Ever since updating to Mountain Lion, my iMac freezes

Just recently, my iMac started freezing (color wheel turns and there is no mouse control). This happens particularly in Outlook but also in Safari. I don't know if the processors are grinding away at something or what I'm doing is being compromised by a bug or virus.

iMac, Mac OS X (10.6.8)

The next time you have the problem, note the exact times when it starts and ends: hour, minute, second.


If you have more than one user account, these instructions must be carried out as an administrator.


Launch the Console application in any of the following ways:


☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)


☞ In the Finder, select Go Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.


☞ Open LaunchPad. Click Utilities, then Console in the icon grid.


Make sure the title of the Console window is All Messages. If it isn't, select All Messages from the SYSTEM LOG QUERIES menu on the left.


Scroll back in the log to the time you noted above. Post any messages timestamped during that interval – the text, please, not a screenshot.

When posting a log extract, be selective. In most cases, a few dozen lines are more than enough.

Please do not indiscriminately dump thousands of lines from the log into a message.


Important: Some private information, such as your name, may appear in the log. Edit it out by search-and-replace in a text editor before posting.

Your boot drive is failing, or you have some other hardware fault.

Back up all data immediately, then make a "Genius" appointment at an Apple Store to have the machine tested.

If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to bare metal from any of them.) Don’t erase the recovery partition, if present.

*An SSD doesn't need to be zeroed.
