To recall, Apple had confirmed ARM-based Macs at WWDC back in June but said the transition will take around two years. Apple is said to be letting developers run their software on Mac powered by the iPad Pro processor to see how this might affect its software ecosystem. The ARM-based Macs should have the ability to run iOS software designed for iPhone and iPad on Mac computers. This should be enabled by the upcoming macOS Big Sur update (expected to roll out after the launch event) and will bridge the gap with iOS, iPadOS, and macOS.
Besides Apple MacBooks, we can speculate the Cupertino giant may introduce Apple AirTags and Apple AirPods Studio headphones on the stage. However, details about the same are a mystery for now.
