Question

how can I reset my "unlock the disk Macintosh HD"?

Trying to get into a MAC Book pro I previously thought I had no access to, due to the grey screen of death. Rebooted it today, got to an enter password to unlock the hard drive screen. I forgot my password, since I changed it in previous rebooting attempts.

Hello brianlandrytenor,

Thanks for using the Apple Support Communities.

I see that you are being prompted to enter a password to unlock the startup disk on your Mac. It's important to make sure that you can start up and log in to use and enjoy your Mac, so I'm happy to help out.

It sounds like you are referring to FileVault, which is a password protected feature that prevents unauthorized access to the information on your startup. You can try to reset your password by following the steps in support article: Use FileVault to encrypt the startup disk on your Mac , specifically:

Reset your password or change your FileVault recovery key

If you forget your account password or it doesn't work, you might be able to reset your password.

If you want to change the recovery key used to encrypt your startup disk, turn off FileVault in Security & Privacy preferences. You can then turn it on again to generate a new key and disable all older keys.

Let me know if you have any questions.
Cheers.
