Overview
- Apple made macOS Tahoe 26.2 public beta 2 available to testers, matching the developer beta 2 build and highlighting the new Edge Light effect.
- Edge Light creates an adjustable glow around the screen’s perimeter to mimic a ring light, with controls for thickness and color temperature.
- The effect leverages the Neural Engine and the Image Signal Processor for face detection and environment‑aware brightness, recedes near the pointer, and does not appear in screenshots.
- Support spans all Apple silicon Macs and works with FaceTime, Zoom, Teams, Meet, and WebEx, plus Studio Display and external cameras, with optional auto‑enable in low light on 2024‑and‑newer models.
- Early tests report noticeable improvements in very dim rooms but modest gains in brighter setups, and a broader public release is expected in December if the schedule holds.
