neither macOS nor Linux feels much like "Unix" when you do non-1970s stuff (graphics, webcam, low-overhead profiling, introspection, some networking, IPC and weird MMU stuff, low-overhead polling/IO/subscriptions)
but Linux at least tries with /proc and /dev/videoX and new file descriptors like userfaultfd and pidfd and so on (and fork(2) still kinda works). macOS really makes no attempt to be Unix-like in comparison https://social.omar.website/@omar/statuses/01HWGZM1ACNS48HEQMFBCW0VAY
