Bluetooth has become a part of our everyday lives, allowing us to stay connected with devices, appliances, and accessories.
MacBooks are some of the most popular computers, and they come equipped with Bluetooth capabilities that open plenty of neat opportunities.
Sure, you cannot connect MacBook Pro to monitor via Bluetooth, for example, but that is hardly a drawback.
Having said all that, however, this doesn’t guarantee that Bluetooth will work flawlessly every time you use it.
If you have experienced Bluetooth issues on your MacBook and are looking for ways to fix them, then you’ve come to the right place. Here, we discuss 13 common causes behind why the MacBook’s Bluetooth might not be working properly.
13 Causes Behind Bluetooth Issues on a Mac
1. Outdated software
It is possible that a MacBook’s software is too old or outdated for the latest version of Bluetooth.
Check for any updates available in the App Store and install them if necessary.
2. Faulty device drivers
The Bluetooth device drivers may be corrupted or too old due to which your computer isn’t able to connect to other devices via Bluetooth properly.
Try updating or reinstalling the device driver from the manufacturer website or using third-party software such as Driver Easy Pro to find the right driver for your device automatically without any hassle.
3. Not enough power
If your laptop isn’t plugged into an outlet it could be running low on battery which will cause it to struggle when attempting to connect via Bluetooth.
Plug in the laptop before trying again so that it can get enough power necessary for establishing a connection with other devices using Bluetooth.
4. Wrong settings
Check if all of your MacBook’s settings related to Bluetooth are correct and look for any discrepancies such as incorrect channel numbers or wrong passwords in the pairing process between two devices connected by Bluetooth technology.
5. Outdated firmware
The firmware on both ends (MacBook & Devices) should be updated regularly in order for a successful connection via Bluetooth technology;
Otherwise, there might be compatibility issues between different versions of firmware causing disconnections during transmission or even failure in establishing connections at all.
Make sure both end-points have updated firmware before connecting via Bluetooth wirelessly again.
6. Interference from other wireless signals
Interference caused by Wi-Fi networks or cellular services can cause disruptions to a solid connection through wireless technologies like Bluetooth;
Confirm that nothing else is transmitting data while trying to establish a connection between two end-points via wireless communication means.
7. Hardware problems
Overheating components or faulty hardware parts (like antennas) inside laptops can cause disruption during transmission over wireless technologies, including Bluetooth;
Immediately shut down the system and allow some time to cool off these components before turning it back on again.
This would help clear out any temporary hindrances imposed by overheating parts inside the laptop.
8. Malfunctioning/corrupted OS files
OS files related to Bluetooth operations can get corrupted due to viruses/malware infections leading towards malfunctioning of Bluetooth operations.
Run anti-virus scans regularly & keep updating virus signature databases so as to avoid these situations coming up unexpectedly again & again.
9. Obsolete hardware version
As technology evolves faster than ever these days, certain older versions of hardware components used in laptops become obsolete, resulting in incompatibility issues and, thus, failure to establish proper connections over Bluetooth.
Try replacing those old parts with newer compatible ones if necessary/possible.
10. Low signal strength
Weak signals due to either long distance between endpoints, improper placement/alignment of antennas, obstacles (e.g., walls), etc., can lead to dropped connections while transferring data.
Repositioning antennas/devices accordingly can help alleviate these problems successfully.
11. No access permissions given
Both endpoints involved need mutually-granted access permissions so that successful communication exchanges over Bluetooth can take place.
Check whether sufficient permissions were granted before setting up connections over Bluetooth.
12. Improperly configured profiles
The profiles configured on both ends must match each other perfectly; otherwise, disconnections will occur frequently.
Confirm that everything was properly configured.
13. Power saving mode enabled
Enabling the power-saving mode may hinder performance of wireless adapters, leading to unstable connections over Bluetooth.
Therefore, disable the mode, if necessary, when attempting data transfers.
Conclusion
These are some potential reasons why the Mac’s Bluetooth might not always work properly, but hopefully one of these tips should help you get back up and running quickly.
