That wasn't true in 1987 and isn't true today.
And Mac is not an acronym.
I assumed I can’t find comparable sofware in Mac land because it was still locked. So there must be some other reason they don’t have the software library that PC’s have. Possibly they came late to the game of open development. I don’t know - I won’t buy a Mac if I can’t run the software I need to run. I’ve used them - they are fun.
