Apple is enhancing its macOS 27 with explicit support for ultrawide displays, a feature that enables higher resolution display modes and the preservation of monitor layouts upon reconnection. Announced during WWDC26 on June 8, this update allows Macs to drive higher resolutions on compatible ultrawide displays, with 5K at 120Hz cited as a notable example. Previously, macOS had limited support for ultrawide monitors, but macOS 27 marks the first time this support is highlighted as a standalone feature. Users will benefit from automatic restoration of display arrangements, meaning monitors will return to their previous positions when reconnected, thus reducing setup time. While Apple has not detailed the technical specifications or dependencies of this feature, it is expected to significantly improve the experience for Mac users who frequently connect and disconnect external monitors. The first developer beta of macOS 27 was released on June 8, with a public beta anticipated later this summer and a general release slated for the fall.
