Didn't know this, but I'd rather not use github to be honest. Isn't there also some kind of signing required to publish a Mac build?

You don’t need to sign it, the user just has to do some leg work to run it without it.

you're right, I wasn't aware of it. Of course you could build it and leave it as is, so we would need to accept the binary, but still - a lot of work. Makes some good projects made by devoted programmers exclusive to other platforms, sadly.
