Potential Switch to Mac Pro

I may be switching to a Mac Pro from a PC and had a few questions. I have worked a lot with *Nix so I like the idea of switching due to OS X being based on that.
Here are my questions:
1.I am seeing a lot of problems with Leopard on these boards. I have noticed though that a lot of them seem to be from people upgrading and not many from brand new computers. Am I correct in that assumption?
2.I have a Buffalo WHR-HP-G54 running DD-WRT, should that work with a Mac Pro?
3.I have a bunch of fonts on my XP Pro system since I do a lot of creative work (photo,web,video,etc) can they be put on the Mac Pro without issue?
4.I have seen a few problems with people saying the usb hub in their cinema display causes problems, is it just the cinema displays or any monitor?
5. Are Mac Pros prone to overheating? If so is there something I can do to avoid that? I live in Reno,NV and it can get hot during summer so that is a worry for me.
Sorry for all the questions but I just want to make sure I cover all my bases before making a huge switch. To be honest I used to be a die-hard PC fan and didn't like Macs except for the OS and now that it looks like Vista may be the new ME and I want something different I figure it may be a good time to eat some crow and switch
TIA!!

I can only comment on a few of the items.
1. I haven't had any 'real' problems with any of my upgrades to Leopard on my various machines. Leopard has been very stable for me.
3. GFTrout is right on the fonts, but there are solutions for PostScript fonts. Here is [one|http://guides.macrumors.com/UsingWindows_and_X11_PostScript_Fonts_in_Mac_OSX].
5. None of my Mac Pros are prone to overheating. It can get pretty hot here in OKC too. I wouldn't think you would have problems unless the room it was in wasn't air-conditioned. My office at home in the summer (with AC on) usually ends up being in the upper 70's to lower 80's during the day (west-facing with windows.) As for avoiding overheating, it is wise to keep the MP off of the floor, plenty of air circulating at the front of the MP and a decent amount of space behind the MP for exhaust. The exhaust can get pretty hot so you want air to be able to get behind the MP to dissipate that heat.
Hope this helps...

  • PC user switching to Mac Pro - Internet connection/Mail questions

    Hello:
    I am a long time PC user that is going to switch to the Mac Pro. I have two questions relating to the Internet/Mail.
    (1) On my PC, I have an ADSL modem to connect to the internet. Can I plug that directly into my Mac Pro's Gigabit Ethernet port, or do I need other Apple Hardware? I have no interest in going wireless.
    (2) If/When Parallels is working for the Mac Pro, can I use Apple Mail, then attach files from Windows Office products (Word, Excel, Visio, etc) via Parallels. I want to migrate to Apple products, but at this time, I still need my Office products.
    thanks in advance for helping this Mac newbie.

    Welcom to the Apple Forums!
    If your modem has a ethernet connection, then you can
    connect it with a cable to the Gigabit networkport on
    your Mac. Just like the same as Windows.
    Whit parallels workstation is it possible to acces
    the Mac disk. So, you can save from windows on your
    macdisk. And then, you can acces it with mail.
    You said: _from Windows Office products (Word,
    Excel, Visio, etc) via __
    Remember, there are also office products for the Mac.
    When you are using Parallels to run Windows, it is
    not possible to acces de Windows HD from Apple. So if
    you want to share files betwee Windows and Mac, you
    have to do ut from windows. Windows can read/write
    the Mac disk.
    You can set up a share folder with Parallels between Mac and the PC side which is what i do. Maybe work on something on XP than put back in the share folder than see it on the other side . But seeing externals and such from the PC side i can't seee them but the share folder does work. I switch my office to the mac side and it works fine and use Entourage as my mail client, looks and smells like outlook

  • Is it ok to switch my mac pro boot drive to port 4?

    hi, my brand new mac pro hard drive is kind of loud. is it ok to switch my main drive to port 4 farther back in the computer?
    will it be slower?
    thanks so much!

    There will likley be no discernable difference.
    If you do not have a drive in the first bay, it may change the airflow slightly, as it will no longer act as a dam to improve the airflow of the intake fan.

