Hi Joe3zz,
It's great to see you in the Community!
Yes, QuickBooks Mac 2020 is now compatible with the Monterey Mac OS version. We've released a patch update (R13) for this in October 2021. If you haven't downloaded it yet, you can follow the steps below:
- From the QuickBooks▼ dropdown, select Check for QuickBooks Updates.
- If a newer version is available, select Install Update.
- When prompted, select Install and Relaunch.
For other update options, please refer to this article: Update QuickBooks for Mac to the latest release.
