caching is not working on macos?

I saw the cache being created in https://gitlab.idiap.ch/bob/bob.ip.dlib/-/jobs/157412 but I can't see it being extracted in https://gitlab.idiap.ch/bob/bob.ip.dlib/-/jobs/157414

I can see the cache working in linux: https://gitlab.idiap.ch/bob/bob.ip.dlib/-/jobs/157413

Am I missing something?
