But it wasn't effective everywhere and I'm not convinced it was intentional. it could be some kind of special thing with permissions, but I was running as root. This was repeatable on all newer G4 hardware I tried it on at the time. It did work on a Dual G4 550, so I also managed to get a backup finally. Also, it was with Panther I first encountered this, so it wasn't in Jaguar I think. It seemed only to be effective in newer machines with Panther and the type of CD-R burner could be affecting things as well. It should be noted that it was only original Apple CDs that were copy- prevented that I had these symptoms with. I managed to make backup copies of my uncopyable (hole in the disc) audio apps on the same machine, which was wonderful as I could store away the originals, instead of using them on the road for authentication and such. Wasn't there also a similar story on Tiger/Toast 7? Prevention of some music burning? To prevent copying is of course not malicious, just an inconvenience. What I didn't like about the prevention was that it didn't inform of what was the problem.
