Many users complain about hearing static or cracking sounds from their Bluetooth headphones or speakers. Or, Bluetooth peripherals like the wireless keyboard, mouse, trackpad, etc., keep constantly disconnecting from their Mac. If you’re facing similar connection issues and have tried the basic troubleshooting steps, the last option is to reset the Bluetooth module on your Mac. In this guide, we’ll help reset Bluetooth on your Mac, regardless of the macOS version.
Importance of Bluetooth on Mac
Before we get into the importance of Bluetooth, let me brief you about Bluetooth. In simple words, Bluetooth is a wireless communication technology that allows you to pair devices and share data wirelessly. It shares data through the 2.4GHz wireless band. It is a cost effective technology solution that consumes very little power when transmitting data. The only drawback is that Bluetooth is meant for short distances and isn’t very effective for longer distances.
Today, there are various types of Bluetooth devices ranging from wireless headphones and speakers to keyboards, trackpads, and mice. These Bluetooth peripherals are convenient and look aesthetically better than their wired counterparts. Lastly, the primary purpose of Bluetooth technology on a Mac is to help you connect these wireless devices to your Mac.
Common Bluetooth Problems on Mac
Many users have connectivity issues with Bluetooth devices and ask questions like, “Why is my Bluetooth not available on Mac?”, “Why won’t my Bluetooth turn back on Mac?”, “Why is my Bluetooth not working?”, etc. The answers to these questions vary from device to device.
Firstly, the Bluetooth device might automatically disconnect from your Mac if it’s unused for a long period to save battery. If that’s the case, all you have to do is reconnect the Bluetooth device to your Mac.
Apart from this, you need to ensure that the Bluetooth device is compatible and has enough battery charge remaining to connect with your Mac. Then, you should keep the Bluetooth peripheral close to your Mac to avoid interference from other devices on the same 2.4GHz band.
It can get frustrating if the Bluetooth devices are still not working or if your AirPods are still not showing on your iPhone, even after you’ve followed these instructions. The only option we are left with is to reset Bluetooth on Mac. Read along to learn how to reset Bluetooth on any Mac.

Before we begin, please ensure that you have a wired (USB) mouse and or keyboard available with you.

Now that you’ve arranged a wired keyboard and mouse, you need to note that the steps to reset Bluetooth on Macs will depend on the macOS version. Regardless of which macOS version your Mac is on, we’ve got you covered. Read along to learn how to reset Bluetooth on Mac.
