All was working fine in 10.8.1 update to 10.8.2 killed the Graphics Card for me.
Same with 10.7.5 update to 10.7.4 - Update killed GPU.
I am back to 10.7.4 and 10.8.1 for my System.
Dell Latitude E6420 - i7 2720QM - NVS 4200M
10.8.2 is urgently required as this will be the minimum requirement for the next tons
off applications and features...
Any ideas?
Save boot works btw.
