Hi @hsinfan1996. As a workaround, I increased the tolerance in #869 (see this commit: https://github.com/LSSTDESC/CCL/pull/869/commits/2b323eafe83dd989aafd067aac3bd788980c4889). With it both ubuntu and mac tests passed.

Thanks. Yes, I think for now increasing the tolerance is the only way.

Just so we're clear, what is the issue exactly? Is it that mac uses a different gsl or something like that compared to python on GHA?

[hsinfan1996]

I still don't know caused the tests on macOS to fail. Amongst the packages common to the two platforms, the differences I can spot are the compilers and libgfortran-related packages. macOS uses libgfortran-devel_osx-64=12.2.0 while Ubuntu uses libgfortran5=13.2.0.

Oh well... I'd be happy to just raise the tolerance and add a comment documented that this is because of mac on GHA (in case we can bring it back down in the future)
