Yeah, but ASan requires recompilation. GuardMalloc and MallocScribble apply to your whole process, and so even malloc()s called by system frameworks (ex AppKit) get checked. I've found several OS bugs this way over the years. Maybe internally Apple has ASan builds of the whole OS, but they don't distribute it externally.

Security-critical components like the kernel and WebKit have ASan variants, that’s for sure. But they also use custom allocators.
