i'm making a personal promise to myself right now: i'm never typing an apple id email address or apple id password on a mac ever again.
you have to do it on iOS, because without identifying yourself to apple you can't even install free apps on your tablet or phone. i have throwaway, disposable email address apple IDs for that purpose there, which of course serve as permanent unique tracking identifiers. i'm not doing it on the mac, ever.
@paoloredaelli everyone is still waiting for their librem. until i can buy it with next-day shipping in quantities up to 1000, i file it as vaporware.
