Overview
- The updates prepare iPhone, iPad, and Mac for Studio Display 2 and Studio Display XDR, which go on sale March 11.
- macOS 26.3.1 enables the new displays on compatible Apple silicon Macs, with Intel-based models not supported.
- Apple published no security fixes or CVE entries for version 26.3.1 across iOS, iPadOS, or macOS.
- Separately, Apple released iOS 18.7.6 for iPhone XR and XS to fix problems reaching emergency numbers in Australia.
- Guidance from coverage indicates the updates are urgent mainly for buyers of the new monitors, so others can delay installation.
