Apple is the worst about this. "It works on my computer" but it won't on your computer, because Apple will quarantine my code when it gets copied to your computer, so it can't run on your computer because it's "damaged". Unless I pay Apple $100/yr. Microsoft is worse these days, but that's no excuse.
