    Hi everyone,


    I can confirm that creating a new user solved all my issues.

    Computer now wakes up from sleep without issues. I was able to keep all my apps.

    Please try this and let me know if it worked for you guys too.

    This was the only thing that fixed the problem for me

    Know issue, but to my knowledge no fix yet (permanently).  Does not occur on my MBA 2011 13" i7

    My problem is solved. Was a faulty logicboard (ram slot broken). Had nothing to do with ML. Thank god for the EU warranty rules so after two years it was still under warranty

    I have had the same issue of not waking from sleep, but with an active, black screen. 2011 MBA. Happened after an upgrade to Mountain Lion.


    I've just found my hibernatemode was 7


    I've changed it using this: sudo pmset -a hibernatemode 3


    Will let you know if it makes a difference.

    Okay, i have talk with apple. And they instructed me to downgrade to lion to see if the air also did in there. I tried it and i didnt, i then upgrade to ML and the problem was gone.


    Now i have completly reinstalled ML and the (for now) seem gone.

    Hi I didn't get. We all came from Lion? Do u mean a fresh Lion was required?

  • adib1 Level 1 (0 points)

    Confirmed. I erased the drive and installed Mountain Lion on the blank drive, migrate data and apps back from Time Machine and the problem hasn't resurfaced for the past day.


    On 2011 MBA.

    I have found two things that stop this crash for me on my MacBook Pro Retina.

    1. Leaving it plugged in all the time prevents the crash.

    2. In Terminal "sudo pmset -a hibernatemode 0" stops it completely.


    Obviously these aren't long term solutions, but I'll bet the next update from Apple addresses this.

  • gilberto_rules Level 1 (0 points)

    Yes. After looking at


    man pmset


    to see what sleep mode would be most suitable for my MBA,


    I tried


    sudo pmset -a hibernatemode 3


    and it's working fine now, and has been for the last few days.

    Apparently the update to 10.8.1 solve the issue in my Imac it is sleeping and waking without problems since i did the update.


  • aminasadi Level 1 (0 points)

    No it's still the same for me. Thinking of rolling back to Lion and wait for next updates. U know, this is not my only problem, it also boots up slowly comparing to 3-4 seconds on Lion. my Mac air now takes 8-10 seconds. It's not much but why I should suffer?


    Mountain Lion in my opinion was a waste of money. I only upgraded to see how AirPlay Mirroring works. I was using AirParrot on Lion to stream to my apple tv now I admit that they are both work the same. They both suck on sound mirroring needing some restarts to apps (like VLC) to fix the problem and they both increase the temperature quite fast.


    Overalll, out of 200 new features none of them are of value for me any more!

  • carlos134 Level 1 (0 points)

    Did you try creating a new user account to see if you still have any issues. This was the only thing that worked for me; before that i tried changing the hibernation settings, etc etc nothing worked.

    It has been over a month on the new user and the problem went away

  • aminasadi Level 1 (0 points)

    Well I guess now I know where it originates from. The problem probably is related to iCloud. Whenever you openup the lid it does a refresh or at least it tries to connect to iCloud service. The bad point is, it seems like they are doing that in the same thread as the user interface. That's why screen remains black for a couple of seconds or in the case that you can not type in your password because it's freezed.


    I signed out iCloud service in the setting and removed all of the iCloud related data. Waking really faster now but I should test it more.

    Alternative (and faster) steps to reproduce:



    1. Charge the Macbook Air until the battery is full.

    2. In the Terminal, type:

        sudo pmset hibernatemode 25

    3. Close the laptop's lid.

    4. Wait for about a minute.

    5. Disconnect the power brick from the unit.

    6. Lift the laptop's lid.

    7. Try pressing the keyboard or clicking the trackpad – the laptop won't wake up.

  • ChrisWRX Level 1 (0 points)

    Yes, this is what I am experiencing too.  Here is how I've been able to consistently reproduce the same bug:


    1. Charge the Retina Macbook Pro until the battery is full.

    2. In the Terminal, type:

        sudo pmset hibernatemode 3

    3. Close the laptop's lid.

    4. Disconnect the computer from the charger.

    5. Leave it alone over night.

    6. In the morning lift the laptop's lid.

    7. Try pressing the keyboard or clicking the trackpad – the laptop won't wake up.


    This is the same after the 10.8.1 update.


    The only solution at this point is to hold down the power button until the computer shuts down.  Then, restart.


    Also, I have been able to connect to the computer with another computer while it is crashed.  It appears that the keyboard, trackpad, and screen are not working.  Eventually, it does fully crash forcing the shut down, restart.


    I have been able to leave the computer on over night in hibernate mode 0 without it crashing.  This is where it's set now.
