Nobody else has pointed this out, but a MacOS port of Notepad++ actually goes against some of the branding. Notepad++ very much markets itself as a lightweight and speedy thing that uses the low-level Win32 API directly. It is not just a native application, it is a Windows-native application. Porting it to macOS requires a level of care and expertise which is tantamount to changing the entire organization.

I am sure the Notepad++ team is perfectly fine focusing on Windows expertise and has no interest in bringing in the overhead of another OS. If a serious macOS expert wants to do that, they can fork the project with a different name.

BTW look at the GitHub issues. This is a lazy developer creating a slop project. It would be stupid to bring this incompetent and dishonest person on board.
