The Touch Bar Demo App is essentially a hack that brings the TouchBar to older Macs with the help of an iPad. Since iPad has a touchscreen, one can experience the closest to the actual Touch Bar. The bar will also dynamically change depending on the applications you have opened, and it works on any Mac running the latest macOS or even the iMac and the Mac Pros. In order to get going with the TouchBar, ensure that your MacBook is running the latest macOS Sierra build, version 10.12.1. 16B2657, which natively supports the touch bar. Now all you need to do is head over to the Touch Bar Demo App’s GitHub Page and download the application, yes it is that simple no unnecessary fiddling around. Moving on, installing the app on the iPad is slightly complicated as the OS doesn’t support the Touch Bar natively. In order to get the feature, you need to have Xcode installed and then download the ToucBar Xcode project file from the GitHub repo and sideload the application. Once installed, launch the application, and Voila! Your iPad now has the TouchBar up and running. The last step involves setting up the display to work with the iPad via USB.
