows in a virtual machine (Fusion) to access client web sites that require ActiveX controls. The Windows VM environment locks up 3 GB of the memory.
I did all the maintenance steps in disk utility on the harddrive before upgrade, double checked compatability with all applications and drivers and made sure that I had a drive clone in addition to my Time Capsule backup.
The only thing that didn't work on Lion was my RingCentral VOIP client, and that was expected from my research.
The upgrade went smooth and I really haven't noticed much speed difference.

HT1338 Can I upgrade my Intel Xeon MAC PRO running OS X 10.4.11 to 10.5.8?

Can I upgrade my Intel Xeon MAC PRO running OS X 10.4.11 to 10.5.8?

Yes. You can actually upgrade it all the way to Lion should you so wish, although you would need to first purchase and install Snow Leopard 10.6.8.
I would skip Leopard as it's more expensive and obsolete. You can purchase a Snow Leopard DVD at any Apple retailer - $29.00. You can update it by downloading Mac OS X 10.6.8 Update Combo v1.1. The use the App Store to purchase and download Lion should you choose to do so - $30.00.
I would consider expanding your RAM to at least 4 GBs or more especially if you decide to upgrade to Lion. Before upgrading see the following:
How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current OS X Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s).

If you have more than one user account, these instructions must be carried out as an administrator.
Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
Step 1
Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left. If you don't see that menu, select
View ▹ Show Log List
from the menu bar.
Enter "BOOT_TIME" (without the quotes) in the search box. Note the timestamps of those log messages, which refer to the times when the system was booted. Now clear the search box and scroll back in the log to the last boot time after you had the problem. Select the messages logged before the boot, while the system was unresponsive or was failing to shut down. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message (command-V). Please include the BOOT_TIME message at the end of the log extract.
If there are runs of repeated messages, post only one example of each. Don’t post many repetitions of the same message.
When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.
Please do not indiscriminately dump thousands of lines from the log into this discussion.
Important: Some private information, such as your name, may appear in the log. Anonymize before posting.
Step 2
Still in Console, look under System Diagnostic Reports for crash or panic logs, and post the entire contents of the most recent one, if any. In the interest of privacy, I suggest you edit out the “Anonymous UUID,” a long string of letters, numbers, and dashes in the header of the report, if present (it may not be.) Please don’t post any other kind of report — it will be very long and not helpful.

Advice on upgrading to SSD for Mac Pro (optimized for AfterEffects & Photoshop)

Hello,
I'm an animator (I use AfterEffects CS5, but will be upgrading to CC soon) and I'm going to start work on a new AE project in a few months for an animated film that will be very demanding (lots of different shots -- meaning multiple projects, all of which will also incorporate large HD stock footage elements as well as multiple layers of art created in Photoshop).
So I'm looking to upgrade my current desktop Mac Pro (a 2010 2x2.66GHz 6-Core Intel Xeon) with SSD drives (and possibly a new graphics card) in order to speed up my system and optimize it for both AfterEffects and Photoshop. (In the past I've created projects using external 7200 RPM hard drives connected via eSATA). I've also decided, for now, not to purchase the new Mac Pro, but rather try and make a smaller investment to speed up my current system.
I'd love any advice that pro users would have that have made similiar upgrades, both in terms of the best equipment (SSD drives and graphics card) and the best way to set up AfterEffects/Photoshop projects using these SSDs.
For example:
1. Should I be purchasing 1 or 2 SSDs, and how should I be using these drives to optimize my system for AfterEffects and Photoshop?
2. Should I install my operating system (I'm on OS 10.8.5 but plan to upgrade to Mavericks when I upgrade to CC) on one separate SSD, and then install my Adobe applications on a 2nd SSD, or can I put both the operating system and applications on a single SSD? And should I be saving my projects on a SSD (if so, which one, if I'm supposed to purchase 2?
3. Should I assign a 2nd SSD as a scratch disk for AfterEffects or Photoshop?
4. I plan on using my current external hard drives (a 12 TB RAID array connected via eSATA) to store the footage and Photoshop elements being used in my AE projects (these files will be multiple GBs, and I can't afford to purchase SSD drives to hold these elements on) and also to store the renders from AfterEffects (which will also be very large files). Is this OK, or will this slow me down and negate whatever speed I've gained from moving to SSDs?
5. In researching how to switch over to SSD, I've considered purchasing 1 or 2 SSD drives. The one I'm currently looking at is called the Murcury Accelsior_E2, a PCI Express SSD sold via OWC. It comes in a few different sizes (120 GBs, 240 GBs, 480 GBs, 960 GBs). Just wondering if this is a good purchase -- the reviews seem to be very positive:
http://eshop.macsales.com/item/OWC/SSDPHWE2R960/
6. I'm also considering upgrading my current graphics card (ATI Radeon HD 5870) to the NVIDIA Quatro 4000 or NVIDIA Quatro 5000, but I'm wondering how much of a speed boost this would give me.
Here's an overview of my current system:
Computer: 2010 Mac Pro with 2x 2.66 GHz 6-Core Intel Xeon
Memory: 64 GB DDR3 ECC
Graphics Card: ATI Radeon HD 5870
Hard Drives (Internal): 2x 2TB Hitachi HD
Hard Drives (External): 12TB OWC Mercury Elite Pro RAID drive array (connected via eSATA)
Apologies in advance for the long message, but I've always recieved great advice from these message boards and I'd appreciate any help!
Thanks,
Dan

