[QUOTE="chscag, post: 947433, member: 46727"] If you don't have a backup that you can restore to, try starting your Mac using Safe Boot. See the following Apple KB [URL="http://support.apple.com/kb/HT1455"]LINK[/URL] If you can get started in Safe Boot mode, you may be able to undo whatever the updates did of left undone when the error occurred. Although it's doubtful that you can recover that way, it's worth a try. Some advice for the future Tarek: Always make a bootable backup prior to updating OS X. Use that 160 GB external drive and use either SuperDuper or Carbon Copy Cloner, or at the very least, Time Machine. The actual space used on the external depends on how much data you have on your internal drive. Regards. [/QUOTE]
