Mac Pro 2007 with Nvidia 8800GT screen redraw problems on Mac OS 10.5.2

I seem to be having a slight screen redraw problem. Such as when grabbing the browser window and moving up and down it seems the redraw can't keep up,also seems problematic when watching flash or other video online. It does it in the finder too for windows listings or in icon view there is a fluttering or flashing back and forth, kind of like a white super split second flash when dragging the window box smaller or larger not as bad as when making smaller. Hard to describe but my original Ge-force that I pulled was not having these characteristics. I figure that the drivers need tweaking. In windows I am not getting these results. I have newer boot camp installed as well as the leopard graphics update done so I am trying to see if others are having a slight problem or maybe it is me.
Also I make certain it is not heat related as I monitor that and it does not matter at what temp it is.

Here's another similar experience -- and my solution.
I bought a Quad-core 2.8GHz (8GB RAM) Mac Pro in May and got the "better" Nvidia 8800GT. I thought I was happy, but there were redraw issues after sleeping and a display "roughness" I found annoying. Upgrading to OSX 10.5.4 didn't help.
I found it to be mostly absent on startup, but sleeping the Mac would bring it on. I.e., after sleep, the relatiionship between the 8800GT would be different than before. when I logged out and in again, the problem woud vanish. No what I expect from a "superior" graphics card. I ascribed it to funky drivers from Apple.
The store I bought the Mac from offered to swap for my suggestion of an ATI HD 3870, so I went for it about a week ago.
This card is far smoother than the 8800GT and just as fast in rendering benchmerks for graphics. (I'm not a gamer.) I am a happy camper! There is no stuttering, oddball redraw, or jerkiness as there had been with the 8800. It's perfect! Never mind that it may be 5% slower for gamers, it feels faster for my use.
BUT NOTE: As I now see from reading several forums, I wasn't alone is getting a screaming-Mimi at first! The first 3870 ran at nearly full fan speed at power-up. The speed changed a little with resolution changes on my big Mitsubishi CRT monitor, and actually stopped when I switched to 1080x1920 @ 72Hz! Then the fan would start and quit, start and quit randomly -- convincing me it was defective.
I returned this RED-shrouded unit and the store replaced it, this time with (randomly) a BLUE-shrouded unit. (Slightly lower serial.)
Bottom Line: This replacement 3870 is quiet as a mouse! Fan runs near-silently at startup and after hours of regular use in a 75ºF room. I get the distinct feeling that a bunch of cards with wonky fan controllers were built, and some of us got 'em.
Bad News: The ATI HD 3870 does NOT support multiple refresh rates under Windows XP-SP2 booting the Mac Pro, with or without Boot Camp drivers installed. No version of the ATI drivers fixes this, and ATI does not officially support Boot Camp yet. You can choose a resolution okay, but you're stuck at 60Hz refresh -- a pain for those of us who hate 60Hz flicker. (I like 100Hz refresh.)

Mac Pro (2008) with Nvidia 8800GT - Adding a second (ATI 5870) possible?

Hello there,
I have a 3,1 mac Pro with the bto Nvidia 8800 GT in it, but buying the Apple/ATI 5770/5870 as 'upgrade' is somewhat expensive (where do these prices come from??), I was wondering whether I could 'just' buy a normal 5870 (for less than the half of the apple one) and add it to the system to be used under Windows only (and hook it up with a second cable to my monitor) - so I keep the 8800 for EFI boot/mac os x, but would use the 5870 under windows.
Now what I was wondering is, do they fit in the 2008 mac pro case? And do I need any particular power cable for the extra card?!
Cheers and Thanks,

