Update 10.8.2 from 10.8.1 fails with MacPro 2009 and ATI HD 5870
I tried to update my Mac Pro 2009 from 10.8.1 to 10.8.2, after the download and install of 10.8.2 my mac completly hang in a white screen mode with broken graphics. No chance to fix that - i nearly tried everything. All hardware is okay, as i went back to 10.8.1 from a cloned drive.
Yes, the configuration of my mac is complex, here is a list:
Mac Pro 2009 2x 2.66 GhZ Quad-Core
96 GB RAM - 3x 16GB + 3x 16GB
ATI RADEON HD5870 1GB
Apple RAID Card installed (with 4 drives raid 5 attached)
Apple Fibre Channel Card installed (2x 4GB Fiberchannel)
Monitor NEC PA301W
Booting from a Crucial M$ 512MB SSD
Again: All works perfectly fine on 10.8.1.... As I went back through a cloned drive.
BUT it`s impossible to boot the machine even from an attached (firewire) clean installed 10.8.2 (i tried that too)
10.8.2 worls perfectly on my the Mac Book Air, no prblems upgrading at all- BUT did anybody know of a bug - especially related with the ATI HD 5870 in an MacPro 2009 ?? I repeat myself, all works perfectly great on 10.8.1 but there is as of now no chance to go up to 10.8.2 without getting a white blank screen.
So please, did anybody had the same problems with the ATI 5870 ? Or with the Apple Raid Card or Aplle Fibrechannel 2 Port Card? Is it the combination within my Mac Pro?
I would really appreciate any tipp, help or support !
Thanks!!!
