Yes, but only indirectly with Apple’s own controls. Out of the box, the logo is lit whenever the Mac is awake with the lid open, and its brightness rises and falls with the main display. The ambient light sensor plays a part too, so the glow adjusts to the room you’re in.
That means lowering screen brightness dims the logo. It works, but it’s a poor trade, because you probably set your screen brightness for comfortable reading, not to hide a light on the back. There’s no separate slider for the logo in System Settings.
The free app that adds a real dimmer
Designer Juan Buis built an app called Backglow to fill that gap. The free version lets you:
- Set the logo’s brightness on its own, separate from the display.
- Switch the light off with a single click, no Terminal needed.
- Use a Breathe mode that slowly pulses the logo, a nod to the sleep light on older MacBooks.
- Use a Battery mode that fades the glow as your charge drops.
- Keep the logo lit even with the lid closed.
A one-time Pro upgrade costs $9 for a limited time, rising to $15 later. It adds a Music mode, where the logo pulses with whatever you’re playing, and an Agents mode that throbs gently while Claude Code is working and blinks when the AI coding tool needs your input. What no app can do is change the color: the light is a plain white LED.
If you only want the logo off, the Terminal command does the job for free with nothing extra installed. If you’d like it softer rather than gone, Backglow is the simpler choice.