Mac Pro 3.1 Nvidia 8800GT problem

Here I am again guys
and after about 3,5 months from 8800GT failure and rebaking it succesfully, the card is dead again, so I baked it once more.
I am on OSX Yosemite 10.10.2 now with my Mac Pro 3.1. I don't use photoshop or any 3d game.Beyond safari, firefox, mail, youtube, itunes and some other common apps, I use Wmware for win7 and xp compatibility and there I have installed Autocad 12 but I don't use it for 3d design. I do some movie format conversions with Handbreak (6-10mins job) every now and then. Recently, last 15days, I started to use Garageband and a little imovie 2-3 hours a day both of them. I understand that, this is not heavy duty jobs for the graphic card!!!
What's surprising me is that MacPro works without the card installed!!! via Teamviewer.
I have made a few secs mov conversion to mp4 format with Handbreak and also played a few secs movie with quicktime, I am afraid to use the mac for a long while because I don't know it's capabilities in this situation and I don't want to have a severe damage.
I've always noticed that Handbreak was taking all the cpu juice when doing convertions although I thought that the GPU does the major job for that. But then, when the GPU gets working? Only when sending picture to displays? I don't think so...
So question 1 is: when the graphics card get's into play....and get stressed by my Mac?
and question 2: I am planning to buy a low budget nvidia card for pc -non EFI so no Boot screen- and install it as a main card.
I am thinking to replace my 8800GT with this Asus gt740
http://www.asus.com/Graphics_Cards/GT7402GD3/overview/
or
http://www.amazon.co.uk/gp/product/B...A3P5ROKL5A1OLE
Then install again the rebaked 8800GT and leave it unconnected to screen. I will connect it to a screen only when I 'll need the boot screen, or update OS. Will this combination make the 8800GT to stress and overheat as before?
question 3: I use the term overheat just because the card fails, I don't know a way to measure the card's temperature and I pretty much like to, just to see what's happenning to card under any jobs..

After checking connections, I would try a NVRAM reset:
http://support.apple.com/kb/HT1379
If it still doesn't show, I'd pull it and connect it to a different machine.
If it does't show there, I'd call it dead.
Oh, and as for the jumper, I wouldn't change it without changing the second drive as well.

Mac Pro 2007 with 3 displays?

I have a Mac Pro 2,1 (late 2007).
I'm running 2 displays via my Nvidia quadro fx 4500 video card. These are standard DELL 22" monitors (DELL 2208WFP)
I'd like to run QT videos (via my music software DAW) to a Toshiba 42" LCD screen. It has old VGA input (along with S-Video and RCA).
I'm currently using a FW Canopus box to do this (via S-Video), but it's no longer behaving well with my softwarre MOTU Digital Performer 8) and OS (10.6.8).
Is there any way I can run this 3rd diplay (Toshiba) without having to install a 2nd video card? (i.e. will a DVI 'splitter' do this?).
Thanks!

Matrox makes a "Triple Head2Go" device that will split computer video over multiple screens.

Or, if you want a real HDTV signal, look for a card from BlackMagic or AJA.

My Mac Pro (2006) with NVidia GeForce 8800 GT is not detecting a second display. What can I do?

My Mac Pro w/ NVIDIA GeForce 8800 GT does not detect a second display from the System Preferences / Displays. Even though I select the "Detect Displays" button, nothing happens. I also have Bootcamp and Windows 7 in a partition on my drive. When I operate with Windows 7, there is no problem detecting both of my displays. However, when I operate with Windows 7, there is no sound signal sent from my sound card. When I switch back to the OS X then I get a sound feed from the sound card, but then it will not detect more than one monitor. I'm ready to pull out my hair. Anyone have suggestions?

Mac Pro (early 2008) NVidia 8800GT display problems (blue/green lines)

I see others have touched on this topic a bit but not quite the same as my problem
Every 2 - 3 days, I have to reboot my Mac Pro because my display starts showing the dreaded blue green outlines and lines..
I've called Apple (of course they are not going to admit that others have this problem) and they told me to reset the PRAM, which I did to no avail of course.
I've had this card for 3 weeks, and they are telling me that I need to bring my mac pro to the apple store. Yeah right, like I can afford to bring my computer in a for a few days, when that is what I use for work everyday (computer programmer).
When I asked them to replace the card, they told me I have to bring it in, then I told them they can just send me a refund and keep this crap. Which the support rep said, I can't authorize that. Hah.. Apple is really digging on my last nerves these days.
I did not have this problem with the stock ATI.
Any suggestions would be appreciated.. I've run hardware tests off the Apple DVD and using techtool pro, nothing fails.
I've heard reports that this card is a major dog (slow) in leopard, that the ATI actually out-performs it, anyone else here anything like this?

What monitor are you using it with? If it's a 30" Cinema, this problem has been around for a couple of years without any resolution - there's a long thread about it in the Displays forum.

Mac Pro- 2 monitor Time Machine screen redraw issue

Late 2013 Mac Pro
OSX V. 10.10.3 (which includes the supplemental install that came a week later)
30 Inch Cinema HD Display
23 Inch Cinema HD Display
When I enter Time Machine I see the attached image on my 30 inch display (my primary display). the 23 Inch does NOT go black- it just displays whatever was showing prior to entering TM. The black box appears to be the 23 Inch Display's "cover" that has been slid over onto the 30 inch display. Time Machine DOES back up regularly according to the TM pull down. You can see the cancel button obscured by the black box.

