first the specifics: I have a MacPro: Version 10.6.2 for OSX I did the latest update that showed for Safari. It went to reboot and just sat there and hung. I waited for 10 minutes, then manually restarted the Mac. It came up, but then when I went to open Mail, I got an error that it couldn't open. I then clicked on ok, and tried to open another app, and it wouldn't open. I tried with several apps with the same result. I downloaded the MacOSXUpdCombo10.6.2.dmg and ran it with no problems, and the Apps will still not open. Any idea's?
