Has anybody started experiencing sudden freezing and the spinning medicine ball since upgrading ? I have to do a hard reset every time this happens which is severl times a day now since upgrading .
MacBook Pro (13-inch Early 2011), OS X Mountain Lion
I have very similar symptom as you described, except that I get complete lock up including the mouse pointer whenever I try to open a big Quicktime file or access HD youtube movies. Quicklook of movie files does the same thing and fails to show the movie at all. Lock up would go away if I wait long enough, say 30sec to 1min, but it still drives me nuts. I sense that GPU of my 2010 Macbook Air doesn't want handling big graphics load.

What I've found is that it gets triggered by pretty much anything that puts a load on the graphics processing i.e. video playback streaming and local playback, games (i.e. Starcraft 2), etc.. Essentially you'll running your video or game for a time (seems to be random) and the system locks up. In my specific instance the freezing can be triggered sooner the more I tax any portion of the graphics system. ..
Ok. It seems that in my case the obsolete 'Perian' extension may have been the culprit. Once I disabled it and restarted the MBA, QT movie files seem to open without any lag or lock up. I won't declare that it fixed everything yet but if anyone still has perian installed under Mountain Lion I recommend disabling it.
Okay... seems as though 10.8.1 has resolved the issue for me. Thank goodness...
I just installed Mountain Lion last weekend and now our iMac is a total disaster. Most of the apps either don't open at all or are really slow to open. I even have to wait several minutes for the spinning beachball to stop after opening System Preferences. Anything I click on inside SysPref starts the spinner again and hence I have to wait even more to check things. All the sound devices have disappeared in SysPref, including the Internal Audio, even though the computer makes the usual startup sound when it boots up. Someone advises resetting PRAM, but that does not work either. The computer just keeps re-booting. If any of you know another way to reset PRAM, please let me know. I have already done the SMC reset. My system and therefore my work has been dead in the water for three days now, so I appreciate any help you can give.
OS X is damaged. Press Command and R keys in boot and reinstall
For the last 2 weeks I have done nothing but isolate and trouble shoot programs(at the recommendation of Applecare engineers) to try to figure out why the freezing is happening . In the last 24 hours , I am starting to lean on the idea that my Tweetdeck application is what's causing the freezing . I am running V38.1 . I haven't opened the app and I haven't frozen since I started . I may uninstall and then reinstall after trying this for another day or so .
System Preferences > Energy Saver > Computer Sleep > Never
This has been the only thing to work for me. Ever since update to 10.8, greater than 6 freezes a day and hard resets. 24 hours with out a freeze since changing this setting. Hope this helps... it appears there are a slew of bugs.
Magnum , when you're just doing your normal computer stuff , are you running a couple of apps at the same time? What I have found is that some of the apps I've been using are flawed or corrupted and what I've done is uninstall them and then reinstall . My problem was Tweetdeck V38.1 , it's the older version but I like it better so I kept on using it . You might want to try something similar as far as narrowing programs down that are running when it's freezing . Let me know .
And I got rid of "Perian", an old version of ClickToFlash and LittleSnitch. Now the chrashes are down to a minimum.
Still the system is slow and I also had troubles without any third party software but now my computer is a least usable again...
I've noticed that both MBP and my iMac are both slower with ML installed . I'm not thrilled about it .
I actually shut down all programs that were running and put the computer to sleep... soon after waking it froze when opening Safari. I even closed down all running 3rd party apps in the menu bar prior to. I'm back to normal without the computer going into sleep state. No freeze in a day with multiple programs/apps running (Safari, iTunes, Parallels, Handbrake, and all my usual 3rd party apps running in the background/menu bar). BTW, Perian is running as well as Click to Flash and 1Password. Let you know if it stumbles but got my fingers crossed.
I solved a similar problem that occurred when I installed Mountain Lion on top of Lion a couple of weeks ago. Mountain Lion turned into a Sloth immediately after the install. It not only began generating the spinning beach ball whenever I did anything, but it prevented me from opening SysPref to make any changes, all of the sound devices disappeared, I could only open three resident apps and none of my installed software would open, i.e. Final Cut Pro, Logic, Soundtrack, Avid Symphony 6, Maestro 2, etc.
Well, after waiting for tech support to come up with a better plan than a full system reinstall, I decided to take matters into my own hands. I ran a simple app written by a discussion forum user called EtreCheck that basically finds corrupt sys files that failed to install. I then searched the web to find out what these files were for and discovered that they were fragments left over from Snow Leopard. The moment I deleted the first two, all of the sound devices reappeared, the spinning beachball disappeared, I could open every app for the first time in ML as well as SysPref. Mountain Lion basically came to life for the first time! What also reappeared in SysPref as an audio device was a Euphonix Monitor device that I thought I had removed weeks ago. One of the failed file sys files appeared to be a currupt audio driver. When I removed that one, Maestro 2 which is the software behind Apogee's Ensemble audio interface came to life as well. It was the only installed software that would open in ML, but it was nothing but a large gray panel without any faders, knobs, buttons or mixer. To make a long story short, Mountain Lion is now working better than Lion did. You might want to give this a try.
Would you mind posting your EtreCheck so that I can compare with mine?
I'm having the same problem. My system has locked up 4 times. All 4 times I get the same log message regarding GPU restart:

Anyone have any info on this?
Are you talking about posting the app itself or the results page that was generated by the app? If you are asking for the latter, I am not sure I still have it for I believe I deleted it after deleting the failed files. Unfortunately, running the app now returns a clean page with no failures in red, but I will check my folders to see if I may have saved it somewhere, assuming that is what you are asking for. Have you already run the app and if so, did it reveal any failures. Let me know.
BTW, it is not my app, but rather someone else's in the discussion group who created it to help troubleshoot a different issue he was having.
