Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Do you have the Mac OS X installation discs ?
Follow the steps below to reset the password ***** the Admin account.
Restart your Mac and immediately hold down Command and S on keyboard at the same time for 10 seconds. This will boot the Mac into Single User Mode (black screen with white letters)
Type this command and press return --> mount -uw /
Type this command and press return --> sh /etc/rc
Then type this command and press return --> passwd username
Replace “username” with the short name of the user account for which you’d like to reset the password. Then type your desired password ***** press return. You will not see the password ***** enter on the screen, so make sure you write it correctly.
Type reboot and press Enter. Please let me know if that didn't work, so we can continue troubleshooting.
If you have the Mac OS X installation discs, please let me know as you can also reset the password ***** it.
