How to create new MacBook admin?
My father passed away last year and left me his MacBook Pro, it isn’t password protected so I’m able to use it but the email he used for the admin no longer exists (it was a company email) and he didn’t remember the password either in his final weeks. I want to change the admin to my own email now without having to completely reset the laptop so that I don’t have to lose the photos and files he had. Is there a way to do this at home or will have to go into an Apple store? Basically what I’m trying to do is update iTunes so that I can back-up my iPhone 8 before I pick up my new iPhone 11 tomorrow, but the current OS is Yosemite so I need the admin access to update it to Catalina first to update iTunes.
