Apple’s decision to bring touchscreen support to the new OLED-equipped MacBook Pro meant it had to also change macOS to work with it. However, the alterations won’t be limited to just Apple’s latest notebook launch at all.
Anyone using a touch-enabled external display will also be able to benefit from the new interface in macOS 27. That includes anyone that uses Sidecar with an iPad.
