It's not really a hack and it's not the way it actually works (unless you have an extremely badly written graphical app and dismiss every OS API). On top of that, it works great on most hackintoshes as long as you use proper supported graphics hardware. TV's, VR headsets, projectors, monitors, it all works fine. The only problem you have is when you get used to it, almost all other operating systems and non-HiDPI displays are utter crap.
