  The only way to compile a .ev3 file to a .rbf file is with the "EV3 Lab" software that is not compatible with macOS 10.15 Catalina.
  
  So your options are:
  
  1. Run Windows or an older version of macOS in a virtual machine, such as [VirtualBox](https://www.virtualbox.org/)
  2. Find someone that can send you the compiled .rbf file, then use a tool such as [ev3duder](https://github.com/c4ev3/ev3duder) to transfer the program to the EV3.
  3. Write a new program in the new scratch-based programming software.
