Would you mind if I ported this to the mac? Will fork it or whatever and include links to donate to you, would just love to have this on my mac.
Sure, it's unlikely I will work on a Mac port myself, I have no experience on Macs. A fork is fine of course, it's free software after all, just please respect project and shader licenses. There's already been an attempt to make a similar app for Mac, https://dirkwhoffmann.github.io/RetroVisor/
