Arduino IDE 1.8.12 compile Printer firmware on a Mac OS 10.15.4  

RE: Arduino IDE 1.8.12 compile Printer firmware on a Mac OS 10.15.4

I have been going crazy over getting it to compile on OSX Catalina as well. Did you manage to make any progress?

RE: Arduino IDE 1.8.12 compile Printer firmware on a Mac OS 10.15.4

This is the error message I am getting:

Arduino: 1.8.12 (Mac OS X), Board: "PrusaResearch Einsy RAMBo"

I am having the same problem. Any progress?

Stay safe,
