Here's the friction almost nobody warns you about: Microsoft Remote Desktop cannot remote into a Mac. Microsoft's Remote Desktop / Windows App connects to Windows machines. It is a Windows-target protocol. There is no “host” mode for macOS. So the very common task — I'm on my Windows PC and I need to get into my Mac — has no built-in answer on either side. (Going the other way has its own snag: RDP into a Windows PC requires a Pro/Enterprise Windows edition on the target; Windows Home can't be an RDP host.)
If you searched remote into mac from windows or remote desktop mac to windows, that's the wall you hit. Scry is built to not have it.
