Notes

• Of course, I can't test the itch.io executable signing, so commented that out in my testing.
• The build results in this:

❯ uname -a
Darwin me.local 23.6.0 Darwin Kernel Version 23.6.0: Fri Nov 15 15:13:15 PST 2024; root:xnu-10063.141.1.702.7~1/RELEASE_ARM64_T6000 arm64

❯ file ./artifacts/darwin-arm64/butler
./artifacts/darwin-arm64/butler: Mach-O 64-bit executable arm64

❯ ./artifacts/darwin-arm64/butler -V

I can't seem to compile it myself, mind uploading a copy of the build? I'd like to waste less battery when using itch if I can get away with it

Why isn't there any progress here? Would like to play on an Apple Silicon Mac myself, without Rosetta. If you need any help, let me know!

Sorry for the delay, we're starting to work on pushing out arm builds. There's native shared libraries that ship with butler so it's not as trivial as just adding arm to the list of platforms in the release script.

You can now build full butler across arm linux and macos from the repo.

We now have published arm linux builds on from master branch on itchio, mac os will be coming next https://broth.itch.zone/butler

What about Windows ARM ?

Sure. The 7zip windows arm installer is provided in a different format so I didn't get a chance to add it to the build process yet but I plan to add it.
