10.8.3 update failed

App Store app downloaded the update fine, requested restart, after OK seemingly installed software. Requested restart again. Came up with a dialog box "Update failed, restart the system". After the system restart it lists as 10.8.2, but App Store app now crashes reliably can not retry install or see status. Anyone else with this?

MacBook Pro (15-inch Early 2011), OS X Mountain Lion (10.8.2)

I tried updated to 10.8.3 today and now my macbook pro late 2010 will not start up. I get the gray screen apple logo and spinning circle.


I tried holding shift during reboot, nothing.

I tried cmd R, nothing.

I tried holding option, nothing.

I put my recovery disk in and......nothing, except now I have a recovery disk in the drive and it won't eject. I'm not happy.

Can someone please help me?

Just an update. Tried making my drive available via FireWire and finally yanking the HD from the iMac (put in an exernal case). Used all the HD tools I could find. no dice. The drive was toast. Ordered a new HD from and I'm back in business.


At this point I'm thinking my issue was NOT the update but that my HD had reach EOL.

Also sent feedback to Apple on this issue. 😐


I have a 27" iMac where the update to 10.8.3 is never successful and I'm always presented with a notification and red badge in App Store that I need to update and reboot. I've given up after about 10 times. 😢


I have a 13" MacBook Air where the update was successful, however.


Strange. 😕
