Disconnect Wi-Fi Network Mac: 2 Ways

To disconnect a Wi-Fi network on a Mac, you can either turn off Wi-Fi entirely from the menu bar or “Forget” the network so your Mac stops auto-joining it. If you just want to stop connecting to one specific network temporarily, you use the “Forget This Network” option in System Settings; if you want to cut all wireless connections at once, you toggle Wi-Fi off. This article covers both methods, what each does, and how to reconnect when you need to.

Why Disconnect vs. Forget

Many Mac users confuse “disconnect” with “forget.” Disconnecting means your Mac drops the current connection but still remembers the network’s password and settings, so it will automatically join again when the network is in range. Forgetting removes the network from your saved list entirely—your Mac won’t auto-join, and you’ll need to re-enter the password to reconnect. Choose based on your goal:

• Disconnect temporarily – you’re leaving your desk and want to save battery, or you’re troubleshooting a slow connection.
• Forget permanently – you no longer trust the network, you’re selling your Mac, or you want to force a fresh connection to fix a stubborn issue.

How to Turn Off Wi-Fi on a Mac

The quickest way to disconnect from all Wi-Fi networks is to turn off the Wi-Fi radio entirely. This stops your Mac from scanning for networks and drops the current connection instantly. Here’s how:

1. Click the Wi-Fi icon (the fan-like symbol) in the menu bar at the top-right of your screen.
2. Select Turn Wi-Fi Off from the dropdown menu.
3. To turn it back on, click the same icon and select Turn Wi-Fi On.

Alternatively, you can go to System Settings (or System Preferences on older macOS) → Wi-Fi and toggle the switch off. Turning Wi-Fi off is the most complete disconnect—your Mac won’t join any network until you re-enable it.

How to Forget a Specific Wi-Fi Network

If you want to stop your Mac from auto-joining a particular network (like a neighbor’s router or a public hotspot you used once), you should forget it. This removes the network from your saved list, so your Mac won’t connect to it automatically. Here’s the step-by-step:

1. Open System Settings (click the Apple menu and select System Settings).
2. Click Wi-Fi in the sidebar.
3. Scroll down to the Known Networks section (or “My Networks” on older macOS).
4. Find the network you want to forget, click the “i” icon next to it, then click Forget This Network.
5. Confirm when prompted.

After forgetting, your Mac will no longer auto-join that network. To reconnect later, you’ll need to select the network from the Wi-Fi menu and enter the password again.

What to Do if the Wi-Fi Menu Doesn’t Show

If you don’t see the Wi-Fi icon in the menu bar, it might be hidden. To show it:

1. Open System Settings → Control Center.
2. Under Menu Bar Only, find Wi-Fi and choose Show in Menu Bar.

If you still can’t see it, your Mac might have a hardware issue or Wi-Fi might be disabled in System Settings. Check that the Wi-Fi toggle is on in System Settings → Wi-Fi.

Common Problems and Fixes

Sometimes disconnecting or forgetting doesn’t work as expected. Here are typical issues and solutions:

• Wi-Fi keeps reconnecting after you forget – This can happen if the network is saved in another location, like your iCloud Keychain. Go to System Settings → Wi-Fi → Known Networks and make sure it’s gone. If it reappears, check your Keychain Access for saved passwords.
• You can’t forget a network – On some macOS versions, you need to click the “i” button next to the network first. If the option is grayed out, restart your Mac and try again.
• Turning off Wi-Fi doesn’t disconnect – If you’re using Ethernet or a VPN, your Mac might still show an internet connection. Turning off Wi-Fi only disables the wireless adapter; other connections remain.

Frequently Asked Questions

How do I disconnect from a Wi-Fi network without forgetting it?

Simply turn off Wi-Fi from the menu bar. That drops the connection but keeps the network saved. When you turn Wi-Fi back on, your Mac will automatically reconnect to the same network if it’s in range.

Will forgetting a Wi-Fi network delete the password?

Yes, forgetting removes the saved password for that network from your Mac’s keychain. You’ll need to enter it again to reconnect. If you have iCloud Keychain enabled, the password might still be stored in your iCloud account and could sync back to your Mac.

Why does my Mac keep joining a network I forgot?

This usually happens because the network is also saved in your iCloud Keychain or because your Mac is set to auto-join “known” networks. Check System Settings → Wi-Fi → Known Networks and remove it there. Also, go to System Settings → Apple ID → iCloud → Keychain and turn off Keychain syncing temporarily to prevent it from re-adding.

How do I disconnect from a Wi-Fi network on a MacBook with a Touch Bar?

The process is the same. Use the Wi-Fi icon in the menu bar or go to System Settings. The Touch Bar doesn’t change the steps; it just provides a shortcut to toggle Wi-Fi on some models.

What’s the difference between “Turn Wi-Fi Off” and “Disconnect” on a Mac?

There is no separate “Disconnect” option in macOS. “Turn Wi-Fi Off” is the only way to manually disconnect from all networks. Forgetting a network is the only way to stop auto-joining a specific one.

Can I disconnect from a Wi-Fi network using Terminal?

Yes, advanced users can use the networksetup command. For example, networksetup -setairportpower en0 off turns off Wi-Fi. To forget a network, use networksetup -removepreferredwirelessnetwork en0 "NetworkName". This is useful for scripting, but the GUI method is simpler for most users.

Reconnecting After Disconnecting

To reconnect to a network you’ve forgotten, click the Wi-Fi icon in the menu bar, select the network, and enter the password. If you only turned off Wi-Fi, just turn it back on—your Mac will automatically join the last used network if it’s available. If you’re having trouble reconnecting, try restarting your Mac or your router, and ensure your Wi-Fi is enabled in System Settings.

Remember, disconnecting is temporary, forgetting is permanent. Use the right tool for your situation, and you’ll have full control over your Mac’s wireless connections.
