As usual with such stories, the details are sourced to “people familiar with the plans” and Apple has declined comment. But I give this rumor a lot of credibility. Any such move would require the company to bring Mac developers into the loop as early as possible, so they can prepare their apps. If Apple is planning to do that at this year’s Worldwide Developers Conference (which opens on June 4), then we’re now within that window of time where I would expect the pool of people who have access to that information to have expanded to include possible blabbermouths.

More than that, however, the move emphatically makes sense. Apple’s consumer desktop strategy since the introduction of the iPad has sounded out as clearly as the first five notes of “Shave And A Haircut” and at this point, the response “TWO BITS!”–in the form of an ARM-based Mac–seems inevitable. It’s compatible with so many of Apple’s goals and frustrations.

Faster and better Macs come along at a glacial pace, a fact that Apple can’t wholly blame on Intel. But Apple’s dependency on Intel’s CPU roadmap and release dates isn’t helpful. And Apple has a holistic approach to hardware design that has paid off well for both Apple and its users. Practically every major component inside an iOS device has been purpose-built to enhance the performance and the role of every other component, and the same goes for the relationship between the operating system itself and the overall hardware. The iPad Pro–which is every bit as powerful as almost any consumer-grade laptop–soars thanks to a level of design intimacy between…
