Magic Mouse 2 only connects with basic functions
I bought a new magic mouse 2 as the 5 year old one packed up and thought the recharge option better than replacing batteries. It connects to her macbook with bluetooth fine but only has the basic move and single click functions, mouse properties only shows basic none of the magic mouse functions. I connect to my macbook and everything is fine, swipe, double tap etc. Question is how do I get it to work on the other macbook when her old mouse worked fine before it broke.
MacBook Pro (15-inch Early 2011), OS X El Capitan (10.11.5)
