To fix a blank Network settings page and a grayed-out Wi-Fi Details button on macOS, the issue is almost always a corrupted network configuration file or interference from background security tools. 


Follow these steps in order to clear out the glitch and restore your system settings:


Clear Corrupted Network Configurations

Deleting your local network preferences forces macOS to rebuild clean configuration files upon reboot.

  • Disconnect any external adapters and turn off your Wi-Fi from the control center menu bar.
  • In Finder, press Shift + Command + G on your keyboard to open the "Go to Folder" prompt.
  • Paste the following path exactly and hit return:
/Library/Preferences/SystemConfiguration/ 
  • Locate and select the following files (you may not have all of them):
    • com.apple.airport.preferences.plist
    • com.apple.network.identification.plist
    • com.apple.wifi.message-tracer.plist
    • NetworkInterfaces.plist
    • preferences.plist 
  • Move these files to the Bin / Trash. You will be prompted to enter your Mac's administrator password.
  • Restart your MacBook Pro. macOS will automatically recreate fresh versions of these files.


Check for Interfering VPNs or Network Filters

If you are using a VPN, third-party firewall, or antivirus, they often inject custom network filters that can break the System Settings UI. To bypass them temporarily: boot in safe mode. That process performs some system cleanup and clears caches, and also disables 3rd party extensions that may cause problems.

Start up your Mac in safe mode - Apple Support


If Safe Mode corrects the problem, then it might help to download and run EtreCheck, written by a long-time forum member. The free version is fine. Post the full report using the Additional Text button. No personal information is revealed. 



Re-add the Wi-Fi Interface via Terminal

Since the visual System Settings -> Network pane is completely blank, you cannot use the normal UI to fix it. If the steps above do not immediately bring the settings back, you can force-reset the Wi-Fi card using the command line: 

  • Open Terminal (found via Spotlight or in Applications > Utilities).
  • Type the following command to cycle the Wi-Fi interface down and press return:
sudo ifconfig en0 down
  • Type your Mac password (no characters will show as you type) and press return.
  • Turn it back on by typing:
sudo ifconfig en0 up