  • FCP 5 unbelievably slow to compress video on Mac Pro hardware.

    Hi -
    I am compressing some HD video to H.264 format on a Mac Pro...
    The version # is 5.04 - Not the Universal version which I just discovered needs to be crossgraded to. But that is a different topic.
    I have about 22 minutes of video which seems to take anywhere from 2 to 5 hours to compress to the MP4 format. The machine claims that 2.6 out of 4 processors worth of processing is going on... Perhaps this is just an artifact of the emulation of the PPC hardware/software... But - yuck.
    I opened the process window for the Final Cut Pro Process and it showed a zillion faults.... And then I sampled the process and ended up with a thread listing as such...

    What Brian said. FCP will not run well, if at all, under Rosetta. It certainly won't give you any where NEAR the potential of your Mac Pro. I have friends with your system setup and they can't believe how fast it is...

  • Does running Mac Pro for many hours hurt it?

    Hello,
    I'm planning to run my MacPro for 8-10 hours a day and I was wondering does running the computer for many hours during the day is potentially dangerous for Mac Pro?

    No problem at all. However, under heavy usage you will find that it better to have enterprise class drives and a professional class UPS. The Mac Pro will actually have no problem with running 24/7/365.

  • Question about parts compatibility G5-Mac Pro

    Hello! Thanks to anyone that has some insight for my question
    I have a loaded G5 powermac and am wanting to make the switch to Mac Pro for some time now. I have 4gigs of RAM and 2 400gb HDD's in my G5. Would I be able to use any of that in the Powermac? Or is it all incompatible now?
    Thanks for any responses...

    So the RAM will work as well? The drives are SATA.
    Well a few reasons for upgrading are that my apple care will soon expire, about 6 months left and I cant renew it ( I wish I could). So if something does finally break down on me, I would be throwing money at it to fix. Plus I would love to run Parallels and BootCamp and just get into the next generation of mac computing. With leopard coming out and all things advancing...i already feel left behind! haha...the marketing demons have me.
    This powermac is by no means obsolete and more than fulfills my needs. Settling for a macbook pro would be awesome...but looking at some of the refurb mac pro's I was thinking I could super fuel it with my current G5 parts.
    Thanks for your replies, gurus!

  • Best Mac Pro Configuration for LR?

    For various reasons I'm planning on migrating from my home desktop pc ( 4 year old core2 2.4 ghz xp pro sp 3 32bit accessing 2.93 out of 4 gb ram) to a new or (lightly used recent) Mac Pro desktop.  The Mac Pro is available in a lot of different configurations and I would appreciate advice on how many cores and how much ram I actually need to comfortably run LR3x and its eventual upgrades (within reason) and PS3 for now and later probably whatever is current.  I'm a reasonably advanced amateur photographer; I shoot what interests me and now use LR for 90-95% of my post processing of my raw Leica and Canon image files. I do use some add-ons (SilverEfex Pro2 and such).
    I understand from reading some articles that too much muscle in the Mac Pro can actually slow down LR, so if this is true I'd like to stay svelte; also economic issues are somewhat a concern.
    I have already considered a laptop or an iMac and decided the Mac Pro is what I want.  The question is just 'what will work best for me'?
    Thanks in advance, and if you need more information just let me know.

