Apple's emphasis on security makes ARM-powered Macs 'inevitable'

Apple convinces analyst that Macs will eventually run on custom silicon, not Intel's processors

But if security is at root a critical component of Apple's strategy, Bajarin argued, it surely must expand from the iOS platform to the Mac. That's where ARM, the processor architecture that Apple's SoCs are based upon, comes in.

"OS X has its own security story," Bajarin acknowledged. "But given the narrative Apple's trying to tell and how much time they've spent on this philosophy, if they're serious about security they need to bring it to every bit of their product line."

To accomplish on the Mac what it's done on the iPhone, Apple would have to abandon Intel as its processor supplier, and use its own A-series SoC and Secure Enclave. In turn, that would mean OS X would be discarded, at least for those Macs equipped with ARM-based silicon, and replaced by iOS itself or a variation of the operating system.

Apple's emphasis on security and encryption, and how they are implemented in the iPhone by Apple's customization strategy, said Bajarin, made it clear: "It signals that it's inevitable that they will do the same for all the products that they can," he concluded.

Bajarin published an initial analysis of Apple's security strategy Monday; unlike Tuesday's piece, the first can be read free of charge.
