Clear the VPN, DNS and private address settings that hide the sign-in page." --- # Le MacBook ne va pas en ligne sur le Wi-Fi de l’avion, le téléphone oui Plane Wi-Fi holds all traffic until you sign in on the airline's page. The phone often works because nothing on it hides that page. Applies to: All current macOS versions. The Off, Fixed and Rotating options for the private Wi-Fi address are in macOS 15 Sequoia and later. · Vérifié le 29 octobre 2026 ## Symptômes - The Mac joins the plane's network, but no sign-in page opens. - Safari shows a security warning or a blank page. The phone signed in with no problems. - The Mac was online, then the airline's page asks you to sign in or pay again. - The airline's page says that your pass is in use on another device. ## Causes probables - **A VPN or iCloud Private Relay.** A VPN or Private Relay can stop the plane network from sending you to its sign-in page. - **Custom or encrypted DNS.** A custom DNS server or a DNS profile does not use the plane's DNS. The network then cannot redirect you to its sign-in page. - **A new private Wi-Fi address.** The plane network can link a pass to the Wi-Fi address of a device. A new private address makes the Mac look like a new device. - **The phone signed in another way.** The phone can have signed in through the airline's app, or before the Mac joined. It often has no VPN or DNS profile either. - **The airline's own setup.** Airlines and their Wi-Fi providers use different sign-in pages and rules. Some show the page only after take-off. Some ask you to use their app. ## Comment vérifier 1. Hold the Option key and click the Wi-Fi icon. Make sure that you are on the airline's network. 2. Affichez les serveurs DNS du service Wi-Fi. Un serveur personnalisé apparaît ici. ``` networksetup -getdnsservers Wi-Fi ``` Output `There aren't any DNS Servers set on Wi-Fi.` means that the Mac uses the plane's DNS. 3. Cherchez un VPN en haut de l’ordre des services. ``` networksetup -listnetworkserviceorder ``` 4. Cherchez des profils DNS. Sur macOS 15 et ultérieur, choisissez menu Pomme > Réglages Système > Général > Gestion des appareils. 5. Sur macOS 13 et 14, choisissez menu Pomme > Réglages Système > Confidentialité et sécurité > Profils. 6. Choose Apple menu > System Settings > Wi-Fi. Click Details next to the plane's network. 7. Read the values of Private Wi-Fi address and Limit IP address tracking. ## Comment corriger 1. Turn off the VPN until you are signed in. Also pause its kill switch, if it has one. 2. If the sign-in page does not appear, forget the network first. Then join it again from the Wi-Fi menu. 3. Forgetting the network removes its settings. Do it before the next steps, not after. 4. In the network's Details, turn off Limit IP address tracking. This also turns off Private Relay for that network. 5. Set Private Wi-Fi address to Fixed before you buy or redeem a pass. Do not change it after that. 6. If you use custom DNS, remove it for a short time. ``` sudo networksetup -setdnsservers Wi-Fi empty ``` Nécessite un mot de passe administrateur. 7. If a DNS profile is installed, remove it for the flight. Install it again after you land. 8. Dans un navigateur, ouvrez une page en http, pas en https. Par exemple, ouvrez http://captive.apple.com. 9. Sign in, or buy or redeem the pass, on the airline's page. Use the address only if the airline gives it. 10. If the pass is in use on the phone, log out there first, if the airline's page allows it. 11. After you sign in, turn on the VPN, Private Relay and your DNS again. ## Avec Kilobat 1. Check for a sign-in page with Kilobat's diagnosis. ``` kilobat diagnose --json ``` Résultat `measurements.captivePortal` vaut `true` quand le réseau demande une connexion. 2. Show the address of the sign-in page that the network sent Kilobat's check to. ``` kilobat portal ``` Output When a sign-in page is in the way, it prints its address. `kilobat portal open` opens it in your browser. 3. Si vous avez réglé le DNS avec Kilobat, revenez au DNS du réseau le temps de vous connecter. ``` kilobat dns automatic ``` 4. Changer de DNS nécessite un mot de passe administrateur. 5. For the provider, the price and how to connect on your airline, see [In-flight Wi-Fi by airline](https://kilobat.app/fr/in-flight-wifi). ## Questions **Why does my phone work when the Mac does not?** The phone often signed in first, or through the airline's app. It also often has no VPN, custom DNS or DNS profile. **What is the address of my airline's sign-in page?** It differs by airline and Wi-Fi provider. Use the address only when the airline publishes it. Otherwise open http://captive.apple.com. **Puis-je utiliser un VPN sur le Wi-Fi en avion ?** Turn it on only after you sign in. Airline rules for VPNs differ, and many airlines do not publish one. **Why do I have to pay again after I changed a setting?** The network can link the pass to the Wi-Fi address. A new private address or a forgotten network can look like a new device. ## Sources - [Apple Developer News : How to modernize your captive network (22 juin 2020)](https://developer.apple.com/news/?id=q78sq5rv) - [Assistance Apple : Utiliser des adresses Wi-Fi privées sur les appareils Apple](https://support.apple.com/en-us/102509) - [Assistance Apple : Gérer Relais privé iCloud pour certains sites web, réseaux ou réglages système](https://support.apple.com/en-us/102022) - [Assistance Apple : Modifier les réglages DNS sur Mac](https://support.apple.com/guide/mac-help/change-dns-settings-on-mac-mh14127/mac) - [Assistance Apple : Si votre Mac ne se connecte pas à Internet via le Wi-Fi](https://support.apple.com/en-us/101588) - networksetup(8), page man installée avec macOS 27.2 Vérifié le 29 octobre 2026. ## Guides associés - [La page de connexion Wi-Fi ne s’affiche pas sur un Mac](https://kilobat.app/fr/guides/captive-portal-not-appearing): Les réseaux publics bloquent souvent tout le trafic jusqu’à ce que vous vous connectiez sur une page de connexion. - [Adresse Wi-Fi privée sur un Mac](https://kilobat.app/fr/guides/private-wifi-address): Une adresse Wi-Fi privée remplace l’adresse MAC matérielle du Mac sur un réseau. - [Relais privé iCloud bloque certains sites web](https://kilobat.app/fr/guides/icloud-private-relay-sites): Relais privé iCloud fait passer le trafic de Safari par deux relais. - [Utiliser un DNS chiffré sur un Mac](https://kilobat.app/fr/guides/encrypted-dns-mac): Les requêtes DNS ordinaires ne sont pas chiffrées. - [Limiter le suivi de l’adresse IP sur un Mac](https://kilobat.app/fr/guides/limit-ip-address-tracking): Limiter le suivi de l’adresse IP est un réglage propre à chaque réseau. - [Mac connecté au Wi-Fi mais sans Internet](https://kilobat.app/fr/guides/wifi-connected-no-internet): Une connexion Wi-Fi n’est que le lien vers le routeur.
