Meld is one of the first things I make sure I have on a new Linux install. Usually good apps come out for Mac only and the likes of me go all "wot, no Linux version?" but today I learned that until today, Mac users might have said that on Meld.
The same thing for KDE connect two days ago. I am not sure I totally agree with the feeling though, in fact, it's the opposite. Many apps I use on a daily basis are not available for Mac.
