There is no denying that Bluetooth technology has made data sharing so much easier. Bluetooth is used mainly with features like continuity, transfer, file sharing, and more. And there are iBeacons and various other technologies that rely on Bluetooth LE.
Sometimes, a “Bluetooth not available” message appears on your Mac, and it won’t connect. In addition, some Mac users may find Bluetooth functionality affected, often after restarting or updating OS X.
The first noticeable sign is that it doesn’t detect any hardware that uses Bluetooth.
These can include a keyboard, mice, headset, or any other Bluetooth device that you use. When you open the Bluetooth icon in the menu bar in “About this Mac,” it marks the error: “Bluetooth Not Available.”
This error can be annoying if you’re a fan of wireless since you can’t connect anything.
Now, we’ll look at your Mac’s Bluetooth capability, where to turn this feature on, how to pair a new device and possible Bluetooth connectivity issues.
System Preferences of Macbook Pro
Do you know how to turn on Bluetooth, pair a new device on Mac? Are you aware of why the “Bluetooth Not Available Error” occurs in the first place?
Read on to discover all system preferences Bluetooth of your Mac followed by 7 Fixes of the “Bluetooth Not Available” Error!
Does Macbook Have Bluetooth?
Every new Mac you buy has Bluetooth. So there is no need to buy any extra hardware on your MacBook Air/ Pro or iMac to use Bluetooth.
Suppose you can’t see the Bluetooth in your panel of System Preferences. In that case, you probably have an old Mac which doesn’t support Bluetooth. You can buy an adapter for your device.
Make sure you purchase the one compatible with mac OS because mostly, these are made specifically for Windows.
How to Turn Bluetooth On?
To turn Mac Bluetooth On:
- Open the menu of the Apple icon in the left corner of your screen.
- Select System Preferences Bluetooth.
- Select Bluetooth in the menu bar.
- On the Bluetooth panel, there will be a Bluetooth icon on the left side.
- Here the Bluetooth will be Off. Click on the “Turn Bluetooth On” button.
We also suggest you check the box called ‘Show Bluetooth’ if it does not enable from this panel.
It has a Bluetooth icon at the top that allows you to access mac Bluetooth connections instead of hitting the panel.
Connect Devices Supporting Bluetooth Connection to Mac
Before a Bluetooth-enabled device can connect with the Mac, you must pair it first.
If you turn Bluetooth on any device back, you will be well-known for the idea of visibility.
It is now standard for multiple Bluetooth devices to appear in the same area.
So, it would be best if you paired the devices for security manually. You may do this when the device is visible.
Pairing New Devices
The features of this process vary depending on the devices you need to connect with.
Like macOS, many other OS such as Windows 10, Android, and iOS visible when you turn on the Bluetooth.
- When the device you are connecting to is in connecting mode. Its name should appear under the devices heading in your Mac’s Bluetooth settings.
- Click on Connect button.
- When pairing a Bluetooth device for the first time, you may have to confirm a PIN on both devices. If you need to enter the PIN manually (seen on older devices), this is probably 0000, 1234, or 1111.
- After this is done, you have connected your device to Mac by Bluetooth.
When both devices are powered on and within the limit of each other (around 9-10 meters), they connect automatically.
In case your devices don’t connect automatically, you can always do this manually.
You can see the devices you have previously paired with under Devices in the Bluetooth settings panel (besides the menu bar icon). After making sure the device is turned on, click its name to connect.
Remove Bluetooth Device
To remove all devices on Mac:
- Go to library preferences
- In system preferences, click the device name in the device list
- And select Uninstall.
Once you uninstall library preferences, the device will no longer connect automatically. Instead, you will need to pair it again to use it.
What’s the Root Cause of the “Bluetooth Not Available” Error?
All those who own a Macbook must have faced the random interruption of the Bluetooth function on their laptops.
What happens to your laptop that makes you aware of this dilemma? And more importantly, what’s the cure?
First things first, all the devices connected to your laptop via Bluetooth tend to stop working. From earphones to keyboards, the hardware becomes unresponsive.
The first thing any person would do will be to check for the Bluetooth settings in the respective devices.
While you are doing so, if a message stating “Bluetooth not available” pops up, it means that either your Macbook or your hardware is subject to some error.
As you have deduced that there is a problem, now is the time to find the culprit. First, you need to open the Apple System Profiler from the Bluetooth settings in the Hardware tab.
If it shows “No information found.”, then we’re afraid this could be a severe problem.
Simple disconnection problems can be solved by either replacing the device batteries or turning toggling the on and off the Bluetooth settings.
There are plenty of macOS-specific ways to solve the problem of Bluetooth not available.
For starters, you can start by deleting all your Bluetooth preferences and then reconnecting the hardware. Hopefully, this should resolve the issue.
However, if it does not, then you’re in for some more trouble! You’ll be required to do the reset at a larger scale according to the hardware attached.
In that regard, allow us to show some of the most successful methods to eliminate this dilemma.
