MacOS. Project scripts and software are hardcoded for Mac. The alternative is Windows, but making the project dev environment cross-platform takes time. I dislike non-standard keyboard shortcuts for everything, lack of FAR Manager (using Midnight Commander has the same problem as all the different keyboard shortcuts), its constant annoying notification popups that covert part of my windows, its problem with handling non-Apple mice (have to jump through many hoops to make mouse movements sensible, put mouse wheel in the proper direction etc), its windows rounded corners that cut at the application's view area (run Alacritty without status bar, the rounded corners at the left bottom corner will obscure part of the shell prompt), its support for Linux that is significantly worse than in Windows and probably more that I cba to remember.

The other thing that I dislike but can't get rid of is JVM. Mind you, Python, Go, Javascript and so on is worse, but JVM is what I have to work with, unlike the rest of them.
