下一版macOS更新可将您的屏幕变为环形补光灯。
内容总结：
苹果新版macOS将引入屏幕补光功能，助力线上会议形象升级
在即将发布的macOS更新中，一项名为"边缘补光"（Edge Light）的创新功能引发关注。该技术可将MacBook屏幕转变为智能环形补光灯，为视频会议场景提供专业级的面部光线优化。
据悉，这项功能通过激活屏幕边缘的矩形光带实现补光效果，并依托苹果神经网络引擎实时追踪用户面部位置，自动调整光源角度。用户可根据环境需要调节色温参数，系统还支持环境光线变暗时自动开启补光模式。
值得注意的是，该功能在设计上充分考虑了使用便利性：补光区域将自动避开顶部菜单栏，当光标悬停时光源会智能避让，确保视频通话同时不影响正常电脑操作。不过此项功能仅支持2024年后发布的苹果自研芯片版MacBook设备。
虽然无法完全替代专业环形补光灯，但这一创新方案显然比临时打开空白文档充当补光板的应急做法更为优雅实用，展现出苹果在系统细节体验上的持续优化。

下一代macOS更新可将屏幕变为环形补光灯
这个设计颇具巧思。
有时，操作系统最出色的功能并非发布会上那些华而不实的演示，而是那些能自然融入使用场景的细腻改进。即将到来的macOS更新中就出现了这样的功能——Tahoe 26.2开发版测试系统搭载的"边缘补光"功能，可让电脑屏幕在视频通话时化身环形补光灯。
这项功能通过屏幕边缘的矩形光带实现照明效果，苹果神经网络引擎会根据人脸在画面中的位置自动调节光效。用户可调节冷暖色调，当环境光线变暗时还能启动自动开启模式。边缘补光会避开顶部菜单栏，当光标悬停时也会自动避让，确保视频通话时电脑仍可正常操作。
该功能仅支持2024年后发布的苹果芯片版MacBook。虽然无法完全替代专业环形补光灯，但比起临时打开一堆空白谷歌文档来打光的应急方案，这无疑是更优雅的解决之道。

The next macOS update can turn your screen into a ring light
It's a bright idea.
Sometimes, the best features in a new operating system aren't the flashy ones that get broadcast during a keynote. They're subtle improvements that naturally fit into how you use your device and just make the experience better. One of those appears to be coming in the next macOS update. The dev beta of Tahoe 26.2 includes a feature that essentially lets your computer screen function as a ring light during a video call.
It's called Edge Light and it illuminates a rectangular band around the edge of the screen. Apple's Neural Engine will also position the light based on where it detects your face in the video frame. There are some controls for making the light warmer or cooler, and it can be set to turn on automatically once the brightness in your environment dims. Edge Light doesn't cover the top menu bar, and it will also move out of the way if the cursor hovers over it so that you can still use your laptop normally while on a call.
Edge Light will only be available on MacBooks from after 2024 that are running on Apple's Silicon. It may not be a true replacement for a ring light, but it's probably a step up from opening a bunch of blank Google Docs to try and illuminate yourself for a last-minute meeting.
