Apple has called an event under the name "Pro and tell", and as Golem reports, a MacBook Pro with a touchscreen could be unveiled there. If that holds, it is not product maintenance — it is a reversal. Apple spent more than a decade calling touch on the Mac the wrong idea.

The arguments against it were always the same. Steve Jobs called touch laptops an ergonomic mistake; Craig Federighi later said Apple had built prototypes and shelved them because holding an arm up to a vertical display tires the shoulder. The company's answer was the iPad Pro instead — keyboard, pencil, and software that has crept steadily toward the desktop.

A touchscreen Mac scrambles that arrangement. If macOS machines accept fingers, the software has to follow: larger hit targets, a different relationship with cursors and windows, and presumably stylus support that does not feel bolted on. Fitting a panel is easy. Changing an interaction model that has rested on pointing devices since 1984 is not.

The second open question is the iPad. A touch-and-pencil MacBook Pro overlaps with the most expensive iPad Pro setup, and Apple has traditionally been careful about letting its own products collide. The escape route is a clean split: iPad for direct manipulation, Mac for keyboard work where touch is an addition rather than a replacement.

For calibration: touchscreen Macs have been rumoured for years, usually with OLED panels and a timeline that kept slipping. An invite called "Pro and tell" plainly points at pro hardware; it does not guarantee a touch MacBook follows. Until the keynote, this is a report about an expectation, not a product.

What to watch: whether Apple opens touch across macOS or confines it to a few apps, whether the Apple Pencil comes along, and at what price. A touchscreen that only moves windows around would be the most expensive way ever devised to change nothing.
