Big Sur Bluetooth not working – Explained

Bluetooth problems on macOS Big Sur have become a common issue for some Mac users. A number of people have reported that they are having trouble with their Bluetooth devices and their connection to the computer.  The issue revolves around the fact that the Bluetooth headphones or speakers connect well, but then they don’t play any sound. Other users have been reporting that the connection keeps dropping suddenly.

As per the reports, the macOS Big Sur Bluetooth problem is equally common with third-party Bluetooth accessories, as well as Apple’s own peripherals like the Magic Mouse, Magic Keyboard, Trackpad, and even with the popular AirPods and AirPods Pro wireless earbuds.

That’s why if you are a happy owner of a brand new Mac computer that doesn’t want to connect to your Bluetooth accessories or your wireless mouse, keyboard or headset are suddenly disconnecting from macOS Big Sur, don’t throw it out of the window yet. In this post, we will offer you an easy way to overcome this common macOS 11.0.1 problem.

Many Mac users, just like you, have documented issues with their Bluetooth devices after Big Sur has been upgraded.  Some have been complaining that they manage to connect the peripherals, but the connectivity is very laggy and poor, or the devices disconnect unexpectedly.

If you have spent a lot of time with Apple support on the same problem and you have already tried every possible fix on the internet, don’t get despaired.

Here we will offer you some quick fixes and workarounds that you can try to improve this situation:

Solution for Big Sur Bluetooth Problem

  1.    Firstly, on your Mac, press the Shift + Option keys from the keyboard.
  2.     Then, click on the Bluetooth icon that is found in the menu bar.
  3.     Next, select Reset the Bluetooth module and confirm the action by clicking on Ok.
  4.     After that, restart your Mac computer and see if the issue has been resolved.

If the instructions above do not help, you can try to delete all plugins that are found in the following directory:

/Library/Audio/Plug-ins/HAL/

After that, restart your Mac again. The Bluetooth issue should be fixed.

    Sorry, doesn’t help. I’m now on Big Sur 11.4 and my Apple keyboard still disconnects or lags all throughout the day (and its is approx 30-40 cm’s from my Mac mini), as well as my Logitech mouse (which I now use with the RF receiver instead). This is a real bummer. I tried to downgrade to Catalina, and the problem went away. Then updated to Big Sur again after af couple of .1 updates, thinking that NOW the issue must have been fixed, but no.

      Hi, Peter, did downgrading to Catalina really fix the bluetooth issue? I’ve never changed OS’s- does one lose anything? My Mac Magic keyboard never ONCe disconnected from my old iMac in 7 years, and all my same bluetooth devices work fine with everything else in the world except this brand-new MacBook Air M1 which so far has made me want to literally smash it against the wall every single day, but not before very entirely useless Apple “helper” is either trained to help or sent somewhere else on the e-planet.

    Bluetooth has been a Mac issue for a very long time, along with their crappy Mac Mail program. There seem to be certain sections of the OS that Apple just ignores, despite being a Trillion dollar company. Why don’t they throw a bunch of money and coders at these problems and fix them?

    I’ve tried all the fixes in the past, on almost every version of MacOS. Reset BT prefs, zapping PRam, reset NVRam, reset SMS, or delete Library folders, running terminal commands… sometimes it works for awhile, other times nothing.

    Very frustrating, it’s like Apple treats Mac as an ugly red-headed stepchild, behind their iOS products.

    Fuck you Apple! Crappy Mail, crappy Bluetooth! WAY overpriced for the POOR SERVICE! Cannot even pair any BT device. If it works on a 500$ laptop, then why doesn’t it on a 3000+$ one??? Where’s the premium??? This has been lasting for YEARS now and I HAVE HAD IT!
