- xenadu02 6y agoApple apps bypassing NEFilterDataProvider on macOS is a bug.
- wizee 6y agoThe PF (BSD Packet Filter) firewall built into Mac OS covers apple processes. However, I don't think its interfaces are sufficient to implement the functionality of Little Snitch. The new-ish NEFilterDataProvider API used by Little Snitch on Big Sur is neutered by allowing Apple apps to bypass it.
