What are the best macOS apps for developers?

Hello everybody,

I have recently adquired a MacBook Pro mid 2012 which is enough for me as developer. I would like to ask you for some applications usefuls for a developer. And of course apps available only for Mac like the Deco IDE for React Native, or mac and Windows like SourceTree.

Note: I am Linux user, and there are some apps only available in Windows and mac, it is one of the reasons I am asking :)
