MBA 11" 2012 model, ML upgraded from Lion
- normal user
Working fine for a week or so. Was logged in as 3. (a regular user), and asleep.
When trying to resume the next day, it showed the desktop and just as it became interactive it crashed with a kernel panic - first one I've had.
At the login screen, where all four accounts used to be visible, now only 1. and 4. are available.
In the users & groups system config dialog all accounts are present and look fine. I can log into accounts 2 and 3, but only if I switch user whilst logged into account 1.
Any ideas? Very confused and I don't know enough about how user profiles are built in osx to know what to look for.
