Match the range to what your host's NAT actually hands out. `doctor` reports `local network
access` as a pass once it can see this. This is the deterministic fix for an unattended host —
see [Local Network: the app is not listed in System Settings](#local-network-the-app-is-not-listed-in-system-settings)
for why the interactive grant is not.
3. Or grant it interactively: run `gitea-macos-runner vm boot --image default` from a Terminal in
the GUI session and click **Allow**. The app is not listed under **System Settings → Privacy &
Security → Local Network** until it has made that first attempt.

## Local Network: the app is not listed in System Settings
**Symptom.** `doctor` prints the `local network access` note telling you to approve the app under
**System Settings → Privacy & Security → Local Network**, but the runner is nowhere in that list —
so there is nothing to switch on.
**Cause.** This is expected, not a bug. The Local Network list is populated lazily: an app appears
there only *after* it has actually attempted a local-network connection and been evaluated. It
cannot be pre-approved. A freshly installed runner that has not yet reached a guest has no entry.
There is also nothing to query, so `doctor` cannot tell you the grant's state. Unlike most macOS
privacy controls, Local Network privacy is not stored in TCC — per
[TN3179](https://developer.apple.com/documentation/technotes/tn3179-understanding-local-network-privacy)
the checks live "deep in the networking stack" as a Network Extension packet filter, so the
permission is absent from `TCC.db` and `tccutil reset` does not apply to it.
**Fix — interactive.** Make the app connect once, from a GUI session where a human can answer:
```sh
gitea-macos-runner vm boot --image default
```
Click **Allow**. The entry now exists and can be toggled later. Do not wait for the LaunchAgent to
trigger it; a background agent cannot answer the prompt, so it simply fails to reach the guest.
**Fix — deterministic, and what to use on a CI box.** Allowlist the VM subnet instead. It is keyed
on the network rather than on the app, so no prompt is involved and nothing needs redoing:
```sh
sudo defaults write com.apple.network.local-network \
AllowedEthernetLocalNetworkAddresses -array "192.168.64.0/24"
sudo defaults write com.apple.network.local-network \
AllowedWiFiLocalNetworkAddresses -array "192.168.64.0/24"
```
Reboot afterwards. `doctor` then reports `local network access` as a **pass**. Both keys are
Apple's, documented in TN3179; the same pair is what [Tart's FAQ](https://tart.run/faq/) recommends
for this exact problem on CI hosts.
> **Why the interactive grant does not stick here.** This project ships an **ad-hoc signed** bundle
> (`codesign --sign -`), and TN3179 notes that "local network privacy uses your main executable UUID
> as part of its implementation". The linker writes a new `LC_UUID` on essentially every rebuild, so
> a rebuilt-and-reinstalled runner can read as a *different* program and prompt again — while the
> old row lingers, since macOS provides no way to reset a Local Network decision to undetermined.
> Expect duplicate entries after a few upgrades. The subnet allowlist avoids all of this.
