If there are problems with the Bluetooth connection on the Apple Mac, this can have various causes. While Bluetooth is an ideal solution for short-range wireless connections with low battery load, the technology is not always error-free. What you can do about Bluetooth problems on the Mac, iMac and MacBook, I have put together for you in the following. If you know any other solutions, tips and tricks, please leave a comment under this post;)
Deactivate and reactivate Bluetooth
The trick is probably as old as electronic devices themselves: turn them off once and then turn them on again. This can also help with the Apple Mac's Bluetooth connection. You don't have to restart the computer itself, you can first deactivate the Bluetooth function under macOS and then reactivate it. This is particularly easy via the menu bar at the top of the screen. Simply click on the Bluetooth symbol, then on “Deactivate Bluetooth” and then on the symbol again and on “Activate Bluetooth”.
Remove USB devices and restart computer
In the event that the Bluetooth problems on the Mac are reflected in the mouse, keyboard or trackpad from Apple, the manufacturer has a corresponding one Support document released. For some connection problems, it recommends disconnecting all USB devices from the Mac and then restarting the computer. If you cannot establish a wireless connection, remove the mouse, keyboard, external hard drives, USB hubs, headsets, lamps and so on and reboot the computer. This can be a solution for the occurring Bluetooth connection problems.
Delete possibly damaged files
For the correct functioning of the wireless connection on the Apple computer, several files are required on the hard drive. In rare cases, these can be damaged by errors in the operating system. This then leads to the fact that you find bluetooth problems on the Mac. In the following guide I will show you how you can find the two possibly damaged files in order to delete them. Don't worry: after a restart, they are automatically recreated - error-free.
- Opens the Finder and click on “Go” in the menu bar
- Then select in the drop-down menu "Go to folder ..."
- Now give in the search window that opens / Library / Preferences and click on "Open"
- In the folder that opens you look for the file com.apple.Bluetooth.plist and delete them
- Now you repeat steps 1 and 2, but enter in the search window ~ / Library / Preferences / ByHost and click on "Open"
- In this folder you are now looking for the file com.apple.Bluetooth.xyz.plist (xyz = different letters, numbers and hyphens) and deletes them
- Reboots the Mac; now the bluetooth problem should / could be solved
Reset Mac bluetooth module
If you haven't been able to solve your Bluetooth problems on the Mac with the aforementioned steps, there is another one: Resetting the corresponding component in the computer. Don't worry here either: it's not unnecessarily complicated or anything. Here are the step-by-step instructions for this approach:
- Hold down the Shift key (⇧) and the Option key (Alt) while clicking on the Bluetooth symbol in the menu bar
- Now you can let go of the buttons, but you will still find the item "Debug" in the dropdown menu.
- Hold the mouse cursor over "Debug" and click "Remove all devices" in the list that appears
- Repeat steps 1 and 2, move the cursor to "Debug" and then click on "Reset the Bluetooth module"
- Now reconnects the devices that were previously removed from the device overview in order to use them as usual
Update 06.07.2020/XNUMX/XNUMX: SMC reset can also help
As my reader Georg told me in a comment, none of the procedures mentioned here did not help. In his case it was that SMC resetthat led to the goal. Here are the instructions on how to do this:
- Desktop Mac: Turn off the Mac, disconnect the power cord from the power supply for 15 seconds, then wait another 5 seconds and turn the Mac on again
- MacBook with removable battery: MagSafe-Remove the power pack, remove the battery, press the on/off button for 5 seconds, insert the battery, switch on
- MacBook with a fixed battery: Remove the MagSafe or USB-C power supply, Shift + Ctrl + Option (Alt) (everything on the left side of the built-in keyboard) and press the On / Off button for 10 seconds, release, plug in the power supply, switch on
Update 29.04.2020/XNUMX/XNUMX: Change WLAN or use DLAN
A reader has just told me (thanks, Walter!) That his Bluetooth problems were related to the WLAN. He switched his WiFi from 2,4 GHz to 5 GHz and the Bluetooth connections were working properly again. Another reader switched from 5 GHz to DLAN (network via the socket) and it was working again for him too.
It is relatively easy to test whether it is due to the WLAN by turning off the router and deactivating the WLAN on the Mac. If everything goes smoothly with the Bluetooth devices, you should continue researching in this direction.
Recommended DLAN modules are, for example TP-Link set of 2 TL-PA8030Pthat creates up to 1300 Mbit / s. Anyone who would like to open another WLAN in the target room via the DLAN can do so AVM Fritz Powerline 1260E / 1220E WLAN Set look, which you can even expand with the mesh points from AVM, if necessary.
Update 9.11.2022/XNUMX/XNUMX: Clean the battery contacts of the mouse, keyboard or trackpad
A tip just came in from my reader Peter. He had also had Bluetooth issues and a Bluetooth connection that kept dropping. It helped for him to clean the battery contacts. After that the connection problems were fixed.
My article on this subject also fitsMagic Mouse: Lost Connection - These Tips Will Help You ..." very good. It explains how to improve the contacts between the battery and the mouse.
