Cannot use AirDrop on my Mac running Yosemite I am trying to use AirDrop to copy some files to my iPad Air 2 but have some problems.

In my AirDrop folder, it never asked me whether I want to share it with Contact or Everyone. I have my ipad AirDrop turned on but it does not appear on my Mac's AirDrop folder. 

I have Wifi and Bluetooth turned on on both devices. This is what my AirDrop window looks like:



Can someone please help on this?
Your Mac may not meet the system requirements. At the bottom of this page, you'll see a list of the computers that support AirDrop.

(If your computer is one of the ones that should support AirDrop, please edit your question to say so.)
