the cursor freezes sometimes, but even when it moves I cannot make anything happen with it except Shut Down, the track pad is unresponsive, and the screen is frozen, and sometimes there are some problems with graphics:

This is what happens repeatly before the boot time:

I'm pretty certain it's related to the GPU driver and isn't triggered by anything other than OS X itself (usually occurs for me on my MacBook Air when I hover over the dock.

My iMac with the same exact OS X build does not lock up in the same way, so I believe it's specific to the MacBook line...

My wife uses a macbook air early 2012 with ML and has no freezes... maybe it's the 2011 or earlier macbooks?

...when I reload my MB. As you can see it has been frozen about 6 minutes...at these time just my mouse works, but anything else...then I proceed to reload it.

Experts, What do you think about it?, I'm using ML, this was an upgrade because I was using Lion and never had this problem. Any workaround?

Regards,

Updating to 10.8.1 now. Will post next time I have a freeze 😉

This has happened to me twice now. Same console output that others have posted. Both times while watching netflix in Safari. 2012 13" MBA with Intel HD Graphics 4000 512 MB graphics. 10.8.0

Audio continues to play, but the screen is stuck. Can't forcequit or anything - have to force shut it down.

Aug 23, 2012 6:54 PM in response to Adam Berti

Make another user account, log in to it, see if the same thing happens and let me know.

Aug 24, 2012 7:09 AM in response to sdaza

Exact same problem here. Working on a Mac Mini 2011 (Intel HD3000). Same errors in log file.

Audio keeps playing and the mouse is working too. I've tried a safe-boot but that didn't help.

Updated to 10.8.1 yesterday but didn't work for me. Had the same crash few minutes ago.

I think this problem started when I swtiched to Mountain Lion. I can't remember this happend to me when using Lion.

Aug 24, 2012 8:39 AM in response to Anthony Tomasino

Unfortunately it's not consistent. I'll make a new user account and use it to watch netflix, but it's random so that might not be usefu. Not sure if it's Mountain Lion related or not as I purchased this MacBook Air and went straight to Mountain Lion. Didn't see the issue on my old computer and the curent user has never reported this problem to me.

Aug 25, 2012 10:36 AM in response to sdaza

Go to Applications and open Disk Image. Click on the indented disk drive at the top left hand side, should be called something like "**** 's iMac". Go to the bottom right hand side and select "Verify Disk". Follow the prompts.

It had me restart the computer while holding down R-Command and then reopen Disk Image and select "Repair Disk" seemed to speed everything up and stop the crashes.

Repairing partition or permissions won't solve anything. I did this couple of times. I'm on 10.8.1 and it froze again today.

I've got same issue, I'm going to update my OS but i think it will not help. The freezes are sometimes, most of them when i hover dock icon with browser on (sometimes flash is playing). After freeze i can move my mouse only.

The log is same as all have: Debug info for *possible* hang in MAIN graphics engine

I've got MacBook Pro 13' Early 2011, i5, 8GB Ram, Intel 330 SSD, Mountain Lion 10.8.

Hope for some fixes of the driver...

It was about 3 loong minutes freeze and there is no way to recover, unless reboot it. This is a random situation because I have been working with several Routers under GNS3 and CPUs (4) is working full and it never freezes. The above logs happened when I was doing practically nothing.

Even CMD+ALT+ESC did not work..just my mouse.

Pls Apple experts your diagnostics are welcome and a new fix on release 10.8.2 too 😀

Since updating to 10.8.1 I've had no freezes, but I do know that others have reported freezes. I submitted a ticket with Apple customer support and spoke to someone on the phone today; who recommended I delete the /Caches folder in my Library directory. Apparently this can cause some freezing issues if it gets too full. I've done so, though I doubt it's got anything to do with the problem, things are still running smoothly. I'll report back if I get any freezes.

Oh, the support person also suggested trying to boot up in safe mode and then rebooting the next time it happens.
