Hi, I'm planning on purchasing a used MacBook in the next few days but want to know whether the model I'm planning on purchasing will support the new features announced in OS X Yosemite. The model is a MacBook Pro MD313LL/A 13.3-Inch, its the late 2011 MacBook Pro. Basically I want to know if Continuity will be supported and if the functions such as SMS and Calling from my macbook will be supported. So if anyone who has this computer or an older one is running 10.10 and can confirm they work or don't please let me know. Thanks!!
