macOS Tahoe 26.3.1 Update Released with Support for New Studio Displays
Apple has released macOS Tahoe 26.3.1 with support for the newly updated Apple Studio Display and Studio Display XDR. The update also apparently includes bug fixes, though none are specified in release notes. No security patches are included in this update.
Unless you plan on getting one of the new Apple Studio Displays for your Mac in the near future, these updates are probably not super urgent to install for most Tahoe users, especially given there’s no specificity to which bugs are addressed. Keep in mind that macOS Tahoe 26.4 is under active development, and will likely be released this month to all users as well.
Separately, Apple also released iOS 26.3.1, iPadOS 26.3.1, iOS 18.7.6, and visionOS 26.3.1, all also with support for the new 27″ Studio Display from Apple.
