Yeeaaahhhh, not really. I was a diehard "native" person until recently and I can't believe just how much better developing for web technologies is than writing native Mac.
If you're experienced enough to write a polished Mac app (and that is a non-trivial undertaking) you're experienced enough to write a polished front end in Electron.
Use a lightweight framework (e.g., Vue), be sensible about what you're asking Chromium to draw for you and unless you're doing something really simple -- be ready to write a backend in C++ or equiv.
I'm not saying that is easy, but in terms of complexity it's a wash. The upsides are substantial:
1. Multi-platform with very little additional work
2. Modern web standards + a good IDE are so much fucking better to work with, really
3. Easy to drop into WebGL if you need it
4. Less vendor lock-in
The only place I see it making sense is if you're only working with a single platform -- of course, you have to ask yourself how good of a business decision that is.
