I wrote a program and I run it on my Windows 8/10 machines at home. I have a friend that has an Apple Macbook and wants to use the program as well. Is there a way that I can port the code on my machine, so it can run on a Macbook? Or do I have to have them install the macOS version on their Macbook, and compile/run my source code? In my younger days with assembly language, we used to call them cross-compilers..... Thanks, Mike
