If you’re reading this post, it’s likely that you own an OCZ SSD and just updated to OS X Mountain Lion. Then BAMMM!! you can’t boot into your shiny OS.
While we’re waiting for OCZ or Apple to fix this, I have an easy workaround to share with you.
- Boot into Single-User mode >;>; hold Command+S after you hear the chime.
- Wait until it stops at the prompt, then type
/sbin/mount -uw /
- Then type this and return
sudo rm -f /private/var/db/BootCache.playlist
- Finally type ‘exit’ without quotes, and press return to boot into your Mac.
- Hoorayyy!!! 😀
Now, next time you do a reboot, just boot into single-user mode again, when the prompt comes up. Press the up arrow key until you find the first command, execute it. Up up again to find the second one, execute, then exit the single-user mode. You don’t have to retype them every time you do a reboot!
Official OCZ announcements will be posted in this thread.
Note: I’ve seen some posts say you need to boot into safe mode and then single-user mode. I find that unnecessary. Steps above work for me.
