Control phone on MacBook Pro via bluetooth?
A similar question was posted entitled "Software to control mobile phone via bluetooth" over at Superuser.com on 11th December 2012 to which I responded:

My response was this:

A program called Remote Professional from mobileways.de claims to be able to make calls from your PC-mobile. There is a brief article about it entitled Remotely Control Your Phone from Computer from Technize.com

A youtube video and link to download the program is also included: http://www.technize.com/remotely-control-your-phone-from-computer/

However this method used a PC rather than an Apple Mac. It may well be possible that mobileways.de offer a similar program for Macs.

So in theory what you have asked is perfectly plausible, if they haven't developed a program for apple macs, they may do in the near future.
