Here’s how macOS is changing for touchscreens

The more interesting stuff will probably happen in individual apps. Unsurprisingly, Apple’s apps will already be “optimized” for touch, and the system will automatically translate touches into clicks. Apart from that, Apple lists a handful of third-party apps that will take advantage of the new touch controls, including Notion, Canva, Zoom, Word, Excel, PowerPoint, Lightroom, and DaVinci Resolve. Adding the possibility of multitouch to some of these pro creator apps is interesting, but for the most part it seems that touch will merely be a secondary input mechanism rather than a whole new way of interacting with the entire system.
