What is it? If you have a 13-inch MacBook Air or a 15-inch Retina MacBook Pro that only has Wi-Fi n, QuickerTek’s QCard2 is for you. It replaces your notebook’s Wi-Fi card, bringing 802.11ac speeds to Macs that are just that little bit too old to have it natively. You can fit it at home – all the tools you need are provided. When’s it due? Fit one now. Why are we excited? It’s a relatively cheap and fairly simple way to bring wireless ac connectivity to an older MacBook, but it’s only compatible with a limited range of models. To avoid disappointment, you’re best off checking with QuickerTek before you buy.
