Since the wait for the 'genius' appointment is over a week, I've been dabbling myself to try and diagnose an issue on a Mid2010 MBP. Its been running slow as hell and today had its first ever kernel panic. Everything seems to be pointing towards the HDD, but Im conscious it could also be a logic board/connector issue. Tests so far: - Disk Utility, single user mode/fsck and apple hardware test, all passed. DriveDX (utility for checking smart status), shows high CRC failure. Any words of wisdom?
