How can I reset a disabled macbook pro 2010 The password was reset a long time ago, and I have no idea of it. I do not have access to the original owner of the macbook pro. When I turn it on, I have to enter the firmware password, but of course I don't have it. Is there anything I can do to reset the OS, or even install Linux via a USB?
Technically, NO 

If you can't remember your firmware password or passcode, schedule an in-person service appointment with an Apple Store or Apple Authorized Service Provider. Bring your Mac to the appointment, and bring your original receipt or invoice as proof of purchase.
