There are a lot of cool features coming to iOS 8 and OS X Yosemite this fall. One of the most hotly anticipated is Handoff, which enables you to pick up where you left off in an email, a document and other work between iOS and OS X devices. Handoff is elegantly choreographed dance between devices, operating systems and protocols.

It’s partly dependent on Bluetooth 4.0, the most recent widespread deployment of the popular short-distance wireless communication protocol, which includes Bluetooth Low Energy (BT LE). So, how can you tell if your Mac is properly equipped to take advantage of it?

You can check for yourself if you’re not exactly sure which Mac model you have. It’s a little convoluted, so bear with me and follow these instructions to find out.
