Lost admin password
I know own several Macs, having made the move from a pc. The first Mac I bought was a Mac Mini Power PC G4, which was soon updated to Tiger.
I have now passed that Mac mini onto my son so that he too can be a convert to Macs but I have a problem.
When I updated and later subsequently re-installed Tiger (to give my son a 'clean' hard drive) I omitted to install iLife 6 which he would like to add but the Mac won't let him install anything without my administrator password which of course I cannot remember. Therefore it appears that the only option left to me, is to do a complete re-install of the whole system and register my son as the administrator.
I have tried the trick of inserting the OS9 install disc, re-starting and holding down the 'c' key when I hear the tone. The 'c' key is then released when the grey screen bearing the Apple logo and spinning 'gear' appears, but the machine just starts as normal and asks for the forgotten password!
I have thought about re-formatting the hard drive using the Disc Utility App but the option is not there to do so on the 'Erase' tab, so does anyone know how to make this machine get back to being 'fresh out of the box' state? (Mac OS9 with iLife 6).
Many thanks, Ken
