B&W Effects - Issues after Mac OS & CC Updates

Recently (after the most recent Mac OS & Photoshop updates) my Topaz Black & White Effects has started running super slow. I have tried reinstalling the plugin, and searching online for answers, but have not yest been able to solve the issue. Just wondering if anyone might know something that I don’t.
Thanks
