In that case, try these solutions:
- Make sure that your Mac can connect to the Internet. If you're not prompted to choose a Wi-Fi network during startup, move your pointer to the top of the screen, then choose a network from the Wi-Fi menu
, if available. - 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.
- Try again later, because the issue might be temporary.
- Start up from another disk or volume, if available, or use a bootable installer to reinstall macOS.
