How to Fix Mac Bluetooth Problems Easily

Apple began a revolution in technology that few companies could match, which is the reason why everyone loves its product and why it has become the epitome of technology. Though iPhones take up all the hype, Mac devices are the ones that are mostly used. Nowadays, in every big office, school, corporate house, household, and more, you will see a Mac device. Why? Because Apple aims to provide its users the most hassle-free experience with high efficiency and offers some features that rival companies cannot. But nothing is perfect, sadly. Mac devices have some issues of their own, Bluetooth ones being the oldest and most persistent one. If you own a used a Mac device and have not faced Bluetooth problems, you are lucky! We will give you the effective ways to answer how to fix Mac Bluetooth problems.

Mac and Bluetooth, fighting like a married couple.

Though this sounds funny, it actually is not, trust me. Bluetooth problems have always existed in Mac devices and though we love Mac, we cannot deny the fact that Bluetooth issues are really annoying and often very stubborn! Before we discuss how to fix Mac Bluetooth problems, let’s first see what these problems are. Most of the time, the problems you will experience are going to involve third-party accessories and apps using Bluetooth to transmit information to and from devices. These are usually connectivity problems when the device is listed as connected or may not even appear in the list of Bluetooth devices at all and they are often even known to, unfortunately, affect Apple’s own keyboard and mouse accessories. Beware.

Now that we have discussed the issues, let’s see how to fix Mac Bluetooth problems:

Method 1. Try to turn on and turn off

If you ask anyone what to do if your Bluetooth is not working in Mac, this is the first and most common solution you will get. Although it seems like a broken record, do try it. You can easily switch Bluetooth off and on from the Bluetooth icon in your Mac’s Menu Bar.

Once you have turned Bluetooth off and on again, see if its connectivity works. If it does not, take the reboot to the extreme and try rebooting your Mac. Click on the “Apple” menu in your Menu Bar and choose “Restart”.

After rebooting, try to connect your Bluetooth devices again. I hope this will answer your question to know how to fix Bluetooth problems on your Mach.

Method 2. Remove Bluetooth preference files

Still thinking what to do if your Bluetooth is not working? If the previous solution did not help, this might. You may not know, but there are some files that your Mac creates to manage its Bluetooth connectivity. If you are wondering how to fix your Mac Bluetooth issues, try this method as it has the highest success rate. Don’t fret, just follow these easy steps:

  1. Launch Finder and press “Command + G”. This will fire up the “Go to Folder” dialog box. You can also access it by clicking on Go in the Menu Bar.
  2. In the dialog box, type - /Library/Preferences, and hit Enter.

  5. After that, press Command + G again and type – “~/Library/Preferences/ByHost/”. You can also type – “/Users/username/Library/Preferences/ByHost/”. In the directory that opens, a file will appear whose name begins with “”, followed by a bunch of mixed numbers and letters. Delete this too.

Once you have done all this, reboot your Mac. Turn your Bluetooth on manually if it has not already been switched on automatically, and now it should work properly. Fingers crossed, I hope this answers your question of what to do if Bluetooth is not working on your Mac.

Method 3. Reset the Mac Bluetooth module.

Previous solutions did not work? Still thinking what to do if Bluetooth is not working on your Mac? Let’s try this method and hope it solves this annoying problem.

This should be your last option in case the above-mentioned solutions have not worked. Resetting the Mac Bluetooth module is often a good approach to troubleshoot the stubborn Bluetooth issues, using the little-known ‘debug menu’ option. Before you take upon this task, do remember that this will disconnect every Bluetooth device on your Mac. Let’s take a look at the following steps to reset Mac’s Bluetooth module: -

  1. From your Mac desktop, hold down the Shift + Option keys and then click on the Bluetooth menu option. This will reveal to you the hidden Debug menu.
  2. Now, select the “Reset the Bluetooth module” option from the debug menu list.

Although we all love using our Mac devices and always look forward to purchasing the new ones, issues like Bluetooth connectivity really hit a nerve and I am sure you all will agree. Bluetooth is a feature which we use every day and issues like this get in the way of our hassle-free experience. Apple’s Bluetooth framework is due for a much-needed overhaul but until that happens, the best we can do on our part is to troubleshoot the problems as they occur, and solve them so that we can start using our beloved Bluetooth apps and accessories again. So, if you have faced or are facing Bluetooth problems in your Mac device and are thinking what to do if your Bluetooth is not working on Mac, go through these methods to try and solve your problem. Don’t worry, you do not have to be a tech expert to carry them out, just follow the easy steps and voila! Your work is done and dusted. All the best!
