I can't use any of this information as iCal will not even open on my Mac. It just has an error log.

I cannot open iCal on my Mac. I simply get an error log. I try to "re-open" and the same error log displays. I've turned off the cloud. I've turned off my iPad and iPhone. I've re-started my computer.

iMac, OS X Mountain Lion (10.8.2)

Go to your Home/Library/Preferences folder and move the com.apple.iCal.plist file to the Desktop. Then try launching iCal again. If there's no change you can move the preference file back.


Remember that in Lion and Mountain Lion the Library folder is now invisible. To make it permanently visible enter the following in the Terminal application window: chflags nohidden ~/Library and hit the Enter button - 10.7: Un-hide the User Library folder. Then it will be eashy to find and move the iCal preference file to the Desktop.

Open the Users folder, then your home folder (which will be you admin name) and then the Library folder. The Library folder you see when you open Macintosh HD is NOT the correct library folder.


The screenshot I posted is what you see when you open the Macintosh HD icon and then the Users/Home folder/Library icons.
