A nifty tool that enables continuity features on macs that aren’t officially support by Apple. When I eventually upgrade to Yosemite, I may revisit this tool as my MacBook Air is one of the models that isn’t officially supported but meets all of the hardware requirements.
I would caution anyone interested in using this to only do so if you really know what you’re doing. This piece of software has to fiddle with low-level system files in order to enable these features. Make sure you have a known working backup before using the software on your mac.
