Apple today confirmed that iPadOS 26.3.1 and macOS 26.3.1 are on the way. The updates will likely be released at some point this week or next week.

iPadOS 26.3.1 and macOS 26.3.1 are mentioned on the tech specs page for the new Studio Display and Studio Display XDR, which launch on Wednesday, March 11.

On a related note, both the new Studio Display and the Studio Display XDR are compatible with Apple silicon Macs only, according to Apple. Even then, the Studio Display XDR is limited to 60Hz if you have a Mac with an M1, M1 Pro, M1 Max, M1 Ultra, M2, or M3 chip. The original Studio Display supported some Intel Macs.
