Since installing 10.8.2 my MBP, if i leave my laptop running and walk away.. It shuts the display down but the fan keeps running.. When i return to wake it, it will not wake up just sits with a black screen..'


i have to power cycle my laptop to be able to use it again..


Is anyone else experiencing this?


it's a late 2009 MBP

MacBook Pro, OS X Mountain Lion (10.8.2)

    Exactly same problem, and the processor seems to be going full bore, as the case is hot and the fans are blasting. Tried reinstalling the combo update, repairing permissions and even disabling the hibernate function using the terminal command, all to no avail!!!

    This is a show stopper, as I have my MacBook Pro set up with a docking station and don't want to turn it off every time I walk away.

    Is there a set of instructions for reverting to 10.8.1?

    Exactly the same problem on my brand new rMBP. I wake up last night to the fans screaming full speed, and it wont wake itself up. not to mention the battery life is worse than what it was before the update. Not happy at all.

    and now it also freezes at least once a day.. which it never used to do!

    I'm having same exact issue, since installing 10.8.2. After putting it to sleep, it will wake perfectly fine within a few minutes or so. But at some point, after sleep's been on a while [an hour, 5 hours, overnight], the laptop's fans start running, it gets hot, but the screen remains black - and it won't wake up without a complete power down and start up.


    This is a HUGE issue, as it's frying my machine whenever sleep kicks in...


    Please advise

    Exactly the same issue here with my MBP 13" (Mid-2010) after 10.8.2.

    Does this have something to do with the new Power Nap feature?

  • Goofyfaces Level 1 Level 1

    I am experiencing the same issue on my iMac. When it goes to sleep at night, I cannot wake it up in the morning. I have to restart the computer.

  • Risko Level 1 Level 1

    Same issue here with MacPro. Can't wake it up with a mouse click or keyboard hit. Have to perform hard-shut down to move forward.

    Yep, MBP mid 2009 here and this issue appeared with 10.8.2 pretty annoying, but hopely Apple will solve this one. Seems like it's pretty common:


  • schamm Level 1 Level 1

    Some issue here on a MBP with 10.8.2 installed.

  • JP Barbosa Level 1 Level 1

    Same here with my MBP after 10.8.2. Unbelievable... Looks like Apple test new OSX releases only in their brand new computers.

  • fairweam Level 1 Level 1

    Having the same issue after installing 10.8.2 on my late 2008 MBP.

    doesnt even look like that is the case. my rMBP is as new as they come, absolute top of the range.. ever since the 10.8.2 upgrade i cant put the thing to sleep. (Lucky it starts up in 7 seconds anyway)

  • CrHerm Level 1 Level 1

    Same story here. Late 2008 Macbook Pro, no problems with sleep until now.


    My setup: MBP connected to external monitor via mini Displayport->HDMI, with USB hub connected to mouse, keyboard, and external hard drive.


    Since the 10.8.2 update, whether I put it to sleep manually or let it go to sleep on its own, when I come back the fans are running, the screen is black, and it doesn't respond to any keyboard or mouse commands. When it's awake I generally have the fans set to 4500 rpm using smcFanControl, and when it's locked up like this, they're running slower than that but faster than the quiet 2000 rpm default.


    I have tried disconnecting the monitor and USB hub, and the problem persists.

    Same issue here...


    iMac 2.93 Ghz Intel Core 2 Duo, 4 GB Ram.  Worked fine before 10.8.2.  After install, computer won't wake up after it's been asleep for an extended period of time.


    Called Applecare, they had me repair disk permissions...that didn't work.
