With the new MacBooks Apple introduced Touch Bar. Fine for the few who will purchase a new MacBook but what about the rest of us? One could guess we have to wait for new iMacs or Mac Pros to appear in the spring with Touch Bar. Maybe then an external keyboard could be had to work with older Macs. Enter Duet Display. You run half on your Mac or PC and the other half on your iPad. It gives you a dual display environment. But if you are running a Mac and you call up an app with Touch Bar support....like Pages.....the iPad does the Touch Bar at the bottom of its screen. So we do have an interim solution for doing Touch Bar with Photoshop, Pixelmater, and other apps. We don't have to save $3,000+ for a new MacBook if we want Touch Bar. And that also means we need the post processing app vendors to step up and do Touch Bar. Example....Adobe needs to do Touch Bar in Lightroom.