Thanks so much for jumping back into the discussion, The hatter! I had some earlier questions from before that I was hoping you could answer:
Currently I own a 12 TB OWC Mercury Elite Pro RAID drive array (connected via eSATA) which I use to save projects, project files, and renders. So (unless I am mistaken) you're recommending that I continue to use this RAID array to save projects, project files, and renders.
(I was looking into purchasing a Mercury Accelsior_E2 for my SSD via PCI -- it has eSATA, so I can continue to connect my RAID array)
Then I would use my new SSD via SATA II for my system, apps, and OS (minus home folder media files, data, documents) and my SSD via PCI for scratch disks for Photoshop/AfterEffects.
Currently I have 2 x 2 TB internal hard drives, which have all my OS + home folder media files.
Can I get more details in terms of the step-by-step instructions when it's time to install/clone? Here's how it looks to me (apologies if I have this out-of-order, and feel free to correct me if I've missed a step or have it wrong -- thank you in advance!):
1. Purchase SSDs (via PCI and internal SATA II) and install them inside my Mac Pro.
(Is there any formatting I need to do at this point to the SSDs once they are all plugged in...?)
2. Install TRIM Enabler
(Once it's installed, what do I do with TRIM Enabler? Is it an app that runs 24/7 in the background, or is it an app that I need to launch on a regular basis and perform commands on the SSDs...? Very confused on what TRIM Enabler does.)
3. Use CCC to clone system from old internal hard drive to new internal SSD drive. When using CCC, deselect media folders in home account before cloning (so I am NOT cloning media folders from old hard drive to new SSD drive).
(What specific media folders should I be deselecting? I'd like to keep my music, movies, iPhoto/Lightroom files, and email archive where they are now -- on the 2 x 2TB internal drives that shipped with my Mac Pro. Is there a link that provides more info on this process? Never used CCC before but I assume it's not too hard to use...?)
4. CCC clones system gets 'cloned' (minus the media folders) to the SSD that is installed via SATA II in empty internal drive bay inside Mac Pro.
5. Repair the SSD with DU after cloning and before using and booting from SSD.
(What is DU? How does it work? Not familiar with DU...?)
6. Reboot computer from system running on SSD.
7. Open Photoshop/AfterEffects (now running from SSD) and assign new scratch disk (the SSDs on PCIe SSD controller).
8. After 100% sure that system + apps that have been cloned is working via SSD, delete ONLY system and apps from old hard drive (but do not delete media files).
(Now that my system is on a separate SSD drive, when I do things like purchase new music from iTunes, will it get downloaded to the old location (my old hard drive with all my media)? In other words, are there steps I have to perform in order to relink my media folders now that they're on a separate drive?
Thanks,
Dan

Hi friends i have mac pro . every day start up probelm

hi friends i have mac pro . every day start up probelm how can i solved pls tell me
<Email Edited By Host>

Hello, which exact Mac & OS version is it?
If not 10.7/Lion try this...
Could be many things, we should start with this...
"Try Disk Utility
1. Insert the Mac OS X Install disc, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu at top of the screen. (In Mac OS X 10.4 or later, you must select your language first.)
*Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
3. Click the First Aid tab.
4. Select your Mac OS X volume.
5. Click Repair Disk, (not Repair Permissions). Disk Utility checks and repairs the disk."
http://docs.info.apple.com/article.html?artnum=106214
Then try a Safe Boot, (holding Shift key down at bootup), run Disk Utility in Applications>Utilities, then highlight your drive, click on Repair Permissions, reboot when it completes.
(Safe boot may stay on the gray radian for a long time, let it go, it's trying to repair the Hard Drive.)
If perchance you can't find your install Disc, at least try it from the Safe Boot part onward.

