How to change password on 2009 MacBook Pro when you forgot your master password
I cannot get into my 2009 MacBook Pro 15”
It is set up to reset the password with a “Master Password” which, of course, I also do not remember.
I have purchased a new M2 MacBook Air and already have an IPad 9th Gen. I know the password currently associated with my Mac ID. I thought the new password would get me into the 2019 but alas, no joy and I am now locked out.
On my IPad I see only my newer apple products: M2, IPad 9, IPad 7. I am guessing this is an OS issue. God knows which OS is on the 2009 MacBook Pro.
I probably have files/images on the old MacBook I want to retrieve. It tells me it has not been backed up in a gazzilion months. How do I get into the old MacBook Pro?
Thanks in advance for your help.
