Release notes

What changed

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

Sequential archive diff

The CDX-confirmed before and after payloads bracket Beta 2 without crossing another macOS 26 milestone. The after-state page explicitly identifies itself as macOS Tahoe 26 Beta 2 Release Notes.[1][2]

Documented Beta 2 delta

The raw comparison contains 43 added or status-changed lines and 25 removed or superseded lines. This article groups the high-signal issue-ID transitions into 10 copyright-safe editorial occurrences rather than reproducing Apple's changelog.[1][2]

Attribution boundary

Each structured occurrence is limited to an issue ID or status change present in this clean adjacent boundary. A removed note without an explicit replacement is not treated as proof of a fix, and no later Public note or build identity is inherited.[1][2]
