Apple’s security index now lists iOS/iPadOS 26.7, macOS Sequoia 15.8, and macOS Tahoe 26.7 — companion security builds for anyone not jumping to OS 27 yet.
Alongside the OS 27 public launch, Apple is also shipping companion maintenance updates for people staying on last year’s trains. Apple’s own security releases index now lists them for September 14, 2026 — the gate that earlier outlet-only reports could not clear on their own.
Apple’s security catalog and outlet build notes (AppleInsider, MacRumors, 9to5Mac) agree on:
| Update | Build |
|---|---|
| iOS 26.7 / iPadOS 26.7 | 23H24 |
| macOS Sequoia 15.8 | 24H23 |
| macOS Tahoe 26.7 | 25G229 |
Apple’s index links a dedicated advisory for iOS 26.7 and iPadOS 26.7. MacRumors separately reports that iOS 26.7 carries a large security slate (including many of the same fixes as iOS 27) for users who are not jumping to the new major release yet (MacRumors security rundown).
These are not feature trains. Expect important security / bug-fix packaging without Siri AI and the rest of the OS 27 headline set.
If you already moved to OS 27, you do not need these companion builds.
Yesterday’s prior hold was correct while Apple’s public security index still topped out at 26.6.2. That page now includes 26.7 / 15.8 / Tahoe 26.7, so the companion path is Apple-confirmed for readers postponing iOS 27 / macOS 27.
