<!--Delete sections as needed --> ## Description Adds a Mac troubleshooting topic for containers that can reach the internet but not devices on the local network (LAN). The cause is Docker Desktop not having the macOS **Local Network** permission: macOS then blocks container traffic to devices on the local network, including the router, while internet traffic still works. The fix is turning on Docker in **System Settings** > **Privacy & Security** > **Local Network**, which takes effect immediately, without restarting Docker Desktop. Also adds a short **Local Network permission** section to the Mac permission requirements page that links to the new topic, since that page didn't mention it. **Verified** on macOS 26.7 / Docker Desktop 4.92.0 by toggling Local Network for Docker: - Off: containers couldn't reach LAN peers or the default gateway (ping, TCP, UDP DNS), while the internet and `docker pull` kept working. - On: access came back immediately, on the same backend process, without restarting Docker Desktop. - **On a fresh install, macOS prompts for the Local Network permission, so users who hit this have most likely denied that prompt at some point.** ## Related issues or tickets - https://github.com/docker/desktop-feedback/issues/636 ## Reviews - [ ] Technical review @mat007 - [ ] Editorial review - [ ] Product review --------- Co-authored-by: Allie Sadler <102604716+aevesdocker@users.noreply.github.com>
