QuickBooks Mac 2019 compatibility with the new Monterey MacOS operating system

Hi there, jbean744.

Thank you for visiting again the QuickBooks Community. I'll be sharing some details on the system requirements and how QuickBooks Desktop 2019 works.

There are system elements that need to follow before you install QuickBooks Desktop for Mac. That said, QBDT 2019 is compatible with At least Mac OS X v10.12 (Sierra); Supported by Mac OS X v10.14 (Mojave), 10.13 (High Sierra). Then, a new Monterey MacOS isn't fit for now.

Once the requirements are good and enough, you can now start installing the QBDT 2019 version. Please open this article to see a step-by-step guide and some things you need to know before you begin: Install and set up QuickBooks Desktop for Mac.

Please let me know if you have further questions about running QBDT 2019. I'm always happy to step in and lend a hand. Have a great day.