Open the Mission Control pane in System Preferences and uncheck the box marked

Mac Pro 2008 with 8800 GT, hard freezes with screen savers/OpenGL. You too?

I have been experiencing random intermittent hard crashes of my "early 2008" model 8-core Mac Pro. Now I have finally found an easy reproducible test case (see below), and hope others will try it and post the results. This is a video-driver related crash that I have now duplicated with two different video cards.
The symptom is that my screen randomly freezes. The mouse moves, but there's no way to use the Mac[1]. Holding the Power button to force the Mac to shutdown is the only way out.
Usually, this occurs when I get to my office in the morning, or after the gym. That's because the screen saver is running. I found that the screensaver, other OpenGL/3D type applications, are what triggers this bug.
The bug seems to be with the graphics driver. Immediately before the freeze, messages like this are printed in the system log:
Mar 26 18:34:14 Mac-Pro kernel[0]: NVChannel(GL): Graphics channel exception!
status = 0xffff info32 = 0xd = GR: SW Notify Error
Mar 26 18:34:14 Mac-Pro kernel[0]: 0000000c

Mar 26 18:34:14 Mac-Pro kernel[0]: NVChannel(GL): Graphics channel exception!
status = 0xffff info32 = 0x3 = Fifo: Unknown Method Error
Other errors like these also appear (the actual log output volume is too large for this forum):
Mar 26 21:15:15 Mac-Pro kernel[0]: NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0x6 = Fifo: Parse Error
Mar 26 18:34:14 Mac-Pro kernel[0]: NVChannel(GL): Graphics channel exception! status = 0xffff info32 = 0xd = GR: SW Notify Error
Anyway, finally I found on another thread about a similar issue[2], a recommendation to run Folding@Home program to trigger the freeze. They were talking about another Mac model, but sure enough, it triggers my problem every time. I downloaded the client[3], installed it, and then launched the app which gets put in the Applications folder. It doesn't even finish bouncing once in the dock before the Mac Pro freezes.
This is not a bug specific to Folding@Home; juding from the log messages and the effect, this is exactly the same crash that is intermittently triggered by the default Mac OS X screensavers (I use Arabesque, but I think any OpenGL screen saver does it). It's just that running Folding@Home is an easier way to trigger the bug than leaving your screensaver running for hours.
So, that is pretty unfortunate, right? I mean, not only can my new Mac Pro not sleep without losing all unsaved data (yes, I have the reboot-instead-of-wake problem[4], too, but that is another issue...) but it also crashes at random whenever the screen saver runs for a while, or somebody uses OpenGL programs. I have set my machine to never use the screen saver, but still.
So, first and foremost, my question for other 2008 Mac Pro owners with the 8800 video card is: does your Mac puke all over itself when you launch Folding@Home?
I just found it a little bit hard to believe that every Mac owner of the most expensive new Mac and the higher end video card will have these crashes. It could be, but it seemed far-fetched. So I tried some troubleshooting:
a
1.) I considered that I had a bad video card, so I got another GeForce 8800 GT and installed that. Still crashed.
2.) I disconnected my second monitor, and tried it with only one monitor. Still crashed.
3.) I booted from the pristine boot disk my Mac shipped with (10.5.1). Still crashed.
4.) I reduced the resolution on my 30" Cinema display to 800x600. Still crashed.
5.) Just to stave off the usual chorus of "try zapping your PRAM" posts, I zapped the PRAM. Of course, this did nothing (I don't think this has really fixed a problem since the 1990s...). Anyway, it still crashed.
6.) In doing all these tests, I disconnected all USB/FireWire peripherals.
7.) My Mac is totally up-to-date with Software Update as of Thu, Mar 27, 2008. Mac OS X 10.5.2.
I don't want to return this Mac to Apple; it is wicked fast and that really helps me with my work. But, the frequent crashing really is a productivity-killer.
So: does every 2008 Mac Pro owner with an 8800 GT have this problem?
(Note: there are lots of similar problems with other Macs and the new Mac OS X 10.5... I hope to specifically address this particular model and crash in this thread.)
If not, I will go to the next extreme step: pulling out some of my RAM. I have 12GB of RAM, and it all seems to work fine, no parity errors or anything. But I know sometimes problems don't happen unless there's "too much" RAM, "too high" resolution, and so on. But I would like to hear from others before I go banging on my precious DIMMs and riser cards.
Thanks for any information!
The next step will be to determine if this is just another unfortunate defect that affects ALL 2088 Mac Pros (in which case I would want to keep my fast Mac and wait for fixed drivers), or if perhaps just a subset of them have defective video cards that cause the driver to crash in this way (in which case I would want a replacement).
---------- NOTES: ----------
[1]: I can connect via SSH on the command line to the Mac. However, the GUI environment seems borked; opening apps or trying to gracefully quit them via AppleScript either does not work or really hard freezes everything, such that SSH no longer works either.

