One of the situations we experienced when Apple made the new OS X Yosemite available to users was how thousands of them put their hands in their heads when they learned that one of the star features of the new system, the ability to integrate iOS devices with OS X using Continuity and Handoff was not supported on all Macs.
Criticisms and posts on Apple's solutions forums quickly began to surface, but the idea was nevertheless clear, as non-compliant computers couldn't use Continuity. This incompatibility only came from the type of Bluetooth that the Mac had.
Continuity, the protocol through which we can send and receive phone calls on devices with iOS 8.1 and OS X Yosemite, has a limitation and is that it can only be used between devices that have Bluetooth 4.0 LE (Low Energy).
However, it didn't take long for some developers to find a solution that they called Continuity Activation Tool. This tool simply tricks the system into believing that we do have Bluetooth 4.0 LE on the Mac and thus be able to use Continuity.
However, in the beginning this tool, in the case that your Mac was very old and did not have Bluetooth 4.0, it was necessary to install a new wireless card. Now with version 2.0 of Continuity Activation Tool the process is simplified and it is already possible use a simple dongle Bluetooth 4.0, or what is the same, a USB stick that adds Bluetooth to the computer.
However, not all devices that are sold are indicated. The developer of the tool advises that the necessary ones must be based on the chip Broadcom BCM20702, similar to those used by Apple on Continuity-compatible Macs.
It should be noted that if we are going to make the purchase of this product, we have to know that the Instant Hotspot does not work quite well. To download the tool click on the following link.
Well, I can make and receive calls on a macbook pro mid 2009 as well as an iMac 27 from mid 2010… I haven't tried the rest.
Salu2.
