How To Disconnect Phone From Mac [Easy Way]

As a result of the Apple ecosystem, all your devices are seamlessly connected. The perfect integration between Macs and iPhones highlights this unique interdependence. How do you avoid them working together if you don’t want them to? You don’t need to worry! Separately using your Mac and iPhone is always an option.

If you previously set them up to work together, you would need to disconnect them manually. Several methods exist for disconnecting your iPhone from your Mac, so I’ll walk you through them. Let’s get started!

Step 1. Restart your Mac and Bluetooth device

When Bluetooth does not work properly, it is sometimes advisable to restart your computer system just like any other. In other words, you should turn off both your Mac and your Bluetooth devices. This is often the most effective solution if your Mac says that a Bluetooth device is unavailable.

  • On your Mac, open the Apple menu and click Restart. Then confirm you want to Restart
  • For your Bluetooth device, look for a power switch or follow the manufacturer’s instructions to restart it

Step 2. Turn your Mac’s Bluetooth off and on

The Bluetooth settings on your Mac may need to be restarted if restarting doesn’t help.

If you’re using macOS Monterey or Big Sur:

Click the Control Center icon in the menu bar > then click the Bluetooth icon to toggle it off and on.

If you’re using macOS Catalina or earlier:

Go to System Preferences Bluetooth and click Turn Bluetooth Off.

Step 3. Forget and reconnect your Bluetooth device

It is common to encounter Bluetooth connection problems after updating macOS or replacing batteries in your devices. The reason for this is that these actions can result in the emergence of new software problems. The easiest way to fix them is to disconnect your devices from your Mac and pair them again.

The most effective way to disconnect a Bluetooth device is to tell your Mac to forget it.

Follow these steps to do that:

  1. Go to System Preferences > Bluetooth
  2. Click to select one of your Bluetooth devices
  3. Click the X icon on the right, then confirm you want to Remove the device
  4. Repeat these steps for each Bluetooth device on your Mac

After telling your Mac to forget a Bluetooth device, connect the Bluetooth device again, just like when you first used it.

Step 4. Delete the Bluetooth preferences on your Mac

If your Bluetooth devices are still not working, there might be an issue with the Bluetooth preferences list on your Mac. These PLIST files can get corrupted over time, causing problems with various wireless connections.

Follow the steps below to delete the Bluetooth preferences list from your Mac, forcing it to create a new file. After doing this, you may need to connect your Bluetooth devices again.

Here’s how to find and delete the Bluetooth preferences list from your Mac:

1. Open Finder and select Go > Go to Folder from the menu bar

2. Type /Library/Preferences/ and click Go

3. You will need to find the following files (you may not have both of them):

  • plist
  • com. apple.Bluetooth.plist.lockfile

4. Drag these files to the Desktop to create a backup copy of them. This is helpful in case you need to restore these preferences later

5. Back in Finder, drag the original Bluetooth preference files to the Trash

6. Enter your Mac administrator’s password to confirm

7. Restart your Mac to generate updated PLIST files

If your wireless Bluetooth device still doesn’t work with your Mac, move the PLIST file from your desktop to the Preferences folder. You will need to agree to replace the outdated file. This will restore your old Bluetooth preferences.

Step 5. Debug your Bluetooth connections

The next step is to delete all Bluetooth devices from your Mac and re-configure them. Bluetooth preferences allow you to do this by selecting the Debug option. However, you may want to create a backup of your Mac first to ensure you don’t lose any sensitive Bluetooth data.

How you find the Debug menu depends on your Mac’s operating system.

If you’re using the latest macOS Monterey, the only way to debug Bluetooth is by using Terminal: 

  1. Open Terminal
  2. Paste the following: sudo pkill bluetoothd
  3. Enter your admin password

If you’re using Big Sur, follow these steps to reveal the Debug menu:

  1. Open the Control Center from the menu bar
  2. Hold Shift + Option on the keyboard
  3. While holding both keys, click the word Bluetooth
  4. The three Debug options appear beneath your Mac’s Bluetooth information

If you’re using macOS Catalina or earlier, follow these steps to reveal the Debug menu:

  1. Go to System Preferences > Bluetooth
  2. Enable the option to Show Bluetooth in the menu bar
  3. Hold Shift + Option on the keyboard
  4. While holding both keys, click the Bluetooth icon in the menu bar
  5. Hover your mouse over the Debug option

After opening the Debug menu, you should see the following three options:

  • Reset the Bluetooth module
  • Factory reset all Apple devices
  • Remove all devices

We suggest you try each option, one at a time. After choosing to Reset the Bluetooth module, connect your Bluetooth devices to test if your Mac still says they’re unavailable.

If your Bluetooth devices still aren’t working, move on to the next Debug option, test again, and go on to the final option.

Step 6. Troubleshoot your particular Bluetooth device

You can use a huge range of Bluetooth devices with your Mac. Depending on your device, you might need to follow different troubleshooting tips to fix your Bluetooth problems.

For example, in our guide on how to fix wireless mouse problems, we go into detail on changing the scrolling or tracking settings, but that won’t be very helpful if you need to troubleshoot some Bluetooth headphones.

Try to find specific troubleshooting suggestions for your device to fix any lingering Bluetooth issues.
