It sounds like you were really unlucky. The last time I struggled with any of the issues mentioned by you is at least 4 or 5 years in the past.
> But you are ignoring the fact that installing software on Linux is still a mess of resolving all the dependencies and the package manager. Where in OS X, it is just a file move to App.
This is also highly dependent on specific experiences. I haven't had any issues with conflicting dependencies on Arch linux in the past few years. And personally I appreciate a system package manager for all software instead of having to download applications and doing drag and drop for installation
OSX comes with some software such as git and python2 preinstalled. However they do not usually keep that software up to date and there is no way for you to change that, which means that community package managers need to be used to install more up to date software versions in parallel to the system ones
That is how my setup works in the terminal. MPD (music player daemon) runs from the start in the background and I can start ncmpcpp in the terminal to choose a album/playlist and then I can close it again or leave it on a different workspace.
Play Pause etc. just work without the terminal. The biggest advantage in comparison most graphical players for me is that there is no startup time. If I want to play a song I can do so immediately and even without leaving the terminal I am currently working in.
There are different issues with OSX though, that colleagues of mine had, that never occur with Linux. E.g. the chore of somehow managing different software versions such as the outdated default one and a second one installed with homebrew. Almost all my colleagues struggled with setting up python 2 und 3 correctly at some point, whereas this just worked for me on Linux.
Some struggled with font rendering between a 1080p monitor and their Retina displays as well.