Hello guys, thank you for the replies.
I do have more data at this point.
ujeezy: Those posts on MacNN and others like them did give some clues.
Jon BWFC: I think you are (partly) right that it's (partly) an issue with the driver. But I have confirmed with a fair degree of certainty in my case that it is a hardware issue too, likely with the video card and not the Mac Pro itself.
cmcom: I think it sounds like you problem is different than the one we're talking about (although who knows, the driver could be causing that too). The freeze we are seeing locks up the whole Mac, and no application crash report is produced.
I had another GeForce 8800 card, so I went through some exhaustive troubleshooting. I tested each card, installed in each of the 16x slots, booting from either my normal 10.5.2 boot disk or a clone of the pristine virgin system disk that shipped with the Mac, and tried to see if the Mac would crash.
Unfortunately this was harder than it seems, because:
a.) both my GeForce 8800 cards appear to be defective, but in different ways (see [1] and [2] below)
b.) In my testing, I thought I was seeing the crash sometimes, but later I discovered that there are different ways to make the Mac crash like this. That is, there are bugs in Mac OS X 10.5.x (probably in the NVIDIA driver) that cause similar crashes, and these bugs occur on all Mac Pro units and even other Mac models, without any hardware defects. Unfortunately, the Folding@home exercises one such bug.[3]
So the upshot is, all those times I was using Folding@home to test this issue were bogus, because Folding@home crashes any Mac Pro with the NVIDIA card, and crashes MacBook Pro machines with NVIDIA chips as well.
Argh! So I had to retest. It took a couple of days but I found another reliable way to crash my Mac Pro, more quickly than just leaving the screensaver on for a day or two: run this OpenGL virtual fish tank simulator[4] for 2-3 minutes. Unlike the Folding@home test, this did not crash any of my other Macs, and after exhaustive testing I found that it ONLY crashed the Mac Pro with one of the GeForce 880 cards installed, and not the other one. This was regardless of what slot it was installed in or what boot disk was used.
Whew! So, I concluded that indeed, there is a hardware defect in one of my GeForce 8800 cards which causes the machine to lock up. [2]
What made this problem much harder to deal with was the fact that Mac OS X (specifically the graphics driver parts of the OS, perhaps NVIDIA-specific) crashes with these same symptoms in other cases too. Like when you run Folding@home, or in some of these cases people are talking about with their MacBook Pro machines.
So, when there is a bona-fide hardware defect, it is really hard to isolate. (It took me like four days.)
The thing is, the defective NVIDIA card that crashes the Mac[2] was a REPLACEMENT card for the 8800 card that shipped with my Mac. I called Apple about the video artifacts I was seeing and they replaced the card.
I am now running the original card (and suffering the ugly video artifacts, but no crashes). At my own expense, I ordered an ATI card (the RADEON HD 2600 XT) and I will install that.
I hope someday to have my Mac work without graphics glitches or crashes. For now, operating (mostly) without crashes will have to do.
The original problem with this Mac continues, though: the video doesn't work correctly; it starts displaying visual artifacts after 1-72 hours of use[1]. That could either be because:
a.) a hardware defect in that video card
b.) a software problem with the driver/OS
c.) a hardware defect in the Mac itself
I strongly suspect A, but hopefully my buying a different card and testing with that will help further isolate what is wrong.
I am marking this thread "solved" because the specific issue I originally posted about has been resolved: the GeForce 8800 card causing the crashes is defective, and using another card fixes that issue.
[1]: The original GeForce 8800 card that shipped with my Mac Pro exhibited annoying-but-not-deadly video artifacts, which can be seen here: http://masonmark.com/wp-content/uploads/2008/04/bogusvideoartifacts.jpg
[2]: Apple replaced the video card, and that is when my deadly video-corruption-plus-frozen-Mac crash problem began. A screenshot example of that problem can be seen here: http://masonmark.com/wp-content/uploads/2008/04/crashedmac_pro_akashitball.jpg
[3]: The red herring in this case was the Mac OS X bug (seemingly specific to NVIDIA-equipped Macs including Mac Pro and MacBook Pro) that causes a very similar full system crash. This bug can easily be triggered by running the Folding@home version "6.10beta2" demo application. That is a serious bug, and since my employer is a Mac software company I reported this bug to Apple via the official channel. It is Apple bug number 5830772.

