Mac Moving To ARM?

There’s a fresh rumor about Apple selling Macs that use custom ARM CPUs instead of Intel silicon as early as 2020. I wrote a breezy 1600 words about it for Fast Company.

Here are some highlights, to entice you to read the whole thing:

  • I like this rumor a lot. Apple making custom CPUs for Macs makes perfect sense.
  • The timing is interesting, too. WWDC is two months away. If Apple has committed to this kind of move and planned to announce it on June 4, they would have recently expanded the group of “people who need to know” to include “possible blabbermouths.”
  • I don’t think Apple would drop Intel completely. It’s easier for me to imagine them using custom CPUs for their consumer-grade Macs and sticking with Intel for the high-horsepower Pro desktops and notebooks. At least for starters.
  • Remember that iOS and MacOS are built on the same foundation. During my very first briefing on the iPhone, Apple told me that the iPhone’s OS is OS X with none of the stuff the Mac needs and all of the things a phone needs.
  • ARM is such a huge move — and presents such a big opportunity for change — that I would expect it to accompany a whole new historical age for the Mac. Either Apple would do radical (and long-overdue) modern rethink, akin to what Microsoft did with Windows 10…or they would effectively transform MacOS into an enhanced version of iOS, in function if not in name.

As much as I like this rumor, I’m still cautious. Apple tries lots of ideas and builds lots of ready-for-market hardware before they commit to anything big. I’ve no doubts whatsoever that there are a whole bunch of ARM-based Mac laptops inside the Apple campus, and that an ARM version of MacOS is done and dusted and has been for some time. But even if someone leaked Apple’s entire WWDC keynote slide deck to me a week before, I refuse to believe any rumor until Apple formally announces.
