Though Bluetooth is sufficient and reliable technology, some owners of older Mac can still face difficulties. In order to completely solve the problem with pairing the devices, we have three effective ways.
To reset the Bluetooth module
Before you begin need to close all applications.
- Hold Shift + Alt and select the Bluetooth icon in the menu bar
- Select “Debug” -> “Reset Bluetooth”
- After that be sure to reboot the system
Check the Bluetooth, it should work. However, it is worth considering that all devices will need to be re-configured.
Delete the file Bluetooth settings
- Launch Finder
- Hold down the key combination Command+Shift+G
- In the window specify the following path: /Library/Preferences/
- Find files Bluetooth. They may be called “com.apple.Bluetooth.plist” or “com.apple.Bluetooth.plist.lockfile”, they are deleted
- Reboot, re-configurable pairing with the desired device
In most cases the first two methods is enough. However, if the problem still is the place to be, in this case, we can try the third method.
Reset the system management controller (SMC)
- Turn off our Mac
- Hold down Shift-Control-Option simultaneously with the power button for 10 seconds and release
- Include our Mac
SMC reset, have to check on the performance of Bluetooth.
