I upgraded my macpro recently from OS X 10.6 to 10.8. Now (couple of weeks later) I ran an small update for OS X 10.8, and something not so funny happened.
The updater asked me to reboot my system. Before the reboot, it told me something like:
“None of the updates could be installed. An Exception occurred.”
Since that moment, whenever I try to log in, I end up in the infamous “login loop”: I enter my password, see a gray screen for about 20 seconds, and end up on the login screen again.
OS X version
$ sw_vers ProductName: Mac OS X ProductVersion: 10.8.3 BuildVersion: 12D78
OS X update
The update consisted of four parts, one of them being iTunes (I think iTunes has never worked after I upgraded to OS X 10.8; this was probably an iTunes 10.6 - 10.8 upgrade or something?). The other three I don’t remember.
What I’ve already tried
- I’ve tried to log in as another user. Same problem. So it doesn’t seem to be user-specific.
- There are a lot of posts out there suggesting that it may have something to do with a corrupted launch service cache. There was indeed a file named “com.apple.LaunchServices-034501.csstore” (as suggested by posts below) on my machine. I removed it (in Single-User mode). Didn’t help...
- File system check:
fsck_hfs -r -f -y /dev/disk1s2
The log files are too large to include here. I'll try to paste some (to my own judgement) relevant stuff in the comments below.
The OS X update took place around Mar 24 13:50. At 13:52:32 I see the first “Exit timeout elapsed (20 seconds).” (I think this is the log in timeout).
Some errors in the log file were there before Mar 24 13:50, so I guess they’re harmless (like “The following StartupItems failed to start properly”).
All help highly appreciated because I'm stuck. Also, if you know of a forum that's more suitable for this kind of problem, please let me know!