    @ Bob: I think you may be have acquired some misinformation somewhere. There is no such thing as "too much muscle" in a Mac Pro in relationship to Lightroom - or any other program. OS X allocates resources to applications as they need them. Unused resources remain idle or are utilized by other applications.
    Adobe posts the minimum system requirements for their applications, but these should just be taken as a starting point. In my opinion you should buy the best Mac Pro your budget can handle - and maybe a little bit more. The computer is an investment, after all, not a luxury. That said, what you need to run Lightroom efficiently and what Jay needs to do video editing are not necessarily the same. For video rendering more cores are better. For Lightroom the question of the number of CPU cores is less critical. Whereas, CPU speed is more relevant. For both, the amount of RAM can make a big difference.
    I recommend as a starting point, at least a quad-core Mac Pro with 4GB of RAM. That would do if you were looking at an iMac as well.
    I can understand, though, how looking at the current line-up of Mac Pros can be confusing. The older Nehalem powered Mac Pros look faster for less money, but this is now old technology. The new Intel Westmere CPUs offer significant improvements in performance. Unfortunately, they are also much more expensive than any previous Mac CPU upgrade. But if you want to "future proof" your new Mac, one with a Westmere CPU is the better way to go. The 8 core model Jay went with seems to be the best value, with two quad-core 2.4GHz Westmere CPUs. However, for just $200 more you can get the 6 core 3.33GHz Westmere CPU. For the purposes of Lightroom, the faster CPUs in the 6 core model will make more of a difference than the two extra cores in the 8 core version. And the 6 core version will handle just about any multi-tasking job you throw at it; that it, using Lightroom in conjunction with Adobe Photoshop, for example.
    To confuse the issue a bit more, however, if using Lightroom is your primary concern, a Mac Pro may be overkill. The new iMacs, which came out since you started this thread, are excellent machines. You could get a lot more for your money with a 27" iMac, BTO with a quad-core 3.3GHz Intel Sandy Bridge CPU, 8GB of RAM and a 2TB hard drive for roughly $1,000 less than the Mac Pros you're looking at. Along with a capable computer you get a beautiful 27" screen on the iMac. I'm not sure why you think you need the Mac Pro. The iMac can now take up to 16GB of RAM. If you were to get one with 8GB factory installed by Apple - as a BTO option - there would still be two empty RAM slots available for a future upgrade. You could add an SSD to the iMac and still pay less than you would for the Mac Pro.
    And the new iMacs have a Thunderbolt port; in fact, the 27" models have two Thunderbolt ports. These offer much better throughput and greater flexibility than any previous I/O connection. With an appropriate adaptor you can use almost any external device, including eSATA, FireWire 400 and 800, USB 1, 2 and 3 and even Ethernet and an external monitor. Of course the iMac still has a Firewire 800 port and four USB 2 ports, and an SDXC memory card slot. For what it may be worth, I suggest you give the iMac another look. Your budget will thank you.
    TheWhiteDog,
    Kinda, Sorta, Maybe...  :-)  The cost differential between the 8 and 6 cores is $200 when comparing new to new.  I picked up the 8 Core Westmere 2.4 for under $3000 because it comes up on the Refurbished side... So now we're talking $700 difference.  the difference in price can be used for memory (I got 4GB for $50 at OtherWorldCmputing's "Garage Sale), a drive.. any number of things.  Since Apple treat refurbs as new for warranty purposes (including AppleCare), I didn't see any reason not to go with the refurbished model..
    I agree a higher clock speed is better, but as you said, I also do video so more cores helps (amazingly helps)..  Yes, for LR 6 3.33 cores may outperform  8 2.4s, but the 8 core machine flies with LR.
    As for iMacs vs. Mac Pro..  the biggest difference is that you find with any desk top vs. a "fixed" machine like the iMac.  The upgrade as far a internal (and external) drives on a Mac Pro is so much better as well as to upgrade video if I want to in the future as well.  As for Thunderbolt, clearly a lot of potential, but it is a daisy chain design and the slowest device in the chain can slow down everything if not done right.  There's also not a lot out there for Thunderbolt yet.. and I'm not 100% sure that there won't be an PCI card for Mac Pros for Thunderbolt (although it could be a system board feature only).
    At under $3000 with 6GB of memory and a 1TB 7200 drive, combined with growrh potential and the Mac Pro I think has a longer shelf life vs. the iMac.  Without those Thunderbolt adapters in the market place, you're stuck with FW800, which is a lot slower than even eSATA for external drives.  Since most all the LR recommendations are to split the catalog away from the cache and away from the images themselves, it's a trickier and more costly venture on the iMac..  The 27" screen in nice, but I'm not a big fan of glossy screens.  I don't think any of those allow you a matte finish option like on the Macbook Pro.
    Bottom line Bob is there are different choices for different budgets... Heck I went with a 17" Macbook Pro for a long time, using an inexpensive Expresscard 34 to hook up external eSATA drives and a second 24" Dell monitor..  Great combo and I always had the portability aspect of the 17" for client work, being tethered, etc..

