I was thinking about patching it via wrapping in __builtin_available check (which I believe is the right one to use, as it should match the -mmacosx-version-min ) - but can't actually think of a quick fix, due to interceptors being defined via C macros.

Sorry for the breakage @wrotki !

Can you share the exact error message that is the problem? I was hopeful that the __builtin_available I used in the unit test was enough to cover us.

After I have a look at that, happy to revert if there is no clear solution.
