Author did not mention trackpad at all. I have my doubts the trackpad works well, or nearly as well as macOS. Without it being mentioned, I just shaked my head and went on.

The pre-touchbar macbook pros were still ok. Past that is another story.

I wouldn't even try on a touchbar unit.

I remember horror stories on HN that the newer touchpads are completely unusuable under Linux.

For both hardware and software reasons.

Apple hardware is not generic hardware you can buy off the shelves. Expecting driver problems is not odd because of that.

When I worked for Canonical, one of my teammates had one - a 15" Retina MBP. He tried, for months, get Linux installed on it. In the end, he used a VM.
