OSX upgrade crashes Mac

OSX upgrade crashes Macs- The Inquirer

readers have been finding their Macs hanging or suffering from
post-update reboot blues. The Airport and wired network connections
keeps dropping and there are audio bleeps when users try to restart.

The Mail application refuses to quit, fails to connect or crashes
while attempting to connect to the mail server. And it really hates
messages with attachments according to reports.

The upgrade is self-censoring too. Instead of warning the user that
there is a problem, the system goes mysteriously silent as if there was
no problem at all. Much like the Apple press office when it comes to
bad news.

One user reported that the upgrade made his Imac into a brick,
complete with a white screen which just bleeps at him, which is
probably a wrongly-reported RAM fault.
