A couple of days ago, my 15 PowerBook running Mac OS X 10.3.3 (Panther) was working fine. Now its not. The only unusual things I remember doing were trying to install Firefox (it hung the first couple of times I tried to run it, so I deleted it) and quitting during a reinstall of Bluefish using FinkCommander. Here are the problems Im having, in the order that I noticed them: When I try to run iMovie 3.0.3, it crashes during startup. ~/Library/Logs/CrashReporter/iMovie.crash.log reports: Exception: EXC_BAD_ACCESS Codes: KERN_INVALID_ADDRESS system.log says, iMovie could not be launched prebound. I tried to run iMovie from Terminal and got a Segmentation fault error. I issued a sudo update_prebinding -root / -force command, but iMovie still crashes on startup. I also renamed ~/Library/Preferences/com.apple.iMovie3.plist, and that didnt fix the problem either. When I start Terminal, I get an error message that says, manpath: unable to make sense of the file /etc/manpath.config. /etc/manpath.config contains a bunch of binary junk. When I try to open a message that has an attachment in Mail, I get the Spinning Beach Ball of Doom. Mails CPU usage soars to the mid-90s, it hangs, my laptop gets really hot and eventually the whole machine locks up. Im unable to kill the Mail process using Force Quit or the command line. I end up having to pull the plug and take out the battery to get it to shut down. This happens for any kind of file attachment. Im able to open messages that dont have attachments without a problem. I ran Repair Disk Permissions using Disk Utility. That didnt fix any of the above problems. I ran the Apple Hardware Test on the Panther installation DVD. Everything passed. Now Safari has started locking up. Right after I open it, I get the spinning beach ball. Im unable to force Safaris process to quit. At this point, Im afraid to even turn the machine on. Does anyone have any suggestions? I bought it in December 2003. Its my first Mac.
