Connect iPhone to iMac (late 2012) with bluetooth

Hi all,

Somehow I cannot connect my iPhone 4S running verion 6.1.3 (build 10B329) to my new iMac 27" (late 2012 version) using Bluetooth.

After pairing I see that the iPhone device is not connected and when I press it to connect get a message on my iphone saying "...iMac is not supported".

I find hard to belive that a Bluetooth connection between iPhone 4S and the latest iMac is not supported at all.

fyi, I'm running Mountain Lion (10.8.4).

Thanks in advance.
