Apple has today released iOS 18.1.1, iPadOS 18.1.1, and macOS Sequoia 15.1.1, addressing several security vulnerabilities, including some that Apple believes may have been actively exploited.
As iOS 18.1.1, iPadOS 18.1.1, and macOS Sequoia 15.1.1 were not distributed to external testers prior to their release, we do not have any information on whether they contain any accessibility fixes for blind, def blind, or low vision users at the time of writing. However, as these updates appear to have been released to address a small number of specific issues, we do not expect them to contain any such fixes.
Release notes
Apple's release notes for iOS 18.1.1, iPadOS 18.1.1, and macOS Sequoia 15.1.1 simply state that the updates "Provide important security fixes."
How to update
iOS 18.1.1 and iPadOS 18.1.1 are available via Over-the-Air Update (Settings > General > Software Update) via Finder on a Mac with macOS Catalina or later, or via iTunes on a PC or Mac with macOS Mojave or earlier.
To install macOS Sequoia 15.1.1, choose System Settings from the Apple menu, select General in the table, click Software Update in the scroll area, and click the Update Now button to begin the update process. If other updates are available, you can click "More info" to see details about them and select specific updates to install.
