complications resolving forgotten administrator password...
Hi. I have an imac 10.5.8 which been in storage for a year or so. Unfortunately I have forgotten the administrator password. I have spent most of the day in forums but am still unable to resolve the issue. I would like to either use terminal to set up a new administrator account, or preferably to use the startup disc to reset my password.
I am not able to reboot in single user mode. I must have set up firmware protection when i got the imac years ago. (I cant fix this without the administrator password.)
...so I can't open terminal or the start up disc from the login screen.
I have tried opening terminal from the guest account (the only account I can get into) and using these instructions:
https://discussions.apple.com/thread/3506318
but terminal tells me that I do not have permission to do this.
I have tried numerous times to open the reset password application in the Utilities folder in the startup disc from within the guest account, but everytime it quits unexpectedly.
At a loss as to what to do. Would appreciate any help!
Thanks.
iMac, Mac OS X (10.5.8)
