Thank you so much! I'll give it a try this week and report back. We ended up dedicating a Windows PC to CMTK in the meantime, and it was much easier to set up (once I figured out I needed WSL 2 installed).

I'll see if I can get it working on the Mac, and at the very least be the guinea pig for this new set of instructions. I'm moving to a new lab soon, but I'll make sure the next user gets all this too!
