Apple's upcoming macOS 27 Golden Gate will enhance support for ultrawide displays, allowing for resolutions like 5K at 120Hz. This improvement is particularly significant as it caters to displays with aspect ratios such as 21:9, which have previously been limited to lower resolutions and refresh rates.
Current Mac models, including the M5 MacBook Pro, already provide options for high-end external display configurations, including 5K (5120 x 2880) at 120Hz, depending on the specific model and setup. The functionality available in macOS 27 will ensure that users can maintain their display arrangements seamlessly each time they connect their ultrawide monitors.
While details on the exact native resolutions supported by this new feature remain unspecified, the update is anticipated to be available this fall. In addition to ultrawide display enhancements, macOS 27 Golden Gate will introduce improvements in Liquid Glass, Siri AI, and upgraded Writing Tools.
