The Xcode Touch Simulator can view all of software in the computer to show the behavior of touchbar included Safari. You also can use the simulator control of hardware such as reduce display led. You can install lastest update of OSX 10.12.1 (16B2657) and Xcode 8.1 for experiment. I thing it is very good, simple and easy. As not too much animation or movie that made you not force on display. This is designed for a keyboard supplement, not additional display. Touch bar is a point that i may remain in Apple world on next purchase but not enough as a reason that i will buy a new machine because of that. I wish reduce price of touch bar model in the future.
