I have a Late '09 Mac Mini running OS 10.6.8. When I go to 'Software Update' and attempt an install it doesn't work. I do the install and restart the computer and it just freezes. I installed the Mac OS X 10.6.8 Update Combo v1.1 from Apples site and it didn't solve this issue. http://support.apple.com/kb/DL1399 Any help or advice will be appreciated.
