When Bloomberg reported that Apple is planning to ditch Intel and design its own chips for Macs as early as 2020 many industry pundits and users were left wondering if this was a good thing or not.
Architosh’s first story on the news questions if the pro app markets, like industrial CAD systems in AEC and manufacturing, will cope well with such a transition.
Of course, the question of using the ARM-architecture (which Apple designs its A-series CPUs around for iOS devices) for future Macs has been raised before. Many times, in fact. (see: Architosh, “More Apple Mac ARM Rumors—This Time MacBook Air,” 11 May 2011; and Architosh, “Editorial: ARM-based Macs are a bad idea for Apple’s growing Mac professional base,” 15 Jan 2015)
Building A Secure Enclave
“It was only a matter of time before Apple made the move to put their own processors on their desktops,” says Paul Norris, senior systems engineer for EMEA at cybersecurity firm Tripwire. Norris argues not only has Apple been successfully designing central processing units (CPUs) for their iOS devices for years, but by doing so they offer “a secure enclave between operating system and hardware.”
This move is likely about hardening security on Apple platforms and across their ecosystems. With spectacular security failures highlighting the ultimate vulnerabilities of end users and their private data—from the famed Sony hack to the stealing of Hillary Rodham Clinton’s emails to the story of Cambridge Analytica—there is no better time for Apple to take a stance on hardened security.
Intel Has Disadvantages
When it comes to security issues, Intel has built-in disadvantages to Apple in a CPU arms race. “Apple is taking advantage of the relationship between operating system and hardware of their OS X based devices to guarantee strengthened security,” says Norris. “Intel has to cater to a number of different types of operating systems and hardware devices, which increases the likelihood a vulnerability is identified.”

Norris makes the point in a private communication to Architosh that Apple has tremendous depth, expertise, and years of experience developing CPUs. “As Apple is not new to developing microprocessors, consumers should welcome this news.”
Security Ain’t Everything, Or Is It?
For the longest time, Moore’s Law has taught us that performance (processing speed) was the chief metric for evaluating chips. The faster the chip, the faster you can get your work done. Moore’s Law assured us that chips would continue to shrink in manufacturing process size and thus transistor counts would dramatically grow increasing performance over time. Moore’s Law, however, has hit a wall in recent times as smaller process size stretches the limits of manufacturing.
And performance is changing in the face of other advances in computer technology. The cloud with mobile devices is changing the market to think about splitting the work between cloud-compute and edge-compute. Some things (usually involving large data sets) are better computed in the cloud, while other things, like AI, require faster immediate results and are better computed on your mobile device out on the edge. Your iPhone X’s face recognition is one such example of the latter.
Devices as Gateways to Data
Today’s devices are gateways to large data living in the cloud. It is imperative that security become strengthened. Apple’s Mac computers have a possible future of being both edge-compute devices and cloud compute devices. ARM chips are already ideal for the data center, and future ARM-based Macs may find their way back into the data center, including Apple’s.
There is every chance that Apple stands a chance at taking on the major players in the CPU market.
This news may signal that Apple intends its new Mac Pro to be “modular” not just to please 3D visualization and film professionals with a machine with tons of customization, but instead be modular to enable it to fit into racks in data centers. The new modular Mac Pro may be modular from its outside shape and ultimate reconfigurability.
Customizing a Chip Around macOS
Paul Norris doesn’t know if Apple’s new processors for Macs will be backward compatible with Intel x86 architecture but instead says its too early to speculate. This is the issue that Architosh readers are very concerned with—that pro application stack compatibility. People live and die by applications, not just by security around their data.
Still, Norris doesn’t think folks should worry so much. “Apple has a good track record of ensuring that when they introduce a new platform, product or process, they invest a lot of money in research and development to ensure there is a seamless integration.”
As for performance, future Apple CPU Macs may be faster. “There is every chance that Apple stands a chance at taking on the major players in the CPU market,” says Norris. “Intel and AMD have a huge market share, but there is always room to welcome new competitors to this space,” he adds, “especially a competitor who has a large user base and a good track record for being secure. Maybe it’s time for a change in this market?”
