Everyone knows your Mac is supposed to “just work”. Usually it is. But sometimes your computer may misbehave, especially when wireless technology like


Bluetooth

causes problems. Some users find that Bluetooth can even cause their MacBook or other Apple computer to freeze at startup, or Bluetooth itself to freeze or slow down. If you’re having a problem with your Mac because of Bluetooth, here are some common ways to troubleshoot and fix the problem.

Make sure your Bluetooth devices are fully charged

If you’re having Bluetooth performance issues on your Mac, the easiest thing to check is to make sure that any Bluetooth device you’re using, whether it’s your headset, keyboard, mouse, or other device, is fully charged. .

Update your macOS

It’s possible you’re using an older version of macOS and there’s a critical bug affecting your Bluetooth connections. To check, click on the Apple logo in the menu bar, then About This Mac. On macOS On screen, click Software update… If updates are available, click Update now.

Re-pair your Bluetooth devices

If you think the problem is with a specific Bluetooth device, you may be able to get it working properly again by unpairing the device from your Mac and then pairing it again. Click it Apple logo in the menu bar, then System Preferences… Double click Bluetooth. Find the potentially problematic device in the list, then click on the X on the right side of the window. In the pop-up window, click Eliminate. Then re-pair that device with your Mac and see if the performance has improved.

Improve your Bluetooth signal

Finally, you need to ensure that your Bluetooth devices have the best opportunity to communicate with your computer. If you’re using a Bluetooth device near the end of its range from the Mac, move closer. Keep the device as close to your computer as possible.

Also, make sure there are no other sources of potential interference nearby. If you have a Wi-Fi device connected to your Mac using the slower 2.4 GHz network, reconnect it using the 5 GHz Wi-Fi network if possible, to avoid interference with Bluetooth. Turn off any 2.4 GHz Bluetooth and WiFi devices you don’t need. And move all USB hubs away from your computer so they aren’t directly above or next to it.
