I've got an NEFilterDataProvider that works on Safari and Mail just fine, but when I open Maps, Maps is able to load tiles without any callbacks in NEFilterDataProvider. Even if I have the NEFilterDataProvider just return     return [NEFilterNewFlowVerdict dropVerdict]; Maps is still able to download new tiles, and I see the traffic on the wire. This is on today's current GM macOS (not Big Sur). How do I get callbacks for Maps? And what other Apps are able to bypass NEFilterDataProvider?

Hello, Is IOUserUserClient still the right way to communicate with user space clients if you are building drivers for non network, serial, HID or SCSI devices? Will IOUserUserClient be documented this year? Thank you.
