Is it possible to block Apple Intelligence from sending data over the Internet via Little Snitch? I would assume it is, but I'm not sure if anything significant has changed in macOS 27 that makes this impossible now. I don't really mind the local features - I'd rather they stay disabled, but it's not the end of the world - but I really don't want any data leaving my Mac.

Is it possible to block Apple Intelligence from sending data over the Internet via Little Snitch?

Short answer: Maybe, but I've never tried it.

Little Snitch is aware of various system-level network connections, but I don't know if they're granular enough to block the AI only.

Apple OS will bypass any user space firewall.

You can verify this yourself. Get an old laptop to act as a wifi hotspot and forward traffic over usb ethernet adapter to your actual router. Then run tcpdump on the computer. You will see the multitude of phone-home traffic.

  • Is there evidence of this anywhere on the internet? I couldn't find anything with ten minutes of searching, and I don't use little snitch, and I'm not going to put the effort in to remediate this just to figure out if this comment has weight.

  • Well, I block all connections to iCloud for every app (user and system) completely with Little Snitch, and the fact that it does indeed break some little features I can absolutely live without, indicates that it has at least some effect.

    But still, I fully share the sentiment that creators of an OS are perfectly capable of bypassing whatever there is running on top of it.
