So the funny thing is how well macOS works even when it doesn't have the right drivers. At one point I tried and failed to set up a Hackintosh on unsupported hardware, but I was shocked to find how good it looked even with the default VESA video driver!

While Linux's VESA driver got tons of screen tearing issues and generally poor drawing speeds, Mac OS (this was 10.4) was sitting there drawing a fully composited desktop with no slowdowns whatsoever. At that same time, Linux required special graphics hardware with beta drivers to even get any form of desktop compositing working.
