References to the TrueDepth camera found in macOS Big Sur beta 3 suggest Apple is working on bringing Face ID to Macs
let me dream — how about Big Sur is being tested on the iPad Pro https://9to5mac.com/...
Context & Ripple Effects
Face ID on the Mac has a long paper trail before today's find: back in 2017, Bloomberg sources reported Apple testing a 3D facial-recognition sensor for unlocking and payments, and in 2019 Apple quietly trialed biometric sign-in for iCloud.com across iOS and macOS betas. The TrueDepth strings in Big Sur beta 3 are the first time that work appears aimed specifically at Mac hardware rather than web sign-in.
The timing also fits a broader sensor story: iOS 13 builds referenced stereo AR headsets and apps, and by 2024-2025 Apple had shipped visionOS 2's ultra-wide Mac Virtual Display and was reported working on a Mac-tethered Vision Pro model. Shared depth-sensing silicon across Mac, iPhone, and a face-mounted device is the common thread.
First-order effects
- If TrueDepth lands in Macs, Apple gains a unified biometric unlock across its lineup, replacing password entry at login and extending the TrueDepth module supply chain beyond iPhone and iPad.
Second-order effects
- A Mac-facing TrueDepth camera gives Apple's spatial platform a second anchor point: a tethered Vision Pro model could lean on the Mac's depth sensors rather than duplicating them, tightening the Mac-headset pairing.
Third-order effects
- The multi-year cadence — 2017 sensor testing, 2019 iCloud biometrics and AR headset references, 2020 beta code — suggests Apple seeds next-hardware features in OS betas well before products ship, making beta string-mining a leading indicator of its hardware roadmap.
The trend: Apple is converging biometric and depth-sensing hardware across iPhone, Mac, and its spatial computing line, with each OS beta revealing another layer of that shared architecture.
