How to Reset Network Settings on a Mac (macOS Step-by-Step Guide)
Your Mac’s network settings control how it connects to Wi-Fi, Bluetooth, Ethernet, and other network devices. Over time, these settings can become corrupted, often after system updates, software installations, or changes in network configurations.
If you’ve been dealing with:
- Unstable Wi-Fi that randomly drops
- Slow internet speed despite a strong signal
- Bluetooth accessories disconnecting without warning
- Network preferences not saving properly
…then resetting your network settings can often restore stable connectivity without requiring a full macOS reinstall.
Unlike iOS, macOS doesn’t have a single “Reset Network Settings” button. Instead, you’ll manually remove certain configuration files so that macOS recreates them fresh.
In this guide, we’ll cover:
- When you should reset network settings
- Different ways to reset them (basic & advanced)
- How to back up before making changes
- Troubleshooting tips if the problem persists
When Should You Reset Network Settings on a Mac?
Before you jump into resetting, it’s good to know when it’s actually necessary. Here are the most common scenarios:
- Wi-Fi Keeps Dropping
You’re connected but suddenly lose signal multiple times a day. - Unable to Join a Network
You keep entering the right password, but the connection fails. - Bluetooth Devices Won’t Pair
Your mouse, keyboard, or headphones stop connecting reliably. - Incorrect Network Details
Your Mac connects but doesn’t load websites, often due to DNS issues. - After a Major macOS Update
Sometimes, older preference files conflict with new system configurations.
Preparation Before Resetting
Resetting network settings deletes saved Wi-Fi passwords, custom DNS servers, and VPN configurations. Before you begin:
- Backup Wi-Fi passwords
If you use iCloud Keychain, they should sync automatically. Otherwise, check Keychain Access for saved credentials. - Note down VPN settings
If you use a VPN, record its configuration so you can restore it later. - Backup your Mac
Use Time Machine or another backup solution, just in case.
Method 1: Manually Delete Network Configuration Files
This is the most common way to reset network settings on macOS.
Step 1 – Close All Network Connections
Turn off Wi-Fi and Bluetooth. Go to Control Center or System Settings > Network and disable them.
Step 2 – Open the SystemConfiguration Folder
- Open Finder.
- Press
Command + Shift + Gto open “Go to Folder.” - Type:
- /Library/Preferences/SystemConfiguration/
- and press Enter.
Step 3 – Delete the Following Files:
Move these files to the Trash (you may need your admin password):
com.apple.airport.preferences.plistcom.apple.network.identification.plistNetworkInterfaces.plistpreferences.plist
Step 4 – Restart Your Mac
Once your Mac restarts, it will generate new default network configuration files.
Step 5 – Reconnect to Wi-Fi
Open System Settings > Network and join your network again.
Method 2: Reset Bluetooth (Optional)
If Bluetooth issues are part of your problem:
- Go to the same folder:
/Library/Preferences/ - Delete the file:
com.apple.Bluetooth.plist - Restart your Mac.
Method 3: Use macOS Safe Mode
Safe Mode clears caches and forces a fresh load of essential files.
- Shut down your Mac.
- Turn it on while holding Shift.
- Log in (Safe Mode will appear in the menu bar).
- Restart normally.
Troubleshooting After Reset
If problems persist:
- Update macOS — Some connectivity bugs are fixed in system updates.
- Check your router — Reboot it or reset its settings.
- Test another user account — If the issue doesn’t occur, it’s user-specific.
Pro Tips for a Stable Network
- Use 5GHz Wi-Fi for faster, more stable connections when available.
- Set a manual DNS server like Google DNS (8.8.8.8) for better reliability.
- Avoid using too many background apps that consume bandwidth.
