To be fair, Apple stopped providing security fixes for Mojave ~4+ years ago, and there have been 7 or 8 new os releases since then…
I don’t think it’s reasonable to expect an open source project to support everything
I agree in principle but Homebrew only supports the latest 3 versions of macOS. Right now Ventura 13 which came out in October 2022 is unsupported.
I think MacPorts still supports PowerPC Macs. I would need to rebuild my G5 to verify it because the hard disk is long dead, but last time I checked, it worked.
I get it - it’s a different beast with very different ideas behind it, but MacPorts is BSD-solid, and that’s a lot.
