I am also having issues related to the Sonoma update. I have QuickBooks for Mac 2020. When I would go to the Home Page to create an Invoice then I would get the spinning ball. So I got on here to try and fix it. I saw a link to download QuickBooks Desktop 2021 since it seemed that was still support and I was panicking. So I downloaded it, everything went smooth. No more problems. But I can’t register it. I never got an email with any numbers. I was thinking somehow it was a free upload. When I try to choose Manage license… Buy Additional License is gray and can’t be selected. I can only open it 13 more times. I have Version V20.0.12 R13.3 and it says User Licenses 0.
