PROBLEM SOLVED!!
What you need to do is to enable kernel extensions on your mac!
Just make sure that you have the latest drivers downloaded, then follow these steps:
Go to system preferences - security & privacy - general. Then under "allow apps downloaded from" you should see a box where it says "enable system extensions". Click on the locker in the bottom left corner, then click "enable system extensions". Then follow the steps in this video:

Good luck!
