 ## So why should you upgrade your MacBook if it is a decade old?
 Well if you're like me and don't want to shell out a lot of money for one of Apple's new offerings, this upgrade can allow you to hold on to your MacBook for longer. With this upgrade, you get a newer version of Bluetooth 4 which allows you to use AirDrop and connect to most modern devices. You also get a much faster WiFi unit which can allow you to achieve speeds of over 1 Gigabit and take full potential of your home network.
