I believe there’s no other allocator besides jemalloc that can seamlessly override macOS malloc/free like people do with LD_PRELOAD on Linux (at least as of ~2020). jemalloc has a very nice zone-based way of making itself the default, and manages to accommodate Apple’s odd requirements for an allocator that have tripped other third-party allocators up when trying to override malloc/free.
