Re-enable experimental support for cvmfs on macos runners #28
Conversation
While macfuse is no longer an option, there is now a nice alternative with fuse-t. This PR adds experimental support (I've successfully tested it with the nightly build, but there is no released cvmfs version with fuse-t support yet). 'Synthetic firmlinks' are used to create /cvmfs , since the root file system is now read-only on macos. One todo: need to check if we actually need the homebrew action or it can be moved somewhere else.

Cool! Great to see macos support come back :)

How long do these steps take, and can they be cached like we do with apt archives above?

It's 20 seconds for setup-homebrew and 20 seconds for these steps to install fuse-t. Seems like homebrew is not as easy to cache, at least I didn't find a simple recipe. So not sure if possible.

homebrew has this: https://docs.brew.sh/Tips-N'-Tricks
and specifically "Pre-download a file for a formula" section might be interesting for us as it mentions caching, but I need to investigate a little bit

Alternatively, it may also be faster to just directly install the .pkg for fuse-t : https://github.com/macos-fuse-t/fuse-t/?tab=readme-ov-file#other-details

This is indeed faster (10s). I updated the setup accordingly.

Also this might be interesting in the future: https://github.com/macos-fuse-t/fuse-t/wiki#experimental-fuse-t-framework
Maybe it could be possible to get rid of downloading and installing the separate package at some point

This looks good to me. Do you want to make more changes or are you ok with merging this? I assume you have merge privileges here :-)
