If you lost or forgot your firmware password

Learn what to do if you don't remember the firmware password you set on your Mac, or if you're asked for a password when you try to select a startup volume.

You can use a firmware password as a security measure to make sure your Mac can only start up from your startup disk.

Only Apple Retail Stores or Apple Authorized Service Providers can unlock computers protected by a firmware password if you can't remember the firmware password you set.

If you forget your firmware password, schedule a service appointment with an Apple Retail Store or Apple Authorized Service Provider. If you plan to visit an Apple Retail Store, make a reservation (available only in some countries and regions). Bring your proof of purchase (original receipt or invoice) with you.
