Okay, I'm really in bad shape, any help is greatly appreciated. Shortly after running a bunch of software updates (upgrading iTunes, Quicktime, I think there was a point update to OSX) my Macbook started deteriorating, now I can do hardly anything. The first clue was when I tried running an app from the Dock, the icon disappeared from the dock, replaced by a blank space. Then, when I tried running applications from the finder, they would immediately crash. Console had each crash with either "error 1" or "exited with segmentation fault." I ran Disk Utility off my MacOS install DVD; it found and corrected a couple of errors (Keys out of order, incorrect number of files & directories; maybe something else minor.) Repaired permissions. No help. Ran Hardware Test (extended) - no problems seen. Tried to boot in Safe Mode, but after I entered my password, never really loaded the finder (got the background screen, and the menu bar items appeared in the upper right corner, but the menu bar itself wouldn't load.) I booted into single-user mode, ran fsck -fy, "no problems found." So, I have two issues. One is, how do I fix this problem. Two, is there any way I can try and backup my files? The finder won't let me drag/drop files; the install disc doesn't seem to have any mechanism for backing up files. I tried cp -R from my home directory to an attached USB hard drive (when booted into single-user mode) but I just got a scrolling screen of errors. Any ideas? (Help me Obi-wan Kenobi. You're my only hope.
