Just downloaded mountain lion to my iMac, all correct specs (memory, etc.).  Upgraded from snow leopard 10.6.8.  All went smooth until the installation was complete.  The start-up wheel never stopped spinning; waited at least 20-30 min.  So I shut down the computer, and once I restarted mountain lion launched fine.  However, now I get the colored spinning wheel of death (WOD) with every operation, and the computer runs like molasses.  Even the simplest task like moving a file on the desktop from one location to another gets the WOD going, and takes forever.  Any ideas?  Can I reinstall mountain lion and try again?


iMac, OS X Mountain Lion (10.8.2)

    You can try a safeboot  and see if it sorts any problems then restart as normal.

     

    Yes you can hold the commad -R  on restart to get to Recovery and reinstall ML on top of what you have,

    Thanks.  I read on another thread that Sophos anti-virus can cause problems.  Just uninstalled, and problem gone!  But thanks for the links to safeboot and Recovery.  Will come in handy.  Cheers.

    SafeBoot would have given us this clue-  third party interference.

     

    Sophos anti-virus Always problematic on a Mac,  as with 99% AV out there.

     

    I am glad you got it sorted.

     

    Good computing !

    Another follow-up if you don't mind.  Do you think performing a "hard shut down" with the on-off button after the installation was complete had any impact on the installation?  Recall after the installation was complete the start-up wheel wouldn't stop spinning and launch mountain lion, so I performed a hard shut down.  Mountain Lion seems to be working fine, but just always concerned about hard shut downs.  Is there another way to shut down using a safer method if your computer freezes or have chronic WOD?

    No that is the best you can do in that case. It should recover itself just fine under most all circumstances.

     

    That is the standard protocol

     

    cheers to trouble free computing !

    Yes, quick search indicates no other way if your computer is stuck.  But I just read this as a safe guard:

     

    "After a hard reset, the system will not perform any automatic diagnostics such as checking the file system for inconsistencies, so you might consider taking the initiative to perform these checks yourself the next time you turn on the system. One easy way to do this is to immediately boot into Safe Mode by holding the Shift key during the next start-up, which will run a drive verification and repair in addition to other maintenance tasks. When the system finally boots, log in and run Disk Utility's drive verification to check the hard drive for errors an additional time, and if there are no problems, then restart normally."

    Good one.  Can't say I have ever done this however. In almost two decades of Apple/Mac.

     

    I would suspect a second re-boot sorts this out.
