- Press Command-R at startup to try using the built-in Recovery system instead of Internet Recovery.
- Connect to the internet using Ethernet instead of Wi-Fi, or vice versa.
- Connect to the internet from a different Wi-Fi or Ethernet network. Your network configuration might not allow the internet access that macOS Recovery needs.
