Q: iMac mid-2011 kernel panic
Hello everybody,
Unfourtunately my dad's mac has been a proper headache lately. It all started 2 months ago, when chrome would sometimes crash with an "Oh, snap" message, reinstalling didn't help. After that, came the kernel panics and the sudden restarts. I tried every trick in the book - completly wiping the hard drive, resseting smc, etc. nothing helps. The kernel panics come at random. The computer has been in 2 authorised service providers, and nobody managed to fix the problem - 1 service swapped the hard drive, the other put in a new graphics card, all at our expense. Today the computer came from the second service and it got the panic within an hour.
