iOS 27 and macOS 27 betas hint at folding iPhone, MacBook

The first developer betas of Apple's upcoming iOS 27 and macOS 27 operating systems contain multiple software clues pointing to the company's long-rumored development of a folding iPhone and a touchscreen MacBook. While Apple has not officially announced either product, code references and interface changes discovered in the early software builds suggest active preparation for new hardware form factors.

Within the iOS 27 beta, developers have found system code referencing variables such as "foldState" and "angleDegrees," parameters that would be necessary for a device that can physically fold. The code also includes identifiers for multiple displays. These elements strongly indicate that Apple is engineering software support for a folding iPhone, which has been widely referred to in rumors as the iPhone Ultra or iPhone Fold.

Further evidence comes from updates to the iPhone Mirroring feature in macOS 27. Previously limited to a few fixed window sizes, the tool now allows for a freely resizable window. When stretched to wider, iPad-like dimensions, many of Apple's own built-in applications dynamically adapt their layouts. This push for "app adaptability," a concept Apple...