I have a mac pro 2007 model. It appears I have a corrupted sector on my the hadrive tha has my operating system. If I use the install disk that came with is (Tiger) can I still get my lion back.

I have mac pro 2007 model given to me, I updated it to lion about six months ago, and I do not have a time machine.
Lion stopped loading before I get to the login screen,
I tried all the tips, doing a option/shift/v. I noticed several fsk_dsk errors that it could not fix on my boot drive.
Restore would not work either. The only physical copy I have is the install disk that came with the mac. I think it is Tiger.
If I put this operating system on will I be abel to upgrade it to lion, and if so will I have to pay again?

The Lion Recovery Partition has its own index. Your Macintosh HD partition is the one with the troubles.
If Disk Utility cannot fix it, you may need to apply different Utilities, such as Disk Warrior.
Some readers suggest that the best disk repair is to erase the drive and restore it from your Backups.
This might be a good time to consider getting a new drive to have on hand. This would allow you flexibility in copying, fixing, and (if needed) replacing the drive with the problems.

Belkin Bluetooth not working in Mac Pro 2007

Hi,
I've got a Mac pro 2007 and bought a Belkin Mini Bluetooth adapter via the Apple Store (http://store.apple.com/nl/product/TW622ZM/A?mco=MTY3ODQ5OTY). I was hoping if I bought something from the Apple store It would work.
The mini adapter seems to work, Look at screenshot https://picasaweb.google.com/aseesink/Bluetooth#5598441276491332930 Apologize for the dutch screenprint, but the mark before "Detecteerbaar" can be translated by "detectable".
But if I look at the system preferences I see this: https://picasaweb.google.com/aseesink/Bluetooth#5598441278085536498 Translated it means Bluetooth is disabled. To use bluetooth you need to enable it. But both checks are grey and I cant change anything in this screen.
I did a check (without the belkin mini bluetooth adapter) on my Mac Book and it detects my Nokia telephone.
Using the Belkin mini bluetooth adapter in my Mac Pro it does not pickup any bluetooth signal.
I also tried to do a PRAM reset in my Mac Pro, but that doesn't change anything.
In the system overview (about this mac) https://picasaweb.google.com/aseesink/Bluetooth#5598442444721135026 it looks like the adapter is working. But from my experience it is not working.
Is there anyone else who got this adapter working? Would love to use my magic mouse with it.
Thank you in advance for helping.
Andre

Problem solved!
I just found an interesting article here: https://discussions.apple.com/message/13263724#13263724
The part with bluetooth explorer worked for me.
I can see all my bluetooth devices now including my magic mouse.

HT1338 I own the Mac Pro Desktop with the older OS X 10.5.8. Can I upgrade to a newer version?

I own the Mac Pro Desktop with the older OS X 10.5.8. Can I upgrade to a newer version? Will it affect my docs etc currently stored on hard drive's? How much will this cost?

