mac os x mountain lion finder freeze
Ever since I installed Mountain Lion on my late 2008 Macbook Pro, I've had several episodes where the Finder became unresponsive after doing certain tasks like emptying the trash. Force quitting the Finder or relaunching it results in the Finder and any external drives disappearing from my Desktop, so I am forced to power down my Macbook Pro then restarting. I've tried using Disk Utility to repair permissions, but that hasn't alleviated the problem. Should I try to do a clean install of Mountain Lion then?
MacBook Pro (15-inch Late 2008), OS X Mountain Lion
