The biggest issue for me though was Darwin's weird psuedo-complete unix environment. All of my production servers are Linux, and it's a real pain to have to torture software that works great on Linux over to Apple's OS. Homebrew is nice, but even that would fail sometimes, and if the software wasn't available I would have to wait for someone smarter than me to port it. Also, it's weird that the community has to maintain this despite Apple having a gajillion dollars because they simply do not care about OSS.
More of a personal ancedote, but in the end all I'm really using a computer for is a web browser, code editing, and running linux production software locally. Just made more sense to stay on Linux, which I run on an excellent Framework laptop. It feels nice to be out of the software bloat treadmill.