  • How do I get my Mac Pro to see the second monitor through a video splitter and/or switcher?

    In a recording studio we have a Mac Pro with two video display monitors in the control room and we want to be able to show the content of the second monitor to the person in the recording room on a big display monitor there. However, when we interpose a switcher or splitter between the computer and the second monitor so that we can (with a switcher) switch the second monitor signal from the control room monitor to the record room monitor or (with a splitter) split the signal to go to both monitors, we have no luck. On startup the computer does not see the monitor through the switcher, so it doesn't recognize its existence. If we start the computer up without the switcher in the signal chain, it sees the second monitor just fine, and (weirdly enough) we can then change the cabling to interpose the switch, which then works to switch back and forth between second monitors (control room and record room), but that cable swapping's a royal PITA. We want a simple solution that will allow us to start up the computer, see the second monitor in the control room, then choose to show it to the person in the record room with a simple flip of the switch (or even better, split the signal so it's available both places). The splitter we've tried most recently is this one: http://tinyurl.com/curen39 I'd appreciate any advice from people who have tried this configuration or something similar with success. We have a full ProTools HD Accel 3 system installed, so there's no room to install a second video card. Thanks.

    Thanks for the response! Yes, it's a 5x70 video card, a 5770 I believe. In any case, it does have the three ports, but (a not-well documented fact) that doesn't mean one can really get three full-resolution signals out of it at one time, as you alluded to in your message. So, yes, we did try hooking all three up directly to the computer, but the computer would only recognize two of those monitors, and the only way to get it to "de-recognize" the second monitor and recognize the third monitor was to physically disconnect the second monitor.
    I did say when you want to connect three monitors to 5x70's there are some rules to adhere to.  These are covered in the first two apple docs mentioned above, or by title:
    Mac Pro (Mid 2010), Mac Pro (Early 2009): Issues with three displays and multiple DVI, HDMI connections
    Mac Pro (Early 2009), Mac Pro (Mid 2010): Supported display configurations
    The general gist of these rules is that to drive three monitor son a 5x70 you need two active adapters.  That is why one of your monitors was disabled when you tried to add a third. 
    Here's a good explanation of what's going in here and why you need two active adapters on these cards:
    Active vs. Passive Displayport adapters *the truth*
    If you use DVI monitors and any of them have resolutions less than 1920 x 1200 then you can use single link active adapters. The "AMD Eyefinity Validated Dongles" chart shows some active (and passive) adapters that are acceptable.  For example of a single link DVI active adapter is the Accell B087B-006B.  An example of a dual link DVI active adapter would be the one from monoprice.com if you need to connect monitors with a resolution greater than 1920 x 1200.
    I'm doubtful that SwitchResX would be able to convince the computer that there were only two monitors connected and direct the second monitor signal to the correct place, but it certainly seems worth a try, so thanks for the idea! Any other ideas are still welcome in the meantime.
    I'm not doubtful.  It is a very powerful utility for dealing with all aspects of multiple monitor configurations (they call them "Display Sets") complete with forcing EDID information if necessary.  The different configurations can be controlled with a (contextual) menu and/or hot key.
    SwitchResX is academic at this point if you want to have all three monitors connected.  You would need to get that working first.  Then use SwitchResX to vary the configuration combinations.  So if you go this route the "name of the game" is figure out the active adapters you need.
    I only described in general terms above about the adapters since you never said exactly what kind of connections these monitors require (single link DVI, dual link DVI, hdmi, mini-displayport, vga). 

