Hello there, @jbean744.

I can share information about the system requirements when installing QuickBooks Desktop for Mac.

As of now the operating system that's compatible with QBDT MAC installation is at least Mac OS X v10.12 (Sierra); Supported by Mac OS X v10.14 (Mojave), 10.13 (High Sierra).

We'll give information and updates once it's supported. I recommend you visit QuickBooks Blogspot to check.

Feel free to comment on the thread if you have other concerns with QuickBooks and system requirements. We are more than happy to help. Stay safe.
