How to solve the problem that a bluetooth device not always auto connects

I have been irritating me about my mouse not connecting when I turned it on, the problem seems to be solved by adding the device as a favorite in the bluetooth settings.

 

First goto System Preferences:

Path:  » System Preferences…

 

Then goto the Bluetooth panel

Path:  » System Preferences… » Bluetooth

 

Select your device and click the gear at the bottom, there click Add to favorites.

This was my solution 🙂