  • My mac pro takes long to switch on

    Recently I moved from one country which uses 240V to a country that uses 110V
    I noticed that I need to push the power button a couple of times to turn it on. Once it's on it works perfectly.
    Can someone guide me if there is a problem or not and what I can do to switch it on with just one push?
    Many thanks

    Hi Jgalear4m,
    If you are having unusual behavior from the power button on your Mac Pro, you may want to try resetting the System Management Controller (SMC). You may find the following article helpful:

  • Switching From PC to Mac Pro

    OK, I made the leap and ordered my new Mac Pro. Seems like the time is right to join the Apple bandwagon.
    I would like to hear from other people who have made the switch on how their experience with Apple is? After reading the Discussion area here, I am beginning to wonder if I did the right thing.
    Come on folks. Make me feel good

    I am such a Mac fan now it is downright scary. I was never a Windows user and was IBM's official "OS/2 Guy" for many years. Apple moved to Intel just after IBM announced the end of support and sales of OS/2 and that was enough for me.
    The transition was pretty seamless. Both OSes are object oriented unlike Microsoft's OS. Installing a printer under OS/2 was a hit and miss kind of thing due to driver age. When I plugged in an HP ColorLaserJet I had no idea if it worked or not. There was no announcement or sound. So I sent something to be printed and it rolled out like a champ.
    My biggest frustration was with the Superdrive. I put a DVD in, watched and loved the way Mac handled it but for the life of me couldn't figure out how to get the disk out of the drive. There is no drive button. Now I know why. None is needed. There are all kinds of ways to get the Superdrive to eject a DVD and so simple I felt incredibly stupid when they were revealed to me. "You're kidding! Oh my GAWD, how simple is that?"
    Or to install or delete a program. This will rock your socks. You just drag a program icon to your applications folder and if you don't want it anymore, just delete it. Presto! Gone. To upgrade an installed program just drag the upgrade to the applications folder and OSX asks if you want to update the current program. You say yes and there is no big hoopla or twenty minute wait while the system goes through hoops. Open the program and it is updated!
    I bought my Mac Pro within the first 17 minutes of online availability. Same with my BlackBook except I kept speed dialing because they weren't quite ready to accept my order. Now?? Now??? Can I order now?? I bought two Intel iMacs for the office - 20" and 24" and love love love 'em.

    Assuming you are disconnecting from line power, when you say switched on, do you mean it was shutdown or in sleep mode?  If sleep mode the battery will still drain because sleep still keeps some things active and the battery does drain a little.  However, to go from 100% to 79% charge overnight is a bit excessive in sleep mode.  Unless you have some processes set to activate over night by the cron file and do things like backup the system.

  • Switch On Time Mac Pro 5.1

    Hello,
    i have a Mac Pro 5.1 Mid 2010, 2 x 2,93 Ghz.
    When i switch on my Mac Pro with a RAM-Configuration of 4GB, it takes about 4 secounds to see the grey screen with the Apple-Logo.
    A RAM-Configuration of 24GB uses about 24 secounds to see the grey screen.
    Is that normal that a Mac Pro with more RAM uses more time to come up?
    I´m not talking about booting from disk, only the time after switch on to the grey screen.
    Thanks to all

    Use whichever you like, but they will not mix-and-match.
    Early on, larger sizes were only available as RDIMMs, which would not play nice with others. This was a requirement because those early DIMMs required multiple chips, so you needed the Register to provide one apparent Bus load.
    Today, only the 16GB modules are RDIMMs.
    So if you are not headed for 64GB, use unregistered.
    In the US, I recommend this low-cost high-service Vendor:

    Their line-items clearly call out which are Registered.

  • Mechanical or digital source switch for 2 Mac Pros on one 30" display?

    I have a 30" display, and use it at the maximum resolution of 2560 x 1600 on my Mac Pro with the NVidia 8800GT card. I have a second Mac Pro with a similar configuration.
    I would like to find a switch to send the video to either of these machines.
    The DVI switches I have found do not support the higher resolution of the 30" display.
    Does anyone know of a device that would allow me to switch the source for the 30" display between two machines?
    Thanks....

    You need a dual-link DVI switch, such as
