Mac is the machine I know least. I have no "full" Linux machine. No experience of Cygwin and its ilk - just a minefield to me.
The best way would be a virtual machine using Virtualbox (https://www.virtualbox.org) (free) or VMWare Player (https://www.vmware.com/de/products/workstation-player.html) (free for non-commercial use).
Install it, then download Ubuntu 20.04 Desktop (https://releases.ubuntu.com/20.04/), and you have everything you need. You can also reroute USB devices into your virtual machines, so using a JTAG/SWD debugger will work.
Caveat: Check your BIOS setting for something like "VT Virtualization support" and enable it. The virtualizers need the CPU hardware virtualization support to be enabled.
