Resetting Forgotten OS X 10.5 User Password
I have an older G4 Mac Mini I use for testing the Mac app I’m working on (Here, File File F.K.A. Welcome to Your Mac. It’s just nice to have a machine that I can test both 10.4 and 10.5 as well as PowerPC compatibility.

-
Restart into single user mode (hold Command+S during boot). (Note: that if you use a non-Apple keyboard that’s WindowsKey+S)
-

-
Now run:
-
Note your short username and user directory by running:
-

-
Now reset your password by running:
-
Now reboot by running:
This is a bit more complicated than it seems to have been in 10.4 Tiger. I’m fairly certain you could skip steps 2 – 5, since it didn’t use the same directory service backend.
Note: I don’t use secure file vault, but others on the web have noted that resetting your password in this way will lock you out of your data. In fact, it looks like there is not a way to recover/reset that password, which is part of what makes it secure. 🙂
Thanks Google and Apple!
