Why does Wi-Fi fail during Internet Recovery?

The recovery environment has a minimal network stack. Complex Wi-Fi configurations, enterprise auth, and captive portals often do not work.

How do I create a bootable macOS USB?

On another Mac: download macOS from App Store, then run sudo /Applications/Install\ macOS\ [version].app/Contents/Resources/createinstallmedia --volume /Volumes/MyUSB

Mac Error -2002F — Internet Recovery Connection Failed

Errorrecovery

Overview

Mac error -2002F occurs during Internet Recovery when the Mac cannot connect to Apple's recovery servers, preventing macOS reinstallation.

Key Details

Error -2002F indicates a network connection failure during Internet Recovery boot
Internet Recovery downloads a recovery image from Apple's servers
Requires a reliable, fast internet connection (preferably Ethernet)
Wi-Fi networks with captive portals (hotels, airports) typically do not work
Enterprise firewalls may block Apple's recovery server connections

Common Causes

Wi-Fi connection unstable or too slow for recovery download
Network firewall blocking Apple recovery servers (17.x.x.x IP range)
Captive portal Wi-Fi requiring web login not possible during recovery
DNS not resolving Apple's server addresses
Router incompatibility with recovery boot network stack

Steps

1Use Ethernet instead of Wi-Fi (use a USB-C to Ethernet adapter if needed)
2Try a different Wi-Fi network — avoid corporate or captive portal networks
3Use phone hotspot as a temporary internet source
4Reset NVRAM before attempting recovery: restart holding Option+Command+P+R
5Create a bootable USB installer instead: download macOS on another Mac and use createinstallmedia

Frequently Asked Questions

Yes, create a bootable macOS USB installer on another Mac using createinstallmedia. This avoids network dependency entirely.
