I was able to get it working again on my mac. Following the directions here 
(http://joshuawise.com/horndis also copied below) to uninstall HoRNDIS then 
reinstalling it got everything working again. Just trying to reinstall did 
not work.

***Uninstalling HoRNDIS on a mac***

If, for some reason, you need to uninstall HoRNDIS, you can simply drag the 
extension to the trash. In the Finder, go to the “Go” menu, and select “Go 
to folder...”; in that, type ”/System/Library/Extensions”. Find 
“HoRNDIS.kext”, and drag it to the trash. When prompted, type your 
password; then, restart your Mac to be sure it is unloaded.
