Hello, I have a mid-2012 cMBP. I am running 10.9.4. I recently connected it to an external speaker using bluetooth, however recently deleted it because I didn't want it automatically connecting anymore. After deleting the speaker from my bluetooth preferences, I see it connecting to the speaker once in a while on its own. How do I stop it from connecting? I like to leave BT on for my wireless mouse (it is a BT one). Thanks!
