Hi there, @dawnpizzo.

I'd like to inform you with the version of your MAC OS v14.2.1 is compatible with QuickBooks MAC v18.0.14R15.

You may refer to this article to for more guidance: System requirements for QuickBooks Mac Plus 2022.

Additionally, I'd like to leave this article for system requirements for QuickBooks Online products.

As I know you can run QB Desktop 2019 on Sonoma. But keep in mind, every time Apple release a patch to Sonoma, you may find a new "bug" in your QB. When it happens, consider upgrading your QB to a newer version.
