I tried applying this theme to my iBook G4 (Mac OS X 10.4.11 Tiger). http://atari.vg-network.com/tigertheme/ I forgot to change the directory to the folder, and ran the script. I noticed that all the icons were not found, so i terminated the process. My terminal stopped working, so I rebooted. It booted up to a shell, then infinitely stays at the blue background of the logon. I tried starting in Single User Mode, and running uninstall. The script hung, so I also terminated it. I haven’t tried install.sh and then uninstall.sh through SUM yet. Any suggestions on what I can do if that doesn’t work?
Alright, it got fixed. I just reran install.sh the way it was supposed to be, and everything worked again.
