One addition to macOS 27 Golden Gate that went unmentioned during yesterday’s WWDC keynote was the fact that the system has improved its ultrawide display support. Here are the details.

macOS 27 expands ultrawide display support

According to Apple, macOS 27 Golden Gate lets owners of ultrawide displays get higher resolutions, such as 5K at 120Hz.

Currently, several Macs already support high-end external display modes such as 5K at 120Hz. The M5 MacBook Pro, for instance, can drive external displays in several configurations and at different native resolutions, including 5K (5120 x 2880) at 120Hz, depending on the model and setup.

In other words, Apple’s documented 5K at 120Hz support refers to a standard 16:9 resolution, with the number of external monitors depending on the chip, whether it is an M5, M5 Pro, or M5 Max.
