Hello, I have had a very stubbern problem with my '09 mac pro waking from sleep... it doesn't very well or at all. Researching again I find this apple discussion: https://discussions.apple.com/thread/4326602?start=90&tstart=0 The post by "Bonfire" explains my problem pretty much exactly. I was running both the stock and the ATA video card. I tried the updated driver he suggested: NVidia Driver Update: http://www.nvidia.com/object/macosx-304.00.05f02-driver.html but now I get some sort of sleep cycle when trying to put my mac pro to sleep. It goes dark, and the fans spin up, and it wakes, repeat. I took out the nvidia stock card, just running the ata, and it still does the same thing. What should I do? F(*&(*&*(&*( APPLE PRO SUPPORT! any suggestions? thanks, r.
