Almost every iOS Messages feature is now on the Mac too, even Memoji!

Look Around and Favorites in Maps are on macOS too!

The Mac is transitioning to Apple's custom silicon!

Apple silicon brings the Mac to much better performance with less power consumption.

All Mac apps are now native and Xcode will support Apple Silicon, so all your favorite apps will support AS Macs as well as Intel Macs.

Apple are already running Big Sur on A12Z Bionic, the CPU used in iPad Pro.

Rosetta 2 will allow you to run apps for Intel Macs on AS Macs from day one, and it's much faster. And there are new virtualization features too.

The first AS Mac will be released by the end of the year, while developers can start transitioning now.

WWDC has ended.
