It works in Yosemite but there is an issue that is heavily taxing the CPU. Have you noticed this on your system? With PT and 003 running, open Activity Monitor and under CPU look for the item called "kernel_task". It should normally be between 3-5% but a lot of us are seeing 85-110%! I'm really hoping an updated driver and El Capitan will fix this.
