Mountain Lion and the freezes

Sunday, 26 August, 2012 - sesam

Not that I expected otherwise, but Mountain Lion did naught in fixing the iMac graphic driver freezes that Apple claimed are the result of hardware issues. If anything, the crashes are more frequent, albeit it can just be caused by the fact that it's Summer and with no A/C it's 30°C+ inside.

The freezes are often somewhat more graceful now with a kernel panic message and an automatic restart. After such an event a report is generated and sent to Apple. Not that I have illusions of them taking it seriously.
