I have one early 2015 MacBook Pro currently running Catalina 10.15. That’s my production machine;
I got a new 2019 MacBook Air which I want to make my main production machine; The Macbook Air is from summer 2019 and came brand new with Mojave installed;
Is there a way for me to migrate from Catalina to Mojave, using either the Migration Assistant or a TimeMachine backup? If I a restore from a TimeMachine backup, won’t it also restore the Catalina version of macOS on the new MacBook Air?
