Resetting Bluetooth Module on Mac: How to Fix Connection

Erik Blandford,

Macs like other devices use Bluetooth for wireless connecting with such things as mice, keyboard, trackpad etc. It is assumed to be a reliable way but sometimes there is a chance you have a problem when establishing a Bluetooth connection. Many of such problems may be easily fixed just by unpairing and changing batteries. After that reboot your Mac (use SMC reset) and done! But if it does not work, do not worry. A great way out will to reset network settings and here is how.

Quick Solution

There are two specific problems with connectivity that users usually experience:

  1. Bluetooth devices which are not able to pair with yours.
  2. Bluetooth devices that paired successfully, but are not working for some reason.

In both cases, the possible reason is the corruption of the preference list your Mac uses for storing Bluetooth devices and the present state of these devices. However, the fix is easy: create a backup of your data and just delete the bad preference list.

How to Reset Bluetooth Module

Before you proceed with resetting, remember that if your setup uses just Bluetooth to communicate with your mouse and keyboard, then you may temporary lose this connection (use the wired option if needed). So what should you do?

  1. Hold the shortcut commander Shift + Option (Alt), then press the Bluetooth symbol located in the top-right corner of the menu bar. (If you cannot find it there, then click Show Bluetooth in menu bar in your settings)
  2. Press Reset the Bluetooth module.
  3. Reboot your Mac.

That is it. As you can see, everything is easy. And what do you think?
