Apple:

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.

There it is. The biggest day in Apple history in the past 10 years. It’s going to be fascinating.
