For me: Git Tower, MoneyMoney (German banking app, absolutely fantastic), Fantastical, to some degree also OmniFocus.

Plus first-party apps like Safari with its fluid trackpad gestures, Photos with its iCloud integration, and of course Xcode, because being able to build/debug things for macOS/iOS is a bonus feature I can offer as a developer.

The list is a lot shorter than 10 or 15 years ago. Most new apps that come out are Electron, but even then there's sometimes no Linux port (Trello, WhatsApp).
