You should be able to simply run the executable inside gltfpack-macos.zip. Due to Apple's restriction on running downloaded executables you will probably need to launch it first using Ctrl+Click, see https://support.apple.com/guide/mac-help/open-a-mac-app-from-an-unidentified-developer-mh40616/mac

Thanks for the answer, but in fact when I use Ctrl+Click to open the gltfpack file, I get this error, the file may have been stored with a different text encoding, or it may not be a text file.

Ah, you might be running into a problem where the binary doesn't have the executable flag. You can fix it from command-line like this (specify the actual path to gltfpack file):

chmod a+x ~/Downloads/gltfpack

I'll need to see if the file in the .zip archive can automatically get the right permission when using GitHub Actions.

If this is easier here's a one-liner that downloads, extracts and fixes file permissions for gltfpack; you'd still need to Ctrl+Click the executable once I believe, but after that you can simply launch it via command line.

curl -L https://github.com/zeux/meshoptimizer/releases/latest/download/gltfpack-macos.zip >gltfpack.zip && unzip -o gltfpack.zip && chmod a+x gltfpack

Thank you very much. It is useful to use the above code.
