Install TP-Link TL-WN822N on Mac

Playing with a high-gain antenna today on my Mac and had issues getting it to be recognised by the operating system. I’m running OSx El Capitan (v 10.11.5) and just plugging in the devices although working on my Windows Laptop refused to be see on the Mac.
To get everything up and running I needed to do a bit of Googling which lead me to this port, which had very little real detail so here are the steps I took.

1) Download the driver from the TP Link site (http://www.tp-link.com/en/download/TL-WN822N.html#Driver or go directly to the download (http://www.tp-link.com/res/down/soft/TL-WN822N(EU)_V4_160315_Mac.zip). 

2) Once you download the file, you should find another file "Mac OS X 10.7_10.10.zip”. Open this file and you get an installer and Uninstall.command file.

3) Download Pacifist and follow the instructions for the installation. Watch out for any of the attpemts to get you to sign up for things that you really don’t want. Once the application starts open the installer.pkg file
4) Select the "RtWlanU1827.kext” file and click
“Install” from the upper left hand corner of the dialogue.
5) Drag the "TP-LINK Wireless Configuration Utility” application to your
desktop.
6) Double click the "TP-LINK Wireless Configuration Utility” application
and the antenna details should appear.
