Ok, so I've just received my new quad core mac mini and and as I usually do, I like to re-jig things a little which involves me doing a fresh install using the latest 10.8.2 image downloaded from the mac app store. When I've come to boot from the USB stick, I get the circle with diagonal line through it. I've tested the USB stick on another mac I have and it works flawlessly... I originally guessed it was something to do with this latest machine being a custom build of 10.8.2 (later than the one on the app store), but it was actually running 10.8.1 On the phone to AppleCare as I type this because my Internet speed is painfully slow! I'm not expecting them to be able to help much but would at least like them to be aware of it and have it documented so they can sort it out. Surely I'm not the only one who re-jigs things when getting a new mac?! Can someone change the title of the post to say "Late 2012 Mac Mini cannot boot from 10.8.2 boot stick" please? Thanks!
