While I'm aware that Windows, Android and Linux is mainly supported, I have been getting igor-setup and igor-build to build for the 3 desktops. However I should note that for MacOSX, it tries to pass off Package instead of PackageZip, which actually doesn't do anything. I've made a fork and been testing it in my spare time, it works fine. Provided that the app itself isn't codesigned (working on that.)

Happy to PR a change later!
