on macOS, sign the app so that it does not get blocked from opening
found this to sign the app, but the only thing is you have to pay apple $100 a year for a license to sign with, also looks like its a manual process every time there is a new release.

I already did quite a bit of research for this. electron-builder can already automate the whole thing, but the $99 per year is prohibitive for a small open-source project that doesn't make any money.
I guess the help wanted tag is a bit unclear. I'll create a looking for sponsorship tag instead to make it clearer. Unless users are willing to sponsor this or I start making a lot of desktop apps (especially commercial apps), then I don't see doing this any time soon.
Looks like Apple has a fee waiver program, though it is unclear if free open-source projects qualify for this. If I understand it correctly (and I very well might not, because it seems vague on purpose), you need to be a legal organization, which comes with its own barriers to entry.
