I've got a MBP that seems to be working fine with the exception of the keyboard after a liquid spill. I can connect a USB keyboard and login to the user account and use the computer normally. Replacing the built in keyboard is more of a hassle than I want to mess with so I intend to wipe the HD and then sell it for parts on eBay. I'm trying to enter recovery mode to erase the HD and then reinstall the OS. I'm presented with a "lock screen" after pressing CMD R during reboot. I'm assuming it wants the account password but its not accepting the password. File Vault is turned off. iCloud is logged out. Nothing is typed into the field and absolutely nothing happens. Any thoughts on what I can do to erase the drive and reinstall the OS? --- Post Merged, Jul 25, 2016 --- It appears that this is a firmware password screen. I don't recall putting a firmware password on this laptop but if I did, I know exactly what the password it. It does not accept that password. Nothing (not even asterisks) show up when typing with the USB keyboard. The utility screen does not come up so that I can go in and remove the password if in fact there is one. I CAN login to the user account. Is there anything I can do from there? Maybe in Terminal?
