Update Summary

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.

Update Details

Security

  • 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.

Bug Fixes

  • 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.

Known Issues

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

Hints

  • 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.
