After running the OS Whose Name I Shall Not Mention on my G4 minitower for several days, I’m now about to take the plunge and install it on my PowerBook. I’ve done a complete mirror backup of the PowerBooks internal drive to a bootable external FireWire drive, which I can use to recover in case of disaster. If I’m not back here in a few hours to report success, most likely something terrible happened.
Update: It works! Nothing terrible happened. I found a few minor incompatibilities, however.
