It works pretty well on my MBP, and is incredibly handy when you’re trying to track down a leak or a memory-related crash. To get the logs for retain, release, etc., though, you have to make sure to get info on the ObjectAlloc instance and check the “Record Reference Counts” box. Otherwise, you just get allocations and deallocations.
