See how well macOS 26.2 Tahoe’s new ‘Edge Light’ works in the dark

Apple this week released the second beta version of macOS Tahoe 26.2 for developers. While the update isn’t exactly big, it does come with an interesting new feature that Apple hadn’t told us about at WWDC: a new camera effect for video calls called Edge Light.

When this effect is enabled, the Mac displays a bright white border around the screen, intended to mimic the effect of a selfie ring light. As a result, the image captured by the Mac’s front camera looks better in low-light situations. We’ve already tested the new feature to see if it really makes a difference.

The new Edge Light effect appears alongside other existing camera options such as Portrait Mode, Studio Light, and Center Stage. According to Apple, the feature uses Neural Engine to detect the user’s face and adjust the light appropriately. It also detects the Mac cursor to hide the white light when necessary.

Does the Edge Light effect really make a difference?

But how effective is Edge Light? I tried using it in both ambient light and extremely low light. When there is already light, the effect is subtle and adds just a touch of extra brightness. But when you’re in a dark room, Edge Light can greatly improve your webcam image. Use the slider below to compare the two images:

The good news is that the new Edge Light effect in macOS works not only in FaceTime, but also with any other video app that supports existing camera effects. However, you need a Mac with an M1 chip or later to use it. It also works with external webcams and Apple Studio Display.

Another nice detail is that you can configure the intensity of the effect and also whether you want a warmer or colder light. On Macs with M4 chips and later, there is an option to automatically enable Edge Light when the camera detects a low-light environment.

In my experience, the feature works best with the latest MacBook Pros, which have brighter Mini-LED displays.

That said, don’t expect it to replace a dedicated ring light in all circumstances. If the room is already well lit or you are using studio lighting, the incremental benefit is modest. But for everyday use, occasional calls, and casual home office setups, the feature offers a smart, simple upgrade and highlights how Apple continues to refine the video calling experience on Mac.

macOS 26.2 is expected to be released to the public by the end of the year.
