With the new POS Mountain Lion, my MacPro has become more unstable than my Windows 7 .... so much so that I'm actually considering going back to my pc.


While using the computer, the entire system will freeze.  Can't click the apple to do a force quit ... the only thing that I can do is a hard turn off / on.


At first, I thought it was Mozilla products causing the crash (either Firefox or Postbox - which is based on thunderbird).  But it really doesn't matter what I'm doing on the computer.  Today, I clicked on the app store and the entire computer froze.  At other times, I've clicked on finder and entire computer froze.  Sometimes I'll be opening up a new program, other times I'm trying to close software - and at other times I'm simply trying to save a file or open a new file.


It just doesn't seem to matter anymore - my macpro is freezing now about twice a day.  I never had this issue prior to upgrading to the new Mountain Lion OS.


Is there anyone out there that has any recommendations about how to either fix this problem or uninstall the Mountain Lion OS?


Thank you.

Mac Pro, OS X Mountain Lion (10.8.2), 12 GB Ramm

    Mountain Lion is typically not that unstable.  What it does say is you probably have something not compatible that is installed, or your machine has other inherant issues that just happened to surface with the install of Mountain Lion.  Is your data backed up?

    OK, see if temporarily booting with no hard drives attached at least solves the freezes.  Having multiple hard drives attached at once can cause issues with asynchronisity of the drives, especially if there are other peripherals attached to the same bus that don't understand Apple's Energy Saver, or other standards.  Simplify.  Also double check each application version's compatibility on making sure all reports are newer than July 25, 2012.  Anything older may not be accurate.  Generally speaking backing up is best done when you aren't doing anything else.  Background tasks can also create issues for Time Machine.  So first simplify and see if the external drives are at issue.

    Steer Mouse and USB Overdrive have both been software that work better with mice than many manufacturer drivers.  See if you can remove the Logitech drivers, and find a compatible version of one of these drivers and see if it works better.

    I am having the same problems you describe, with a very unstable machine that I have to restart many times a day. It was fine before I installed Mountain Lion. I have barely gotten any work done for a month because of it. I am not using anything by Logitech. I don't know how to troubleshoot this properly. When I look at the Activity Monitor, there are lots of items in there, but it's not clear what they are. Everything I have is supposedly Mountain Lion compatible according to the website. Any suggestions on how to figure it out?

    So, I am using Safari, though I do have Firefox installed. I find if I leave my computer on for about an hour without using it, it's a mess when I return, so I am now shutting it down a few times a day. That helps, but is not a solution in my opinion. I am so fed up with it I am ready to throw it out.

    Anyone know if DivX is causing problems with Mountain Lion? I went to About This Mac>More Info>System Report, and clicked Software>Installations, then sorted the list by Source. There were 3rd party items listed for just a few items. DivX was one, and after poking around the web, it sounds like others are having trouble with DivX and Mountain Lion. I removed all DivX files, including the folder in HD>Library>Application Support>DivX, HD>LIbrary>Internet Plug-Ins, and HD>Library>QuickTime. So far, so good. Will see what it's like tomorrow.
