Combined with Apple's effort in its mobile ARM-based chipsets across the years, this has prompted speculation that the move away from Intel's x86 architecture will result in Macs eventually running iOS or an iOS-like operating system.
Apple could be planning to ditch Intel and start to manufacture its own chips for Macs by 2020, according to a new report.
It makes sense in Apple-esque fashion that the California tech giant is working on a project of making all its chief devices - including Macs, iPhones and iPads - work off the same microprocessor family. Worse for the chipmaker, the move could spur other PC vendors to control their own processor fabrication by moving it in-house.
It is also a shift fraught with risk for Apple and the company could still theoretically abandon or delay the switch, the report notes. The company's A-series of processors, now capped by the A11 Bionic chips used in the iPhones 8, 8 Plus and X, are all designed by the company for specific purposes, and based on an architecture licensed from British firm ARM.
Transitioning to proprietary chips would free Apple from the constraints of Intel's production roadmap and allow it to be more flexible with time frames. Though it could also just mean Apple is experimenting with different kinds of prototypes while it readies its new generation of computers.
China, US Inch Closer to Trade War; Farmers Caught in Middle
The measures announced Sunday matched a list of potential tariffs on up to $3 billion in USA goods published by China on March 23. Trump's tariffs are partly a response to complaints that Beijing steals or pressures foreign companies to hand over technology.
According to The Verge, the changeover is expected to begin with Apple's less power-intensive computers, such as the 12ins MacBook. Dell Technologies Inc., HP Inc., Lenovo Group Ltd., and Asustek Computer Inc. use Intel chips. Intel also said that the company does not comment on rumors about its customers. It more than tripled in 2016 and doubled again a year ago.
This could prove to be a big blow for Intel as they are the biggest providers for chips for Mac.
Apple sold over 19m Macs last year, with the top-of-the-line computers accounting for 11pc of the company's $229.2bn revenue last year.
In 2005, Apple announced a move to Intel chips in its Macs, an initiative that put former Intel Chief Executive Officer Paul Ottelini on stage with Apple co-founder Steve Jobs.
Which is to say don't hold your breath for Apple AR glasses or a microLED-powered iMac. Furthermore, a custom chip design will bring better performance and battery efficiency to the future MacBooks, something Windows competitors depending on Intel chips are still struggling to implement.
