Apple has released macOS 26.3.1, a software update that adds support for the new Studio Display and Studio Display XDR models. The update arrives alongside the launch of the MacBook Neo and other M5-powered MacBooks, ensuring compatibility with Apple's latest hardware lineup.

This minor update expands external display support to include the 2026 Studio Display models, which were unveiled yesterday. Apple's release notes specifically mention bug fixes alongside the display compatibility improvements, suggesting this is primarily a maintenance release rather than a feature-packed update.

macOS 26.3.1 is expected to ship pre-installed on all new MacBooks introduced this week, including the MacBook Neo, M5 MacBook Air, and MacBook Pro with M5 Pro and M5 Max chips. The timing aligns perfectly with today's pre-order availability for these new devices and the Studio Display lineup, making this update essential for users planning to upgrade their Mac hardware.
