Q: El Capitan and Lightroom with Topaz Plug Ins

I resented updated my desktop Mac to a new model with El Capitan already loaded. As a photographer I primarily use Lightroom with Topaz Plugs in. I do not use iPhotos as it does not offer the features needed.

Since I obtained the new computer - Lightroom works okay but Topaz no longer works.

I have loaded and removed the program multiple times and have spoken to Topaz via email with no results. They believe it is a licensing issue and provided a patch that does not work. Expensive programs that El Capitan has rendered useless.

Google recently made Nix available and both Topaz or Nik do not seem to be compatible with El Capitan.

Is anyone having any issues?

Solutions?
