Release notes
What changed
Original editorial synthesis. Linked references appear with the claims they support and in the source ledger.
Archived Apple note state
Internet Archive preserved an Apple Developer raw DocC payload after Beta 1 and before Beta 2. It identifies itself as macOS Tahoe 26 Beta Release Notes and contains 113 structured note items.[1]
Representative Beta 1 inventory
This page structures 10 representative entries across the App Store, Foundation Models, disk images, Metal, networking security, logging privacy, text, StoreKit, TLS, and SwiftUI. It intentionally preserves a balanced set of new APIs, compatibility changes, fixes, and known issues instead of reproducing Apple's full list.[1]
Attribution boundary
This is initial snapshot-state attribution, not a claim that every item debuted at the exact seed publication time. The raw capture precedes Beta 2, so Beta 1 is the only intervening 26.0 milestone; later cumulative material and administrative identity facts are not copied backward.[1]
