To be fair, if something is on Mac, it is usually on Linux. Windows is a bit different.
That's true only for CLI apps. My most frequently used GUI apps on Mac:
- MailMate
- Affinity Photo
- ACDSee Photo Studio
- NetNewsWire
- ApolloOne
- Textual
- Transmit
- iA Writer
None of them are available on Linux. Most of them are Mac-only (i.e. no Windows version either).
