After all my school years working and developing on macs, some professional years on windows, I'm on linux for 5+ years. 6 months ago I bought a new slick ~2015 mac book pro to be able to develop some iphone apps. So coming from the other side (wild world of linux), I was disappointed by the last 3 versions of OS/X, and finally upgraded to Sierra yesterday. Endless little annoyances on the GUI side on OS/X (and Sierra)! Some recent issues are, app store crashing when you click the menu and press Cmd+Q, a lot of confusion on the terminal app between the use of command and ctrl, alt, and other key combinations. A lot of drivers being obsolete and unsupported after jump to Sierra. The update/packaging mechanism being a total failure, where I need to update xcode by downloading 4.5GB of files again and again. Apple software appears so far to me an incomplete toy, filled by annoying delaying animations. Apple fails to develop stable software just for couple of hardware, while having a fanatic user base which can accept any kind of planned obsolescence. Sad.
