iOS 27 & macOS 27 Betas Hide Clues For Apple’s Foldable iPhone And Touch MacBook

Apple’s annual software betas have a history of revealing more than just new features. Hidden code references and interface changes have often served as early indicators of upcoming hardware. This year is no different. Following the iOS 27 reveal at WWDC, Bloomberg’s Mark Gurman reports that the first developer betas of iOS 27 and macOS 27 contain several references pointing to two long-rumoured products: Apple’s first foldable iPhone and a touchscreen MacBook.

What Do The iOS 27 & macOS 27 Betas Reveal About Apple’s Foldable iPhone?

The clearest clue comes from the iPhone Mirroring app in macOS 27. According to Gurman, the app can now stretch to support much wider layouts, resembling the tablet-like screen format expected when a foldable iPhone is opened. 

Additional references in iOS 27 reportedly include terms such as “foldState”, “angleDegrees”, and support for multiple hardware displays, consistent with a device that needs to detect how far it has been opened or closed.

Apple’s focus on “app adaptability” at WWDC 2026 adds to the picture, with the company encouraging developers to build apps across a wider range of display sizes. Rumours around the so-called iPhone Ultra have also picked up pace, with hardware dummy units said to already be in production. 

Multiple reports suggest a possible debut alongside the iPhone 18 Pros in September, with cheaper models arriving in Spring next year.

How Is macOS 27 Preparing For A Touchscreen MacBook?

The macOS 27 beta carries changes pointing toward a touchscreen MacBook as well. An update to Sidecar reportedly supports broader touch interactions across macOS when paired with an iPad, potentially laying groundwork for a touch-enabled Mac. 

Support for pull-to-refresh gestures has also been added, renewing speculation that Apple is preparing macOS for direct touch input.

Gurman further notes Apple’s redesigned pill-shaped Siri interface on Mac, which he believes could align with a Dynamic Island-style cutout on future MacBook models. Reports suggest OLED MacBook Pro models with touchscreen support could arrive before the end of 2026.
