From what I can tell looking at this: https://github.com/pure-data/pure-data/tree/master/linux

The macOS Pd build uses autotools, so it should be built with JackMP weak link support enabled.

Hey

Sorry for nagging about this again, but I'd like to know whether the
lack of direct Jack support in the macOS build is intentional.
