So, I contacted the administrator known as Line6Tony about the new OS X driver and received the following response on the 8th of October: Hello Jordan. I apologize for the trouble you and other customers run into regarding our driver. Unfortunately, we do not have a firm date for a release, as there are many variables in play when resolving software issues. Please know that it is a high priority within the company, as we realize many of our customers are now using El Capitan as their OS.
So basically, they're still working on it and it's not close to being finished.
