Administrator password reset on old macbook pro
I have an old 2012 Macbook that has a disc reader. We are trying to read and copy an old dvd from family event. The macbook can read the disc but we need to the admin password to install software to copy. We can't recall the admin password. When prompted to reset using the apple id, it says the apple id is incorrect. We reset the apple id password and it still says it is incorrect. Is there some reason it does not recognize the current apple id and password? Using same email address for Apple id as we did 13 years ago.
