How can I remove a macbook password? There is a password for administrator too.?

Answer 1

If you don't have at least the Admin password, you're beat. OS X, and all other Linux versions, are built to prevent access without passwords.

Assuming you have OS X, do a clean install and start over. I hope you backed up all your data.

Answer 2

Don't listen to the other guy you are not beat you just need an OSX install cdrom that came with your Computer.

If you are using Mac OS X 10.3.9 and earlier, use this method
to reset your admin password.

You will have to have the Mac OS X install CD which should have come with your Mac. Following these steps shouldn't affect your keychain or any of your other passwords.

Turn off your computer and insert the install CD.

Press the 'C' key while you turn on the Mac and hold it down until the Apple logo appears.

Select 'Reset Password' from the Installer menu and choose your username. (Don't choose 'System Administrator' as a name.) Then follow the prompts.

If you are using Mac OS X 10.4.x "Tiger" and later, use this method:

You will have to have the Mac OS X install CD which should have come with your Mac. Following these steps shouldn't affect your keychain or any of your other passwords.

Turn off your computer and insert the install CD.
Press the 'C' key while you turn on the Mac and hold it down until the Apple logo appears.

Select 'Reset Password' from the Utilities menu and choose your username. (Don't choose 'System Administrator' as a name.)

Then follow the prompts. (In other words, for Tiger, Apple moved several features to a "Utilities" menu, rather than the "Installer" menu.)

Hope this helps.
