Options for running Sentinel on an Apple Mac running macOS

Covers options like running Windows natively, using a Virtual Machine (full-featured Windows inside macOS), or simply running Sentinel inside macOS using a lightweight Windows runtime environment.

Options for running on an Apple Silicon Mac

The above only applies to Intel Macs. The newer Apple Silicon Macs can run some Intel software using Rosetta 2, but it can't run an Intel-based OS like Windows. Apple Silicon uses the ARM instruction set, so ARM native software runs nicely there. Microsoft has a version of Windows 11 for ARM under development, and is free to download. Once Windows 11 is run as a virtual machine on Apple Silicon, MacOS allows it to use Rosetta 2 to run Intel applications. Such as Sentinel.
This article gives instructions for three different ways to run ARM Windows on a Apple Silicon Mac. Of the three, UTM is the simplest and least expensive (it's free). I've run Sentinel with it on an M1 MacBook Pro, so I know it works. Just remember you're running a version of Windows that's still under development, so things are a little rough around the edges.
One oddity with UTM (Parallels and VMWare probably have their own quirks) to be aware of: When you plug the scanner into the USB port (you'll probably need a USB-A to USB-C adapter) select Mass Storage Device on the scanner when asked. At this point, the scanner will mount as a disk on the Mac. In order for Windows under UTM to see the USB device, eject the mounted scanner from MacOS. At this point the Windows VM should see the scanner, and you can use it in Sentinel.
