Install Alfa Wifi AWUS036H on OSX

So you are an Apple freak but you do admit that our macbooks have a really weak wifi connectivity. You must have also purchased one of the best USB wifi adapters, the Alfa AWUS036H and find out that it is not compatible with Snow Leopard or later... Worry not, today I have managed to install this Wifi interface and I am really enjoying it's massive signal boost. I will teach you how I did it.



  1. Download the Realtek 8187L from Alfa website or your CD media. Note that the driver must be for OSX 10.5 or later.
  2. Unpack the zip file and install driver by double clicking the install.pkg
  3. At the end of the installation you will encounter an error that the extension is not supported. Kindly ignore the error and proceed to the next step :)
  4. Restart the computer.
  5. Open Terminal and enter the following commands:
    cd /System/Library/Extensions
    sudo chmod -R 755 RTL8187L.kext
    sudo chown -R 0:0 RTL8187L.kext
    exit
  6. Restart computer once again.
  7. Plug in the Alfa USB wifi device.
  8. Open Terminal and enter the following commands:
    sudo kextutil -t -v 
    /System/Library/Extensions/RTL8187L.kext
    exit
  9. A network window shall pop up where you configure a new profile or connect to an existing wifi hotspot. 
  10. You have now configured your Alfa USB wifi adapter!

Note that each time you reboot the computer, you need to repeat step 8.
