I got an old Mac G4 (powerPC) from the company who wanted to put it in a bin. The company agreed that I can take it home for private use.It is running an early version of OSX but because it is old and the person in charge no more in the company, I do not have any login/password for entering the system.Is there any procedure to either create a new user or to reset the password of an existing user?

You can boot any OS X based Mac into single user mode by holding -S as it boots. You need to have it pressed by the time it gets to the gray boot screen. Once the gray screen disappears, so that you can see the text mode boot stuff, you can let go.Once you get to a prompt, you can reset the primary user's password. Reboot, and you can then log in as that user.Alternately, download an OS disc ISO appropriate to the machine's age, and reinstall the machine.
