Create mac build on Linux, sign-only on macOS

It would be cool if electron-builder supported Mac builds on Linux. Now, I know that you cannon properly build and sign a Mac build on anything different than a Mac. However, it should be possible to create a build on Linux and sign it later (e.g. via ssh) on a Mac.

What do you think? Would you be open to such a feature?

You can create dmg only on macOS.

How about the .app only?

[develar]

No one forbid you to build tar.gz, tar.xz, dir and other common targets for mac ;) --mac dir or --mac zip. Or set target option (mac.target).

Do you mean that you want ability "point to prepacked .app dir to just sign it"?

[jakubzitny]

Sorry I didn't realize the "dir" option can work on linux, just tried it and it works.

So yeah, now the "sign a prepacked .app dir" option would be quite useful.
