Bought a new iMac. So I wiped out my old iMac 27" and put a new system on it months ago. I forgot the password. Holding Command r only brings up a black screen with a pad lock. When I am on my new Mac under system settings Apple account, I can see my new Mac and old Mac. What do I do to be able to reset my old Mac's password? Thanks
iMac 27″, macOS 12.7
The padlock screen indicates you have a firmware passcode set. if you don't remember the firmware passcode, the only way you're ever going to use that machine again is if you can provide Apple with the original proof of purchase for the machine.
If you don't have that, it's officially a boat anchor.
