Given all the friction and various issues, I still don't see why a hackintosh with well-supported hardware running macOS isn't an option.
I actually wrote about my experience: https://medium.com/@Ezhik/2fb487efe717 - but even disregarding obvious concerns like legality, there's still plenty of reasons to want to give Linux a shot properly, which mostly come down to the direction Apple is taking OS X and its hardware in.
On top of that, I've actually had to spend far less time computer janitoring it than I have on the various *NIX installs I've run in those same 6 years.
I totally understand not wanting any OS-based surprises while trying to get work done, but as long as your CPU and motherboard are supported, you're generally good to go.
