So the good news about this device is that it works as both a smart card reader and a memory card reader. I'm not sure if you can use it for both at the same time (as shown in the pictures) but at least individually it works. I was able to use it with macOS 10.12 (Sierra) on my MacBooks with forge.mil's Cackey software without any problems by following instructions from militarycac.com. It doesn't seem to require any additional special software to work with macOS as long as you have cackey installed and the required certificates. My only real complaint is that it *really* seems unreliable. I've had it for about three months now and have used it several times; Not sure if it will last all day with everyday use.
