A New Kind of Ring Light

When you think of a ring light, you probably picture a small, battery‑powered LED halo that you clip onto your webcam. Apple’s Edge Light flips that image on its head: the Mac’s own display becomes the light source, illuminating your face from the inside out. The feature, announced in the second MacOS 26.2 developer beta, is designed for the growing number of professionals who rely on FaceTime and other video‑call apps from their laptops.

“Edge Light is a camera effect that uses your Mac’s display to omit a bright white border around the screen, aiming to enhance your picture and appearance in low‑light conditions,” ZDNET reports.

The idea is simple—use the screen’s brightness to fill in shadows around the user’s face. But the implementation is anything but trivial.

How Edge Light Works Under the Hood

Apple leverages its Neural Engine to detect the user’s face, size, and position in real time. Once the system identifies the target area, it dynamically adjusts the brightness and hue of the surrounding pixels to create a halo effect. The result is a subtle, natural‑looking illumination that feels like a ring light without the extra hardware.

Edge Light is available alongside other FaceTime enhancements such as Portrait Mode, Studio Light, and Voice Isolation. It supports both the built‑in FaceTime camera and external webcams, provided the Mac runs Apple Silicon (M1 or newer). The beta version is currently limited to developers; the public release is slated for December.

What Developers Need to Know

For developers, Edge Light presents a new API surface to consider when building video‑call or AR experiences. While the public SDK documentation is still sparse, early beta builds indicate that the feature can be toggled via the Camera settings in the system preferences.

# Enable Developer Mode (required for the beta)
sudo softwareupdate --install-rosetta
sudo softwareupdate --install --agree-to-license

“Developer betas can be unstable, so refrain from downloading them to your personal device,” advises ZDNET. Backing up your data before installing the beta is strongly recommended.

The feature’s reliance on the Neural Engine also means that older Macs (pre‑M1) will not see any benefit, narrowing the target audience to the modern Apple Silicon lineup.

Trying Edge Light on Your Mac

  1. Enroll in Apple’s Developer Program or Beta Software Program.
  2. Back up your machine.
  3. Go to Settings > General > Software Updates > Beta Updates and download the 26.2 beta.
  4. If you’re a developer, enable Developer Mode before installing.
  5. Once installed, open FaceTime and look for the Edge Light toggle in the camera settings.

If you’re curious but not ready to risk a beta, keep an eye on the public release in December.

Why It Matters

Edge Light reflects a broader trend: software‑defined hardware. By turning the display into a light source, Apple eliminates the need for external peripherals, streamlining the video‑call experience. For remote workers, this could reduce the clutter on desks and lower the cost of professional‑grade video setups.

From a developer standpoint, the feature opens new possibilities for UI designers to create immersive, context‑aware interfaces that adapt to a user’s lighting conditions without external sensors.

The Bottom Line

Apple’s Edge Light is a clever, low‑maintenance solution to a perennial problem in virtual meetings. While the beta’s stability remains to be proven, the concept signals a shift toward more integrated, software‑centric solutions in the Mac ecosystem.

For now, developers can experiment with the feature in the 26.2 beta, but users should wait for the public release to avoid potential bugs and data loss.
