How to Reset Network Settings on macOS

Clear all saved Wi-Fi, VPN, and Bluetooth settings when connectivity repeatedly fails.

Last verified: February 21, 2026

macOS doesn't offer a single Network Reset button the way iOS does — the equivalent is manually deleting the network preference files stored in /Library/Preferences/SystemConfiguration/, which forces macOS to recreate them with defaults on next boot. These files include NetworkInterfaces.plist, preferences.plist, and com.apple.airport.preferences.plist, and their removal resets ethernet, Wi-Fi, and VPN configurations simultaneously. The approach requires administrator access and is best preceded by noting your current DNS settings, VPN configurations, and static IP setups if any, as these won't be preserved through the reset.

Before you continue

Network reset removes all saved Wi-Fi passwords, VPN profiles, and paired Bluetooth devices. Record them before proceeding.

Quick Steps

Follow in order for the fastest result.

  1. 1Open System Settings > Network. Remove VPN and Wi-Fi interfaces. Delete network preference files from /Library/Preferences/SystemConfiguration/, then restart.
  2. 2After the restart, reconnect to your Wi-Fi network by entering the password.
  3. 3Re-configure any custom DNS, VPN profiles, or Bluetooth accessories.

Frequently Asked Questions

What does resetting network settings on macOS delete?
Resetting network settings removes all saved Wi-Fi networks and passwords, Bluetooth pairings, VPN profiles, custom DNS settings, and cellular APN configs. It does not delete your apps, photos, messages, or personal files.
Will resetting network settings fix my Wi-Fi on macOS?
It often does when all other steps fail. It resolves issues caused by corrupted network profiles, misconfigured DNS, dead VPN residue, and conflicting network adapter settings. After the reset, reconnect to Wi-Fi from scratch — treat it as connecting for the first time.
Do I need to reset network settings to fix a slow connection on macOS?
No — network reset is a last resort. For slow connections, first restart the router, check for background downloads, test with a VPN disabled, and change DNS to 8.8.8.8. Only escalate to a full network reset if the targeted fixes don't work.
How long does resetting network settings take on macOS?
The reset itself takes under 30 seconds. The required restart adds 1–2 minutes. Reconnecting to Wi-Fi and re-entering passwords takes a few additional minutes. Total time from start to fully connected is typically 5–10 minutes.
