Welcome to the Community, @DanLA.

Here is information on the operating system, hardware, software, and other needs to run QuickBooks Desktop Point of Sale 19.0 so you can have the best experience possible.

Every version of QuickBooks has its corresponding system requirements. QuickBooks Desktop requires Internet Explorer 11 as your browser. Since it's updated software, it should work with an updated browser to run QuickBooks seamlessly.

For the operating system, here are the compatible windows:

• Windows 10, all editions including 64-bit, natively installed.
• Windows 8.1 (Update 1) all editions with 64-bit natively installed.
• Windows Server 2016.
• Windows Server 2012 R2.

To compare the requirements with your device system information, you can check it before updating QuickBooks Desktop to the latest release.

Additionally, here's an article to guide you in managing your business using QBDT for Mac: User Guide. It contains topics about banking, lists, and getting paid to name a few.

Keep me posted for additional questions or other concerns about QuickBooks Desktop. I'd be more than happy to help.
