If you see the globe and alert symbol, 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, 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.
