Hi guys! Sunday morning I switch on my MBP and went to prepare breakfast - when I returned to the desk - there was no login screen - the grey boot screen with apple log and small spinning "gear" was still spinning. Took a shower and when I came back - nothing had changed -seems to be stuck at the boot screen. The evening before, there was just a normal shut-down. Before closing, I just ran update from the app store and moved a Lightroom 4 gallery to an external hard drive. I ran Disk utils to scan the main hard drive - there were a few rights on 2 folders "out of order", but easily fixed. The hard drive scan said "no errors" and that the "volume is ok"., I rebooted - but still same problem - no error messages displayed. Any tips on debugging this? Does ML have a "verbose" mode??? Thanks!