If you have a 2006 or 2007 model you can upgrade it to Lion - 10.7.x. If it's a 2008 or later model you can upgrade to the current version of Mountain Lion. Doing so requires Snow Leopard 10.6.8:
Upgrade Paths to Snow Leopard, Lion, and/or Mountain Lion
You can upgrade to Mountain Lion from Lion or directly from Snow Leopard. Mountain Lion can be downloaded from the Mac App Store for $19.99. To access the App Store you must have Snow Leopard 10.6.6 or later installed.
Upgrading to Snow Leopard
You can purchase Snow Leopard through the Apple Store: Mac OS X 10.6 Snow Leopard — Apple Store (U.S.). The price is $19.99 plus tax. You will be sent physical media by mail after placing your order.
After you install Snow Leopard you will have to download and install the Mac OS X 10.6.8 Update Combo v1.1 to update Snow Leopard to 10.6.8 and give you access to the App Store. Access to the App Store enables you to download Mountain Lion if your computer meets the requirements.
     Snow Leopard General Requirements
       1. Mac computer with an Intel processor
       2. 1GB of memory
       3. 5GB of available disk space
       4. DVD drive for installation
       5. Some features require a compatible Internet service provider;
           fees may apply.
       6. Some features require Apple’s iCloud services; fees and
           terms apply.
Upgrading to Lion
If your computer does not meet the requirements to install Mountain Lion, it may still meet the requirements to install Lion.
You can purchase Lion by contacting Customer Service: Contacting Apple for support and service — this includes international calling numbers. The cost is $19.99 (as it was before) plus tax. It's a download. You will get an email containing a redemption code that you then use at the Mac App Store to download Lion. Save a copy of that installer to your Downloads folder because the installer deletes itself at the end of the installation.
     Lion System Requirements
       1. Mac computer with an Intel Core 2 Duo, Core i3, Core i5, Core i7,
           or Xeon processor
       2. 2GB of memory
       3. OS X v10.6.6 or later (v10.6.8 recommended)
       4. 7GB of available space
       5. Some features require an Apple ID; terms apply.
Upgrading to Mountain Lion
To upgrade to Mountain Lion you must have Snow Leopard 10.6.8 or Lion installed. Purchase and download Mountain Lion from the App Store. Sign in using your Apple ID. Mountain Lion is $19.99 plus tax. The file is quite large, over 4 GBs, so allow some time to download. It would be preferable to use Ethernet because it is nearly four times faster than wireless.
     OS X Mountain Lion — System Requirements

      the Source entry field.
6. Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.

Mac Pro 2007 can't upgrade to Yosemite

Hi
I am unable to upgrade to Yosemite. Is it possible or do I have to give away my Mac Pro 2007 and get a new one?
Please advice.
Thanks!

Start here:

After download and before running do some housekeeping:
Make a Lion installer (this is for flash but I used a small partition on another disk drive to be faster)
http://liondiskmaker.com/
I recommend installing on another drive, formatted with Lion Installer.
Now would be an excellent time for an SSD. Other than using a 2.5" adapter don't feel there is anything special EXCEPT to install TRIM Enabler.

The SSD was the biggest improvement in 8 yrs. The XP941 would be faster and leave you with 4 drive bays.

Is the only PCI device that boots all Mac Pro models, does not use a 'controller' only an adapter to use M.2 style in PCIe (and unique to Mac Pro that it will boot while PCs X99 still have new BIOS our 8+ year old EFI works, something that cannot be said for Sonnet Tempo Pro SSD card and others).
Just a hint and push into the world of SSD

Is my mac pro compatible with mountain lion?

Is my mac pro compatible with mountain lion/ 2 x 2.66 Ghz Dual core processors?
Any help would be appreciated. Thanks

And FBDIMMs which use to cost $300+ for 8GB can now be had for... 2 x $34.
I paid $300 2 x 512MB August 2006,, then 2 x 1GB $400 March '07
So as long as you only need 16GB you are safe, it is when you need 4GB, or the rare 8GB FBDIMM and 32GB or more, that yes, time to part ways and get a system that supports cheaper DDR3.
Except, right now, 10.8.2 'broke' support for more than 64GB and there were people depending on and using 96GB. Or that more than 48GB also 'broke' the Apple Pro RAID card; a card that still does not support 3TB drives. 10.8.2 does though provide support for more current Nvidia cards (10.7.4 also showed support just not for GTX 6xx series). 3rd party graphic support has always been a weakness, until now.
Apple Mac Pro is a workstation. Except when it is not. It is still not clear how they missed these things.
What 32-bit EFI won't get you is 64-bit kernel mode and abilty to fully use more powerful graphic cards or memory addresses for a single process beyond 4GB or graphic card support with more than 2GB (and 2GB use to always fail in OS X in the past).

Mac Pro 2007 No Power to Hard Drives

While changing hard drives in my Mac Pro 2007 (model 2,1) today, I apparently shorted something out and there is no longer power being provided to any of the hard drives or the super drive. On first boot attempt, the fans went into over drive and I smelled something burning, so I quickly turned it off and reinstalled the original drive.
I am able to boot up off a Yosemite installer USB flash drive and run Disk Utility - confirmed that none of the disks are visible. Everything else on the computer seems to be running fine.
Does this sound like a power supply issue or I have a fried something on the main logic board?
Any help is greatly appreciated!
