If this is a new-to-you Mac, I strongly encourage backup, wipe, and re-install, as otherwise this and other updates will be associated with the previous owner’s Apple ID, and the previous owner may (or will) retain the ability to remotely reset this Mac. If you have forgotten the Admin password, use the Reset Password Assistant described here:Ĭhange or reset the password of a macOS user account - Apple Support

If your user is not listed as Admin, use that Admin user’s password. If your user is listed as Admin, use your login password. iIs your user listed as an Admin, or is there a different login listed as Admin. If the latter, open System Preferences > Users & Groups, and look at the list in the left column. Here’s how to reset password on Mac from Recovery Mode: Access Utilities in the Apple menu Choose Terminal from the Utilities window Type resetpassword (in one word), and click Return Go to the main hard drive and choose your user account Lastly, change Mac password, create a hint to easily recollect it in future, and click Save. This will cause macOS to be i stalled and associated with your Apple ID. Delete the Password Manager app by dragging it to the trash (MacOS) or by selecting Uninstall in the Control Panel (Windows). If the former, follow the steps above to back up your files, and wipe and reinstall your Mac. Option 1: Use another device to re-pair If Password Manager is also being used on another device, you can remove the app from the locked device, reinstall it, and then pair the devices again. So you do not have your Mac’s administrative password? Is that because this was a new-to-you Mac with macOS already installed and configured, or because the password has been forgotten?

I have a new update, MacOS Catalina, that requires an administrator password.