Upgrading my FCP X Mac Pro

Upgrading my FCP X Mac Pro
by Michael Holmes on Jul 24, 2012 at 11:18:08 pm
I shoot videos of local bands as a hobby. I have been mixing/mastering songs for these bands for 15 years, so this is a natural extension.
I would like to upgrade my 2010 Mac Pro 2x2.4 Quad Core. This computer is only for (1) FCP X and (2) Pro Tools HD Native. Currently my system works well on single cam editing as long as I don’t use a 3rd party plug-in…………then it drops frames big time. I am about to start using two FS100 camcorders, and I am worried that the Mac Pro won’t handle dual cam editing very well. I edit 100% in ProRes.
Are the following decisions good ones?
(1)     A Crucial M4 256 SSD for OS/Apps. I plan to buy, this seems like an obvious upgrade. I only have 75GB on the OS/Apps HD, so 256 should be sufficient.
(2)     A RAID card. I don’t plan to buy this. I am not even using software RAID. Only one of the other three 2TB Hitachi 7200RPM SATA II drives is dedicated to video files; the other two handle Pro Tools files, and backup duties. I don’t currently have room for a RAID card, since the four PCIe slots are/will be used:
(a)     ATI Radeon 5770
(b)     Pro Tools HD Native
(c)     Card for external monitor (maybe)
(d)     Card for LTO 6 tape storage (planned, as soon as LTO 6 is available).
(3)     An upgrade of the ATI Radeon 5770 graphics card. I don’t plan to buy this. I haven’t seen anybody saying this will give me substantial FCP X performance improvement.
(4) Increase memory. I will do this if it will help. I have 16GB, and I can go up to 32GB.
(5)     An Eizo ColorEdge CG275W LCD Monitor. I don’t know what to do on this. I am currently using an HP 2711x monitor that I calibrate with a Spyder4PRO. I deliver H.264 QuickTime movies that are viewed on computer monitors. Probably 30% are uploaded to the Internet. Often the QT movies are given to club owners when bands try to get bookings.
However, I will probably start to deliver HD video DVD’s soon, especially for the club owners. These will be better quality and increase the odds that the club owners will actually view them. So, right now the product is viewed 100% on computer monitors, but later this year it will start to be viewed on televisions.
BTW, I have no idea what card to buy for this monitor, if I get it.
Are these the right decisions?
Note that I am doing very little to address the “dropping frames” issue, which is the biggie. Am I overlooking something obvious?
Thanks!

What about just getting two SSD's for the drive bays:
(1) One 256GB SSD for OS/Apps
(2) One 512GB SSD for Event/Project folders.
512GB would be tight on some shoots, but I could even go to a Mercury Electra 960GB SSD.
Yes, very pricey storage, but if this would solve data transfer problems, it would be worth it.
If I only need one video card, I can use a PCIe slot for an external SATA drive unit (4 bays) I already have to handle all backup storage. So, the loss of the two HD bays to SSD would not be a big issue. HD bays are less dear than PCIe slots.

i have mac pro i7 , 8GB RAM , 750 HDD , can i install windows 7 ultimate 64 as a parrallals desktop?

Hello and welcome to Apple Support Communities!
Yes, you can install Windows 7 Ultimate 64-bit in your Mac using Parallels for Mac. Just follow the instructions of the virtualization programs during the install. Should you need any assistance with the installation process, I strongly recommend contacting Parallels Tech Support (you must register with Parallels in order to have tech support).
Alternatively, you can always use Apple's BootCamp if you want to run Windows natively in your Mac. Check their support page, Apple has a lot of good links explaining this solution.
Hope this helps!

Is it worth the upgrade to a new Mac Pro?

I have a question about the new Mac Pro. I have a 1st Generation Mac Pro (the one released in 2006). I primarily use it to do a lot of motion graphics and video editing/effects. I use Final Cut Pro, Motion (I have FCS 2), After Effects, Cinema 4D, etc. Would it be worth upgrading to the newer Mac Pro? Would I notice much difference in rendering speeds, working with 3D, etc?
My current Mac Pro has 5 GB of Ram, and the NVidia GeForce 8800 GT graphics card; 2 x 2.66 GHz Dual-Core Processors
I'm really debating on selling my Mac Pro and purchase one of the 2009 Mac Pros but only if I would really notice much of an overall difference.
Thanks in advance for any answers and input!

Hi, it really depends on what you plan to do with the computer. If running windows in 64 bit mode is a worry for you, then I would trade your 2006 for at least a 2008 mac pro. The Harpertown mac pros are still considered by many just as fast as the 2009, if not faster in some things. Remember, it is hyper threading that gives the 2009 their power and the speed of 1066mhz DDR3 memory.
If you plan on just using the mac pro for light video editing and encoding and using pro apps, the 2008 mac pro will be more than enough. I had a 2006 mac pro going from a G5 Quad. Once I found out that I really enjoy running windows on it and the thought of a new cinema display, I decided to trade my 2006 for the 2008. Sometime in the next few years, I will then trade up my harpertown for the Nehalem mac pro and so forth.
You are right! very few people these days have 2000+ dollars to spend outright on a computer, but I got a great deal on my 2006 trade which was 1850 - the 2008 3.0 harpertown for 2300.00

Upgrade to Lion on Macbook Pro

I purchased my Macbook Pro in April, 2007. Still runs very well. I have OS X 10.6.8. Want to upgrade to Lion. My processor is 2.16 Ghz. Memory 1 GB. Need 2 GB at least for Lion, so need to purchase more memory. On Apple web site they sell 2 GB and 4 GB memory, but for 2.2 Ghz and up. They do not note 2.16. Does this matter or do I need to also update my Intel Core Duo to 2.2 or higher? Or can I purchase 2GB or 4GB memory and install and things will be fine? Thanks. Mark.

You ought to purchase your RAM at OWC or DMEM where you will find it's much less expensive than what Apple charges. You can purchase any RAM just so long as it meets the specifications for your model.
I also suggest you get more than 2 GBs if you plan to upgrade to Lion. At least 4 GBs would be my suggestion.

Should I upgrade to Lion? Have Mac Pro, 2.66Ghz, Core i7, 4GB memory, S-Leopard, purchased 11-2010.
