just downloaded and followed instructions installing mavericks on new macbook air 13 and 2009 imac 27 - same result: installation fails, failing to reboot with following message: your computer resstarted because of a problem... followed by screen with following message - "panic (cpu 1 caller - and later Mac OS version: not yet set..." does someone have a similar problem? What to do? Both updates from Mountain Lion..
Thanks
ah man.........I fear this might happen......my 15" rMBP can't even handle the latest 10.8.5 Supplemental update without nearly bricking. I might just finish the DL wait and see.
