All the rumors we've heard over the past couple of years about Apple switching completely to ARM were true. At today's WWDC 2020 event, the Cupertino-based company announced the start of a two-year transition to ARM. The company will sell a developer kit to software makers and will ship its first ARM-based Mac computers before the end of this year.

The company focused primarily on the transition itself, it's still unknown whether the first ARM-based Mac will be a laptop or a desktop computer. CEO Tim Cook said that the company will still introduce new Intel-based versions of its Macs, but within the next two years every model will have an ARM-based variant. Starting with the release of MacOS 11 Big Sur, Apple will offer support for both ARM and x86 hardware.

Apple has already developed ARM-based versions of all of its software, including professional software like Final Cut Pro and Logic Pro. The firm is cooperating with Microsoft and Adobe to make Office and Creative Cloud compatible with the ARM-based Macs, and there will be Rosetta 2 emulation to run x86 software on ARM-based Macs. A couple of demos were given and software like Maya and games like Shadow of the Tomb Raider seemed to run decently on the ARM-based test platform, which used an Apple A12Z SoC.

Apple claims the switch to inhouse ARM chips will result in "industry-leading performance per watt and higher performance GPUs." It will bring all Apple products to the same platform and will enable Apple to come up with its own features and technology. It also further reduces reliance on third parties. With all the problems Intel has with its 10nm node, Apple is probably glad they set up this project years ago as they can now make their own roadmap.

Apple MacBook Pro with MacOS 11
In a historic day for the Mac, Apple today announced it will transition the Mac to its world-class custom silicon to deliver industry-leading performance and powerful new technologies. Developers can now get started updating their apps to take advantage of the advanced capabilities of Apple silicon in the Mac. This transition will also establish a common architecture across all Apple products, making it far easier for developers to write and optimize their apps for the entire ecosystem.

Apple today also introduced macOS Big Sur, the next major release of macOS, which delivers its biggest update in more than a decade and includes technologies that will ensure a smooth and seamless transition to Apple silicon. Developers can easily convert their existing apps to run on Apple silicon, taking advantage of its powerful technologies and performance. And for the first time, developers can make their iOS and iPadOS apps available on the Mac without any modifications.

To help developers get started with Apple silicon, Apple is also launching the Universal App Quick Start Program, which provides access to documentation, forums support, beta versions of macOS Big Sur and Xcode 12, and the limited use of a Developer Transition Kit (DTK), a Mac development system based on Apple’s A12Z Bionic System on a Chip (SoC).

Apple plans to ship the first Mac with Apple silicon by the end of the year and complete the transition in about two years. Apple will continue to support and release new versions of macOS for Intel-based Macs for years to come, and has exciting new Intel-based Macs in development. The transition to Apple silicon represents the biggest leap ever for the Mac.

“From the beginning, the Mac has always embraced big changes to stay at the forefront of personal computing. Today we’re announcing our transition to Apple silicon, making this a historic day for the Mac,” said Tim Cook, Apple’s CEO. “With its powerful features and industry-leading performance, Apple silicon will make the Mac stronger and more capable than ever. I’ve never been more excited about the future of the Mac.”

Family of Mac SoCs to Deliver Powerful New Features and Best-in-Class Performance
For over a decade, Apple’s world-class silicon design team has been building and refining Apple SoCs. The result is a scalable architecture custom designed for iPhone, iPad, and Apple Watch that leads the industry in unique features and performance per watt, and makes each of them best in class. Building upon this architecture, Apple is designing a family of SoCs for the Mac. This will give the Mac industry-leading performance per watt and higher performance GPUs — enabling app developers to write even more powerful pro apps and high-end games. And access to technologies such as the Neural Engine will make the Mac an amazing platform for developers to use machine learning. This will also create a common architecture across all Apple products, making it far easier for developers to write and optimize software for the entire Apple ecosystem.

macOS Big Sur Enables Transition to Apple Silicon
In macOS Big Sur, Apple is offering a range of technologies to make the transition to Apple silicon smooth and seamless. With everything built into Xcode 12, such as native compilers, editors, and debugging tools, most developers will be able to get their apps running in a matter of days. Using Universal 2 application binaries, developers will be able to easily create a single app that taps into the native power and performance of the new Macs with Apple silicon, while still supporting Intel-based Macs. With the translation technology of Rosetta 2, users will be able to run existing Mac apps that have not yet been updated, including those with plug-ins. Virtualization technology allows users to run Linux. Developers can also make their iOS and iPadOS apps available on the Mac without any modifications.

Quick Start Program Lets Developers Get Started Today
Apple Developer Program members can start moving their apps to Apple silicon today by applying for the Universal App Quick Start Program. The program provides access to documentation, forums support, beta versions of macOS Big Sur and Xcode 12, and includes the limited use of a DTK, which will enable developers to build and test their Universal 2 apps. The DTK, which must be returned to Apple at the end of the program, consists of a Mac mini with Apple’s A12Z Bionic SoC inside and desktop specs, including 16GB of memory, a 512GB SSD, and a variety of Mac I/O ports. Developers can apply to the program at developer.apple.com, and the total cost of the program is $500.
