The generic USB Ethernet Adapter equivalent to Apple’s pricey £25 option is called the RD9700. Since it’s generic, and made in China – the support you are likely to receive after purchasing it for a few quid on eBay or Amazon is going to be below your expectations.

Unless you’re a pro user, it is likely Apple’s restrictions on USB-to-Ethernet adapters on the Mac will make using your RD9700 difficult. Fear not, we have a solution. Though it’s a little long it has been tested and confirmed working on all flavours of OS X from 10.4 onwards!

How to install drivers for the RD9700 on Mac OS X

You’ll need to start by uninstalling any drivers you have previously installed. Depending on what you’ve tried – this will vary from user to use – so please to make sure you uninstall and earlier drivers that may conflict with this tutorial.

Step 9: Reboot again.

Step 10: Now plug-in your USB Ethernet Adapter with a live ethernet cable. Open System Preferences and go to Network.

Step 11: Press the + button in the bottom right and select USB 2.0 10/100M Ethernet Adapter and then click Add.

Step 12: Disconnect from WiFi and you should notice your network connect still works through the RD9700 Ethernet Adapter. In addition, you will be able to share internet using the RD9700 too.
