I believe it's possible, I'll get Mooon to reply to you about it! :D
Hello, it's already possible to do it :D and there is a link to all supported processors and OS' but short answer for Mac is:
Apple Silicon processor: npx electron-packager "./" "BubbleWrap" --platform=darwin --arch="arm64"
Intel processor: just replace the "arm64" for arch with "x86_64".
Oh OK! I'll do that
It will be possible in the future to create installers for the desktop variants and (specifically for Mac) sign with your apple developer id. I'm currently working on this.
Thank you! If I'm not mistaken, signing with a developer account is important for Mac otherwise most people won't be able to open it
