Thanks for the help. I was just confused about the “missing“ path, then I used otool(1) utility in hope of knowing the actual path but got shocked like “what?! the utility lied to me too?” with no knowing that they are ”cached” at somewhat rather than at filesystem. I’m curious that do they live in memory since boot just like kernel XNU too? Can I inspect that behavior less or more, or they are part of kernel components in some sense? And I noticed the Objectiv-C documentation was update. Great improvemen!
