Totally not working!
Just reinstall OS 10.8.3
Install Davinci (first app to clean system, on internal hard drive):
Desktop video driver 9.7 from disk (yesterday Davinci works with this version for about 40-50 minutes).
Davinci can’t launch!
Only Initializing screen.
Uninstall All
Repair permissions.
Install Davinci + today released, newest Desktop video driver 9.7.2
No good!
Do same with ver. 9.7.1 No good too!
I know. Problem is in Desktop driver or in Davinci but not in my MacPro!!!
It worked, not for a long time, BUT IT WORKED NORMALLY ON MY MAC yesterday!
