I have a late 2011 MacBook Pro 15", 16gb ram 2 hard drives SSD in primary and swapped my DVD for the 750gb that was installed when I ordered it. It has been rock solid since I purchased it, never an issue. The ram and hard drive arrangement has been in place for over 6 months.


While plugged in, Saturday afternoon I upgraded to 10.8.5 and after it was completed shut the lid and slept the laptop. Used it for maybe 20 mins on Sunday morning and shut the lid to sleep it.


On battery this morning, opened it this morning to weird graphics gitches and an offset display, it locked hard after I entered my password. Reboot, choose not to open any apps that were open previously, and it crashed as soon as it hit the desktop with a kernel panic. Rebooted again and it seemed to work fine for a 5 minuits. I opened my daily news reader, NetNewsWire and it locked again. Shut it down,plugged it in then reset SMC and PRAM.


The FileVault preboot password screen has faint horizontal blue lines goines across the whole display. When I enter my password, the Apple logo appears and then it just stops on a grey screen. Safe mode and recovery both end on a black screen - no display but the back light is on. But the fans start going full blast and the bottom is HOT. Left it off for 30 mins but no change when I tried it again.


This has to be related to some part of the update - no other explaination. Switching from integrated to discrete triggered it I think. Now my poor mac is toast.


I have a genius bar appointment tomorrow afternoon (earliest I was able to get).


Any insights or people experiencing similar problems? Any other troubleshooting I can try on my own? I'm really really hoping Apple doesn't want me to pay for a new logic board. No Apple care.

MacBook Pro, Mac OS X (10.7.3)

    May also be resolved by


    • Repairing the disk
    • deleting your /System/Library/Extensions/BootCache.kext file and letting it be recreated slowly during startup.


    This is dependent on what Disk Utility says.

    Don't jump ahead and worry about the windows partition yet Let's find out what happens first.

    Book a genius bar appointment and carry it instore as its probably better diagnosed in the flesh.


    May be Hardware related. Not necessarily yet. The Diagnostic tool can help identify some hardware problems. Boot using the D key before the startup screen.

    Same thing here. Early 2011 Macbook Pro. After the 10.8.5 update, upon booting, the screen was shifted to one side with a big black line down the middle. I changed the resolution, the system froze. I rebooted to a white screen, the computer got very hot, fans running at full blast. I shut it off, tired to boot into safe mode, no luck. Recovery mode, no luck either. Tried to boot from my Time Machine backup, nope sorry. I keep getting to the same spot in the boot process where, I'm guessing, the graphics card switches over from using the Intel HD Graphics 3000 to the AMD Radeon HD 6750M.
