Welcome back to RAK forum @tallackn ,
I tried it with my kid’s macOS and seems to got the same issue on the new Arduino IDE 2.x.x.
If possible, perhaps you can try on the legacy Arduino IDE 1.8.x. And if ever you will go on that path, you might encounter python related error. I am sharing to you the fix in advance - [Solved] Arduino "ModuleNotFoundError" in macOS
Seems many of our guides will be obsolete with the introduction of Arduino IDE 2.x.x since these are based on Legacy Arduino IDE.
