Release notes

What changed

Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.

Release identity

This article enriches the existing macOS 26.1 Beta 1 route dated 2025-09-22. It does not alter the audited timeline date or create a second event.[1]

Archived Apple note state

Internet Archive retained Apple's human documentation shell and its structured DocC payload during the interval after Beta 1 and before Beta 2. The raw document identifies itself as the macOS 26.1 beta notes and contains 5 itemized entries represented here.[2]

Documented initial inventory

The preserved state covers the Apple TV app, Background Assets, Game Controller, sudo configuration ownership, and SwiftUI compatibility. Resolved issues, new capabilities, API changes, and known issues remain separately labeled in the structured inventory.[2]

Attribution boundary

This is direct initial-snapshot evidence, not a claim that every item appeared at the exact release hour. The raw capture falls before Beta 2, so no later milestone is crossed and no final cumulative note is copied backward.[2]
