Overview
- Edge Light illuminates the screen borders to mimic a ring light and recedes near the cursor so on‑screen content remains usable.
- The feature is available on Apple silicon Macs running macOS 26.2, with automatic low‑light activation limited to models introduced in 2024 or later.
- Users enable Edge Light from the menu bar’s Video controls during a call, where sliders adjust brightness and color temperature and an auto‑enable option can be set.
- With the built‑in camera, the effect appears on the built‑in display; when using Continuity Camera or an external camera across multiple displays, it shows on the primary display and can be combined with other video effects.
- Developer Gui Rambo released LightBuddy for $4.99, adding HDR lighting, full color selection and per‑display settings, and it runs on Intel Macs with macOS 14 or later.
