Add a Touch Bar to your old Mac with this free app

The Touch Bar is the tentpole feature of Apple’s newest MacBook Pro models. But it’s a hardware feature, which means it’s something those of us who aren’t going to buy a new computer will have to live without. Until now.

Red Sweater software, maker of MarsEdit and other fine apps for the Mac, has released Touché, an app that simulates the Touch Bar on the screen of any Mac capable of running macOS 10.12 “Sierra.”


The Touch Bar is a touch-sensitive display built into the keyboard on the new MacBook Pro. It replaces the “Function Key” row found on other MacBook models. Because it’s a display, it can be infinitely reconfigured with different buttons and interfaces.

Apple has published tools to help developers support the Touch Bar in their apps.

As you can see in the screenshot, the Touch Bar gives you access to features and functions you’d otherwise have to find using key combinations or clicking on menus. But it’s a lot more than that. Because the Touch Bar is a display, developers can make the interface whatever they want.

Developers working on Touch Bar-enabled apps have access to a Touch Bar simulator. As a development tool, that simulator isn’t something that people who aren’t developing Mac apps have easy access to. So Daniel Jalkut at Red Sweater took the next logical step, releasing Touché (which he’s done on the Red Sweater website). It’s a free app.

Apps that already support the Touch Bar API treat Touché just like a real Touch Bar. So you’ll see the same things in Touché that you’d see on the Touch Bar of a new MacBook Pro. It’s a pretty cool hack. You can make the Touché window go away any time you want if you find that the floating Touch Bar palette is a distraction or blocks your ability to see other stuff on your screen.

Anxious to get started with Touché? One caveat: Touché requires a specific build of macOS 10.12.1 “Sierra” (16B2657, if you’re keeping track). If you’re running an earlier 10.12.1 build, you’ll need to manually download and install this newer build, which is available directly from Apple’s website. There’s a link on the Touché Help page on Red Sweater’s site.

If you’ve never heard of Red Sweater and you’re nervous about downloading software from a site you don’t know, I’ll vouch for them. In fact, this very post was composed using another one of their fine products, MarsEdit, which I am very happy to endorse.
