My mom's MBA is really outdated and with Catalina on the Horizon, my OCD for software updates is tingling. The problem is she forgot her App Store password and the password of the email address she used. Any advice or workaround for this? I bought a 1TB to backup everything and this is the first time I am working on a MacOS. I am not sure if this works like iOS that it gets iCloud locked. It's her workhorse machine and we can only afford a day of downtime. Some things I can think of if it's feasible is to create another admin and migrate there. And delete the old profile? Or backup everything and reinstall the OS. Appreciate the help!
