Yesterday my eagerly awaited package was in the mail. I received my Atheros AR9271 USB WiFi Adapter that I ordered from AliExpress. A network interface that can easily be used with Kali Linux. Better yet, since it’s a USB adapter, it can be used within a virtual machine as a WiFi interface. Perfect! So we have everything we need to go from zero to Kali on a MacBook with external WiFi. Let’s get this up and running!
