Apple Silicon Build Support
Sadly, one thing I only discovered after I finished building the release pipeline here is that GitHub Actions currently only supports macOS Catalina, which cannot produce macOS builds containing both Intel and Apple Silicon architecture slices.
GitHub is estimating it's a few months out before they'll be able to roll Big Sur out, so until then, this app might have to be run via Rosetta.
Granted, people are reporting that it's possible to just side-load the real YouTube Music iOS app on Apple Silicon, so maybe this isn't so much of a deal-breaker.
I'll keep an eye on this. If it looks like we absolutely need Apple Silicon support, MacStadium has already reached out and offered to host project on one of their M1 Mac minis. :)
I just try to build the universal app and it's work without any problems.
