Looked at that. No luck.
I'd actually had my laptop (macbook air) into the apple genius bar TWICE this past month with this as one of several issues (the main one being not being able to recover disc space after deleting programs... for some reason OSX Lion was holding the space in the delete folder and not releasing it - not until the genius bar guy did a command-R startup and repaired permissions and did some cut-paste work with my home folder. I had to back everything up on a peripheral HD and bring it into the shop, took hours).
"Genius" tried fixing the password/permission thing twice, went through all the regular settings, said the other three guys in the backroom told him all we needed to do was the command-R/repair permissions thing and it would work. It didn't. They were stumped.
THESE WERE APPLE-TRAINED TECHNICIANS. With all their resources available.
It wasn't until I got home, did a search for this problem and found the solution on this forum.
This is too much like using a ****** windows PC for me.
All this time I thought macs "just work."
A rare series of unfortunate events, software glitches, update issues, who knows. System seems to be working now, except I installed Windoes 7 under VMware over the weekend and ran into the same problems. Temporary files being saved, delected files saved, etc.
Started with 150 gB on HD, after installing Win7 I only had 70. Really? Win 7 is a 70 gB program? From a 4 gB disc (or is that a 750 mB CD? Plus 130 some update files?). I ran disc inventory X, found the trash was full, deleted everything, rebooted, and I've still got 127 gB free. Better than it was, but again, this is way too much like a PC OS to me and I don't need another hobby.
I upgraded to Mavericks, let's see if any of this goes away or it's back to the "genius" bar for another round.
