Are you able to build a macOS version? You can upload to an external site (google drive, media fire, etc) and just share the link here so we can plat and rate it during the rating period.

Well, you can't change the uploaded file during the rating period. Adding the macOS icon doesn't really change anything. If you're able to build a standalone macOS build from the build settings window in Unity (not sure if that's the engine you used) you can then compress the folder with .zip or .rar or whatever compression and then upload that to either your main game page on itch or somewhere else that is not the jam page. And then just throw a link to that here. No worries if can't.
