Apple macOS Tahoe (26) Update Version macOS Tahoe 26.1

macOS Tahoe 26.1 release notes for the macOS 26.1 SDK, bundled with Xcode 26.1. It includes app fixes, Game Controller improvements, added `sudo` security checks, and a SwiftUI crash fix that requires recompiling against the 26.1 SDK.

• Added security checks when loading /etc/sudoers and /etc/sudoers.d; if the owner is not root, the configuration is ignored and sudo might not work.

• Fixed missing Search bar in the Apple TV app on macOS.
• Fixed AssetPackManager.url(for:) throwing an error for locally available asset files.
• Fixed incorrect time domain returned by GCPressedStateInput.lastPressedStateTimestamp.
• Reduced Game Controller input delays under heavy default global concurrent queue load.
• Fixed non-UI processes not receiving Game Controller input after enabling background event monitoring.
• Fixed navigationLinkIndicatorVisibility crashing on iOS 17, iOS 18, and aligned releases when apps are recompiled against the 26.1 SDK.

• The virtual machine serial number is 0, which prevents iCloud and related applications from functioning correctly.

• The macOS 26.1 SDK is bundled with Xcode 26.1, available from the Mac App Store.
• To receive the SwiftUI fix for navigationLinkIndicatorVisibility, recompile your app against the 26.1 SDK.
• For Xcode 26.1 compatibility requirements, see the Xcode 26.1 release notes.
