The newest macOS update was just released, much to the delight of Mac users all over the world. macOS Big Sur comes with some new functions and an appearance that brings the world of macOS and the mobile iOS ever closer together.
But because the update is so recent, some common glitches are occurring upon downloading and/or installing Big Sur.
One of these issues is problems with the Bluetooth connection.
Let’s take a look at that here with some easy fixes you can use to get Bluetooth to function correctly on your computer.
Why Do I Have Bluetooth Problems After Installing macOS Big Sur?
There is no one exact reason why Bluetooth isn’t working for everyone after installing macOS Big Sur.
It could be caused by internal system problems that have been affected or altered after the update or an incompatibility with your Bluetooth device.
Either way, it’s a problem that you will want to fix quickly as many of us use one type of Bluetooth device or another almost every day.
Fix #1 – Make Sure Your Bluetooth Device is Turned On and Paired to Your Computer
We will start things off with the easy and obvious fix. The update may have caused your computer to forget a Bluetooth device that you had been using, and if so, you will need to pair it with the computer again.
The first step is to make sure that the Bluetooth device you want to use is turned on and within range of the Mac running Big Sur.
You’ll also want to make sure that the device is in discoverable mode, meaning other devices can recognize it.
To connect your Bluetooth device to your Mac, follow these steps:
- Click on the Apple menu
- Select System Preferences
- Select Bluetooth
- You should then see a list of available Bluetooth devices. Select your device from this list.
- Select Connect
- Your device will be connected to Bluetooth.
Your device should always be connected to your Mac after you go through the steps above the first time.
Meaning you won’t need to go through the steps above each time you want to connect. You can also connect by means of the Bluetooth icon from the menu bar on the top right of your screen.
Fix #2 – Restart Your Mac
Another quick fix to attempt if you can’t connect after following the steps above is simply resetting your computer.
You can go to the Apple menu and then select Restart from the drop-down menu.
This can fix some small glitches and is recommended whenever you are experiencing any minor technical difficulties such as problems with Bluetooth.
Fix #3 – Reset the Bluetooth Module
You can also reset the Bluetooth module on your computer to fix connection problems associated with the Big Sur update. This is another easy action that might help you resolve the issue.
To reset the Bluetooth module on your Mac, follow these steps:
Step 1: Hold down both the Shift and Option keys, and then click on the Bluetooth icon on the top right side of your screen.
Step 2: Select Debug.
Step 3: Select Reset the Bluetooth module.
Step 4: Select OK.
Step 5: Restart your Mac and your Bluetooth connection issues should be fixed.
Fix #4 – Move or Delete Bluetooth Extension File
If none of the above have worked, there is one more fix to attempt. This one involves going into your finder and locating a Bluetooth extension file and them moving or deleting it.
This has helped resolve problems associated with Bluetooth connection issues on Big Sur for some people.
It seems a little more complicated than the other fixes, but it really is another easy attempt.
To perform this fix, follow these steps:
- Open your Finder
- From the top menu bar, click on Go
- Select Go to folder from the Go dropdown menu
- Type in this text – /Library/Preferences
- Click the return key
- Locate this file – com.apple.Bluetooth.plist
- Delete that file or move it to a different location
- Restart your computer
- Attempt to connect to your Bluetooth device again
A properly working Bluetooth connection is a must for many of us.
If you experience problems with your Bluetooth connection after installing macOS Big Sur, run through all of the steps above, and you should be able to fix the problem quickly.
If none of the above fixes work, you can reach out to Apple customer support or explore their discussion board for other possible fixes.
Remember that a new operating system sometimes has a few glitches and issues that exist within early versions.
Keep an eye out for any additional updates to Big Sur, as this might help you resolve any small issues as well.
