I'd hypothesize it's due to https://github.com/versotile-org/verso/blob/07a88a86347c6763... and I thought maybe that was the lowest GH offered since they used an actual number versus "-latest" but no, GH does offer 12 https://docs.github.com/en/actions/using-github-hosted-runne...

Since they already went to the trouble of writing the GHA, I just downgraded and gave it a whirl and it both completed and the resulting artifact launched a-ok on my 12.7.6 x86_64: https://github.com/mdaniel/verso/actions/runs/10341237698/jo...

I'm posting this reply from that build, although I had to compose the answer over in FF because the textarea doesn't scroll :-D

Thanks a lot! It works, but it's pretty unusable, even Google doesn't work and just hangs (like almost all other sites). Only HN seemed to work.

it's five years old release. Sounds reasonable or you're expecting release to work all the way back to commodore 64?

macOS 13 was released in Q4 2022.

My bad, I was thinking 10.13.

Apple makes it relatively difficult to support old versions of their OS. You pretty much have to keep an old computer around and just not update its software. So it might not have been a conscious choice, rather they just didn't go to the extra effort to support older versions.

Their build and testing platform is on Github Actions which supports macOS 12. Furthermore, Apple supports running macOS in a virtual machine or a dual-boot setup.
