Hi Rick,

There has never been a correlation between Apple and llvm.org versions of clang.  Apple clang’s start with a branch of mainline, but have *many* changes cherry picked from later revisions.

The best approach is to use __has_feature.  To answer your specific question, Apple clang doesn’t support OpenMP.
