I have a macbook pro 15 mid 2012, 512mb videocard and an ipad mini retina. I was trying to use handoff and I could not find "allow hanoff" in system preferences. After digging it showed that my macbook pro is not supported. I tried to use yosemite continuity tool but it showed that my computer does not have support for bluetooth 4.0 but on everymac my macbook pro 15 mid 2012 is presented as having bluetooth 4.0. I am really lost. Your help is highly appreciated
