Speaking of infuriating trackpad issues on macOS: Have you solved the three button problem on Linux/BSD over VNC on MacOS? I had it working on Ubuntu 14 & 16 and FreeBSD 11.3, but now it is busted on 18 and 20. So annoying.
TBH, I'd really like to work for the FCC doing this stuff. I know it's grunt work, but it would be such a great end-of-career job to scrutinize hardware to the nth degree, and just have to worry about doing a precise job, not a fast one.
