For a smooth workflow, you need to connect accessories such as keyboard, mouse, microphone and headphones. Overall, it is a reliable technology. But at some point, you may have difficulty establishing a Bluetooth connection with one or more of your devices.

The easiest way to solve the Bluetooth connection problem is by unpairing and setting up the device from scratch. If the Bluetooth device still works with the Mac, read on to fix the problem.

1. Restart Your Mac

Let’s start with the basics. Often times, the most basic steps like restarting your Mac can fix a Bluetooth connection issue.

You can restart your Mac under Apple menu > Restart. It will fix almost any Bluetooth issue, especially those where the Bluetooth module crashes.

You should also remove all USB devices from the Mac and try your luck with the Bluetooth connection.

2. Reconnect the Bluetooth Device

If your device is not connected to your Mac, turn off your Bluetooth device and turn it back on to see if it reconnects. This is also a good time to check the battery level on your device. If it does not have enough power, charge it.

3. Restart Bluetooth on Mac

If your device doesn’t reconnect, you can restart the Bluetooth radio on your Mac. To do this, click the Launchpad icon in the Dock and go to System Preferences > Bluetooth.

Now click Turn Off Bluetooth and then Turn On Bluetooth.

If turning your Mac off and on again doesn’t work, turn your Bluetooth devices off and on again.

There is another reason to remove devices – if you are connected to too many devices this can cause connection problems. Although seven is said to be the maximum number of Bluetooth devices, you may run into problems when you go above three or four as some devices need more data than others.

Stage 1: Open System Preferences > Bluetooth.

Step 2: Click the x button next to each device and clear the Bluetooth device list.

Stage 3: Try connecting the Bluetooth device once again and see if it works.

7. Update macOS

I started noticing Bluetooth disconnection issues on my MacBook Air when I updated my device to the latest macOS Big Sur update. Apple is usually quick to fix such annoyances with future updates. If you are in the same situation as me, you should download the latest patch available from the System Preferences menu and install it on the device.
