One of the great news of the OS X Yosemite a set of features that Apple calls Continuity (Continuity), which integrate Macs even more with iGadgets. The problem is that they only work with recent machines, mostly models from 2012 to c.
Outraged by this limitation imposed by Apple, some users solved the problem by force and launched, via GitHub (open code), the Continuity Activation Tool. What it does enable the use of the Handoff, Instant Hotspot and AirDrop features in several models of Macs unofficially supported by Yosemite.
The list includes MacBooks Air from 2008 to 2010, Macs mini from 2009 to 2011, MacBooks Pro from 2009 to 2011, and iMacs from 2008 to 2011 only worth noting that some of them still require the replacement of your wireless card to enable the use of these resources via Wi-Fi and / or Bluetooth.
Despite the great promise, the tool has just been released and must still evolve a lot based on the feedback from adventurers who decide to test it. If you want to get into this, be sure to do a full backup from your Mac before via Time Machine or similar, since it alters system files. It also doesn?t work, at least for now, with dongles (USB) Bluetooth 4.0.
Perhaps the most annoying of all is the fact that even recent Mac owners have also reported experiences inconsistent with Continuity. Let's hope that Apple solves all the problems in future updates of OS X Yosemite and / or iOS 8, leaving the thing in tricks for everyone.
