I tried it, but it crashes when you load the WebView. Other devs are having the same problem:

The thread went quiet on April 9. Is far as I can tell, there isn't a working version of Compose for Desktop JSEF or KSET that runs on MacOS. It's hard to build, and when you find the right combination of gradle version, gradle runtime (different version for gradle and compile / deploy), libs, etc, it crashed when it tries to load anything in WebView.
