Generally I am pretty happy with macOS and I still believe it to be the best option for a desktop. Where I'm getting frustrated is the increase locked down nature of the OS. I get that it's for security, and that's fine for my dad, but it's starting to get in the way of me down my work.

So when you already start feeling like the operation system is preventing you from doing the things you need to do, then all the small cosmetic flaws seems more in your face.
