How to Turn Off the Glowing Apple Logo on the New MacBook Pro

Apple Reintroduces the Illuminated MacBook Pro Logo With OLED-Driven Hardware

Apple has brought back the glowing Apple logo on the lid of the newly released MacBook Pro, approximately ten years after removing the design element during the 2016 redesign, WinFuture reported. Unlike legacy models where light bled through the display panel from the internal backlight, the current generation utilizes a separate OLED-based illumination architecture tied directly to the computer’s display state and ambient light sensors.

The Tech TL;DR:

• The glowing Apple logo returns on the latest MacBook Pro lineup after a decade-long absence since the 2016 redesign.
• Because the new notebooks use OLED panels rather than traditional backlights, the logo requires a separate software-controlled illumination circuit modulated via pulse-width modulation at 25 kilohertz, as discovered by developer Guilherme Rambo.
• Users wishing to turn off the glowing emblem in dark environments can do so via a system-wide Terminal command, as no toggle exists in the standard macOS System Settings.

The technical implementation relies on system-level software integration rather than simple passive light collection. According to developer Guilherme Rambo, cited by ComputerBase, the logo is modulated at 25 kilohertz using pulse-width modulation through the macOS component CoreBrightness. The system applies individual factory calibration to each device, adjusting the luminosity dynamically based on the laptop’s specific enclosure color and real-time data from the internal ambient light sensor. In darker environments, the symbol dims noticeably, while brightening automatically near sunlit windows.

Terminal Command Bypasses Missing System Toggle for Logo Deactivation

Despite the automatic sensor adjustment, the glowing lid can prove distracting in dark studio environments or professional meetings. Because Apple provides no dedicated switch within the standard graphical System Settings panel, turning off the feature requires executing a command-line instruction in the macOS Terminal utility.

To disable the illumination permanently across all user profiles on the machine, users must execute the following command with administrative privileges:

sudo defaults write com.apple.CoreBrightness LEBacklightMode -int 0

According to Apple’s official support documentation, the modification takes effect immediately upon authentication with an administrator password and persists through reboots as well as recovery mode sessions.

Executing Terminal Command Restores Default Glowing Apple Behavior

Restoring the glowing emblem requires a separate command to remove the preference key. Executing sudo defaults delete com.apple.CoreBrightness LEBacklightMode in the Terminal returns the hardware to its default dynamic behavior.

The return of the illuminated apple marks the reversal of a design shift that began nearly a decade ago. The feature first appeared in 1999 on the PowerBook G3 model codenamed “Lombard,” utilizing light passing through a translucent aperture from the active screen. Apple phased out the illuminated symbol beginning with the 12-inch Retina MacBook in 2015, followed by the October 2016 introduction of redesigned 13-inch and 15-inch MacBook Pro models that featured polished metal emblems instead. The current PROLED XDR generation reinstates the illuminated branding via active OLED modulation.
