Darwin, OS X, PureDarwin, macOS (Intel) all default to AT&T
(as does clang on the platform - I am not even sure if Intel syntax is supported for macOS/Darwin there either).
.. we can be 100% sure that any Intel syntax support is (at least almost) completely untested.

NOTE that the GCC gfortran (and Ada) remain the tools of choice on macOS (and they also need the assembler).

It would be pretty difficult to change the default; if GCC changed, I’d only end up patching the Darwin port to default to AT&T .. perhaps a solution for the Windows port is to patch it locally to default to Intel?
