Significant enhancements could be included in the next major release of Apple's operating system, according to Mark Gurman. In his latest Power On newsletter, Gurman says he expects an update to notifications and an assortment of new health- tracking features.

I'm not expecting an end-to-end redesign of the interface. The extent of interface changes Apple plans for might end with a tweaking of the iPad's multitaskingUI.

Gurman notes watchOS 9 may include improvements to its activity and health tracking features, but stopped short of sharing specifics. It's not clear what Apple has in store for the next version of macOS. The company made its desktop operating system look more like the iPad. Apple introduced features like Universal Control and SharePlay with Monterey.

The new macOS, watchOS 9, and iOS 16 will be shown at the conference. The company's annual developer conference starts on June 6th. Gurman said that Apple is working on new MacBook Air and MacBook Pro models, so it's possible we could see that at the event.
