I have downloaded the QBDT 2021 for Mac installer. I am currently using QBDT 2019 for Mac.

1. If I run the 2021 installer, will it let me pay for an upgrade to 2021 and continue to use my Desktop QB?

2. Will QBDT 2021 run under Sonoma?

Thank you for your help, and PLEASE bring back the desktop version. I would happily pay for a reasonable annual upgrade. I just do not want all of my accounting data on the cloud.
