What it also means for Mac users is that in order to deal with the current lack of compatible and optimized apps for the M1 chipset, macOS Big Sur will also be capable of running iPhone and iPad apps, where users will be able to download these apps from the App Store. Apps designed for the iPhone and iPad will be available for macOS Big Sur by default, but as previously reported, developers do have the option of opting out of it.
Apple has cautioned users that while iPhone and iPad apps will be available on Big Sur, not all of them might necessarily work as intended. “Some apps available on Mac may not function as they normally would on iPhone or iPad. For example, features that rely on hardware unique to iPhone or iPad—such as a gyroscope or a screen that supports complex Multi-Touch gestures—may not work on Mac. In some cases such a feature may be central to the app’s functionality, while in others the app may be usable without it.”
We imagine that this is a temporary thing as it is possible that Apple is hoping that developers will eventually create apps with macOS, iOS, and iPadOS and bundle them together. While the experience might not necessarily be ideal or optimal, it will have to do for now.
