AC1200 isn't a model, its a speed. If you mean the A6210, then the minimum requirements for it are windows OS. its not compatible with Mac OS. 

If you go to netgear.com/support/    and type in your model number. it'll have the product data sheet that shows minimum requirements. This shoud have whether its compatible with your device.
