Well I'm doing a complete OS X clean reinstall after doing a simple OS X install. Unfortunately the freezes kept on coming after the non-clean reinstall. So I took the "burn it to the ground" approach after calling Apple Care (who recommended this approach). I don't know if it was third party software causing the freeze, so I'll run it without installing any new software. I assume I'll have to download Apple's free software that came with the computer? As a back-up I've scheduled an Apple Genius visit in case this doesn't work. Anyone else having issues with freezing. Note the force quit window did not show any open applications not responding.
