I just finished a group video call with my siblings in an utterly dark cabin surrounded by pine trees. And for the first time, I didn’t hear a complaint that goes something like “please turn up the brightness, I can’t see your darn face.”
It was the same Mac as usual, my go-to video call app, and a familiar cellular internet situation. The only difference this time around was the new display-driven light fill feature that has arrived with the macOS 26.2 update, which is now rolling out widely to Mac users.
Apple calls it Edge Light. Think of it as a ring light, but one that lives within your Mac’s screen and happens to be rectangular in shape. It’s the first time I’ve tried a solution like this on a PC, after giving the version a try for low-light selfies. To my surprise, it worked pretty well.
Does it work?
Well, to answer that query up front, here’s a snapshot from the same dark work cave. On the left is a Photo Booth capture in regular mode, and on the right is the same frame with Edge Light enabled. You can see a stark difference:
Now, before we get into the nitty-gritty, here’s a small nugget of bad news. The Edge Light feature is limited to Macs with the M-series silicon. So, if you’ve got an older machine with an Intel processor, you’re out of luck. Why?
Apparently, this feature is not all about enhancing the brightness using the display hardware at hand. Instead, it does dynamic light adjustment based on the ambient light situation and the user’s position in the frame. And that requires a powerful chip to handle.
“Apple silicon enables this feature to be extra smart. The Apple Neural Engine detects faces, their relative size, and where they are located in the camera feed, and the Image Signal Processor understands light levels very precisely to adjust the auto brightness level depending on the light that’s needed in the scene,” Apple said in a statement shared with Digital Trends.
Another aspect that you must keep in mind is that the mileage will vary depending on the Mac display you’re facing. The Pro models with their brighter mini-LED panels will offer a stronger illumination with the Edge.
I tried using the M4 iPad Pro (OLED screen) as a secondary display and clearly noticed the difference compared to my M4 MacBook Air. Moreover, if you have a bigger display, the brightness output between a 13-inch laptop screen and a 24-inch monitor would be even more apparent.
A clear difference
Let’s dig into the effectiveness of the new Edge Light system in macOS Tahoe (version 26.2). First, it works with any video calling app of your choice. Whether it’s Google Meet or FaceTime, the tool works just fine.
In fact, any app that triggers with a webcam also activates the Edge Light system. All you need to do is tap on the green video camera icon that appears in the Menu Bar at the top. On Macs that fall within the 2024 model year portfolio, or newer, the system can be set to activate automatically.
On these Macs, the device analyzes the ambient lighting situation and automatically activates the light halo alongside the edges. As far as controls go, you can adjust the brightness output and the color temperature, as well, going from bright white to a soothing warm shade.
The brightness situation is slightly tricky. You see, instead of decreasing the halo light’s brightness, Apple reduces the thickness of the virtual light strip. It’s a clever way to keep the system-wide brightness level intact, so that if you’re working intentionally at a low/high brightness mode, the Edge Light strip won’t interfere.
For optimal output, keeping the display brightness level at nearly the halfway mark works fine at lighting up your face. But if you want the best results, crank the brightness levels all the way to the max value to get the best out of the edge light strip.
I preferred the soothing yellow glow by keeping the temperature warm. It’s easier on the eyes and delivers a more natural look. But if you truly need to light up your face, set the color slider towards the white or blue end of the slider.
Like me, if you prefer working from a dark room, away from the flash and glitz of overhead lights, Edge Light is nothing short of a savior. You don’t need any extra gear to illuminate your face for video calls.
Over the past couple of months, I’ve traveled extensively in remote areas. For the brief video calls with family or recording a quick vlog, I loved the added flexibility at hand.
Yes, Edge Light is not going to beat the sheer brilliance of a physical ring light, but it can certainly pull your face from a grainy darkness into a well-lit camera view. But that’s not the point. It’s an assistive tool that can significantly enhance the visual quality of your video calls, especially if you’re using a dedicated webcam.
A clever little trick
The Edge Light feature that arrived with macOS Tahoe (26.2) does its job well. But it’s also hiding a thoughtful trick. “The light is smart, receding from your mouse pointer when you get close to the edge of the screen, so you can always access your content,” Apple tells me.
Simply put, a small area of the light halo will automatically darken based on the position of the mouse cursor. So, let’s say you have FaceTime and Google Docs open in split view mode on the screen, and you’re referencing a document for the conversation.
As soon as the system detects that the cursor is on the left side of the screen (in the Google Docs window), the left edge of the halo light darkens. This thoughtful change ensures that the bright light isn’t perceived as bleeding into the other window where it’s not needed.
It’s almost like Edge Light is keeping the “blinding lights effect) in check. I really love this small, but significant design decision. Edge Light can also be combined with Studio Light effect for an even better experience in video calls, especially if you are moving but need a tracking illumination.
Overall, macOS 26.2 isn’t quite the feature-loaded update. But Edge Light makes it one of those small incremental updates that are worth chasing. Neat job there, Apple!
