My post was more “moving from Apple to Linux” including hardware. but since you’ve asked :)

Of course, I could get Ubuntu running on a MacBook Pro 13 Retina 2013, but it was far from perfect. The fonts were extremely small, the trackpad was quite “off” (to say the least), the Wifi didn’t work as expected (it lost connection every now and then), graphic card wasn’t properly supported, etc. If I want to run a more “exotic” distro, I was out of luck.

Given that one can more or less buy a “cheaper” PC laptop and simply install any flavor and it “more or less” works, it’s just not worth the time (for me).

Just my two cents :)
