Hello, and thank you for asking your question, with
I am Sr. Mac Tech Support Specialist, Terry, glad to assist you.

Here are some steps you can try to resolve the issue:

I have a process here that may work as an alternative, since you do not have the Mac OS X Install disc in order to gain Administrator access.


To reset your OS X password XXXXX an Mac OS X CD or DVD (for Tiger and Leopard), you will need to enter Terminal and create a New Administrator Account:

Here is what you will need to do:
• Reboot your Mac
• Next hold Apple Command key + S key (Single User mode) down after you hear the Apple chime.

• When you see the text prompt, type in the following
terminal commands to create a brand new Admin account (hitting Return after each line):
mount -uw /
rm /var/db/.AppleSetupDone
shutdown -h now

After rebooting you should have a brand new Administrator account.

** When you login as the to the new administrative account.

I hope this helps.

If you have any other questions regarding this issue, please feel free to reply back to this email, I am alway glad to assist. Thanks!

Thanks for your patience.

I want to be able to bring you a resolution for this issue, however because this iMac is an Intel based processor computer with EFI, unlike the Open Firmware of the PowerPC processors of the legacy Macs.

With Open Firmware in the PowerPC processors, the open firmware password XXXXX be reset simply by shutting down the Mac and  either removing and reseating the RAM in a difference configuration back into the logic board.

With EFI, unfortunately Apple has not publized  any way to reset the EFI password. In fact the only way to get around a forgotten EFI Password, according to Apple is, to take the computer in to an Apple Retail Store or an Apple Authorized reseller.

Thus, without a Mac OS X install disc, aside from not having the EFI password, there is no way to gain Administrator access.

If you have any more questions, regarding your technical issue, please feel free to reply to this post as I am always ready to assist. Thank you!
