Barney:
- resetting PRAM executed OK
- I booted to SafeMode OK; but didn't see a progress bar. Logged in OK
- I opened Disk Util from Apps and ran:
- Verify Disk Permissions; this revealed numerous errors
- Disk Permissions Repair, completed OK
I appreciate the guidance. I was on DOS, then Windows, from 1990 to 2009; then
bought my first Mac, this MacBook Pro, in late '09. I'm beginning to recall
directory/registry details from those DOS/Windows years. Choosing to repair
a registry fault on this Mac was new to me; that's why I sought guidance.
Interestingly, my 2011 iMac upgraded from Snow Leopard to Mountain Lion
without faults. Until my MacBook Pro startup glitch, I'd experienced no faults
of any kind with either Mac.
I'll monitor startup/restart activity to see if 'Disk Permissions Repair' resolved
failure to execute full startup without 'exit' & 'boot'.
