For what subset of notepad++'s features? I've known a few users, and their patterns range widely. Some hinge on one specific feature, others just want a basic syntax highlighting editor that doesn't fight the system (i.e. Electron, gtk, vim, emacs).

TextAdept worked for the lightweight side, as it also uses the same Scintilla editing core. But way less menu entries and customization features.

CotEditor and BBEdit's basic feature set (that replaces TextWrangler, although you can even still use the same icon) might be appropriate.

But yeah, if you're really into some aspects of notepad++ or depend on special features, it's hard.

Have you tried UltraEdit? I used it 10 years ago, so I don't know how well it has aged, but I preferred it over Notepad++ at the time.

The reason why I don't use it now is because IntelliJ and vscode covers most of my need, and it's hard to justify the extra expense at my work place. I sometimes miss how well UltraEdit worked in multi-column mode and hex edit mode

Maybe you could try to build Notepadqq for MacOS [1] but it's not well integrated at this time.

+1 to this. Moved from Windows ~5 years ago and Notepad++ is one program I still dearly miss.

Have you tried BBEdit?
