Currently Being ModeratedNov 12, 2009 4:21 AM (in response to Joe Penna)I have quite the same problem. I'm not sure, but i think it started when i updated to snow leopard. i can't remember having that problem with leopard!
in my case it's not always when i boot the macpro, but almost everytime when i reboot the mac, or then i try to wake it up from sleep.
if i connect to the macpro via screensharing, i can see that it starts up just as normal.
any help on that would be great!
apple hardware test didn't give me any errors eitherMac OS X (10.6.1)
Currently Being ModeratedJan 3, 2010 3:58 PM (in response to Joe Penna)Hi,
I've this since I had repaired permissions using Onyx.
Sometimes it boot without display, but I know it booted up, cause I've had control on the keyboard and let me shut it down.
And I've to turn the UPS off and try again to get the display working.
Is there a solution for this??8 core MacPro 2,8, Mac OS X (10.5.8)
Currently Being ModeratedJan 8, 2010 6:57 PM (in response to Sonik31)From my tests it is not a graphics card problem per se. It is something that has changed in the OS during an update along the way as far as I can tell. I have two Apple Installed 2600 cards one is working and the other is sporadic as of two weeks ago. My guess is that either the problem could be fixed with an OS update or a firmware update, but since apparently Apple is not going to even acknowledge this problem the only solution may be to buy new cards or a computer?
After an SMC reset and PRAM Reset a few days ago, all my cards are waking for sleep just fine now during the daytime and early evening, but something happens between midnight and 8am every morning while in sleep mode that causes the monitor connected on one of the graphics cards not to wake up - takes several shutdowns/reboots and cycling the monitor power off and on to get it back up - then it is fine for the rest of that day.Mac Pro Dual 2.8GHz Quad-Core Intel Xeon (8-core), Mac OS X (10.5.8), 16 Gig Ram, 2-ATI HD 2600's, Airport Extreme, 4-Internal HDs
Currently Being ModeratedMar 22, 2010 12:12 PM (in response to Joe Penna)I'm having the same problem here. I called to an Apple Authorized center and they told me that are a lot macpros with the same problem. Nobody knows what's is going on. They're tried to replace graphics cards but the problems seems not to be solved.
I've tried everything, reseting, changing displays but its still with the same thing. Once I had video response, but it has stopped when I restart.
WHAT's GOING ON???? A lot of people with this same PROBLEM. I Need to hear something!!!Macpro 8 core, Mac OS X (10.6.2)
Currently Being ModeratedApr 9, 2010 8:42 PM (in response to arthurf2)I'll add my name to this list of Mac Pro issues. My 2600 is acting up too, right after I installed a slew of updates. I changed the card to a new PCI slot, which worked...until I turned of the computer and tried to restart. Blank screen again. I called Apple Care and they said that they hadn't heard of this problem...Mac Pro
Currently Being ModeratedApr 10, 2010 9:37 AM (in response to Girgle)Same issue here.
I've reinstalled 10.5.8 with a whole new kernel, then upgraded to 10.6.3. But four times out of five, this Mac Pro boots to a black screen. I believe the computer is booting all the way up, because I have the front power button set to put the computer to sleep, and when I manually power down the machine using the power button, the Mac will go to sleep first.
- MacPro 2008, 8-core 2.8
- 14 GB RAM
- ATI 2600
Here's what I've tried:
- Reinstalling and updating OS both 10.5 and 10.6
- Pulling all USB and firewire peripherals off the computer -- Mac promptly booted to black screen, so peripherals are not the issue.
I have tried booting to the Apple Hardware Test on my commercial Leopard DVD and Snow Leopard DVD, but the machine will not boot to this (these disks will boot the AHT on other Macs). I no longer have the original CDs that shipped with the Mac.
I too have suspected the video card, but according to previous notes, apparently this is not the cause.
I'm now suspecting a motherboard firmware issue.
Before this, the Mac Pro was having a related issue pertaining to VMWare Fusion, wherein the Mac would occasionally not wake from sleep, logging a VMWare Fusion kernel crash.
For the moment, I'm not shutting down the Mac Pro, just turning off the Cinema Display.
Any solutions, please notify me.

How can the video card be ruled out without swapping for a good one? in my experience swapping RAM, video card, etc is sometimes the only way.
AHT - is only on OEM DVD that came with that Mac model, and not on retail copies of OS X DVDs.
Installing Leopard and then Snow Leopard is generally not needed or ideal. A clean install really is preferable especially when troubleshooting.Mac Pro 8800GT 10K VelociRaptor, Mac OS X (10.6.2), Windows 7 i7 3.2GHz GTX 260-216
