iBrightness is a software utility primarily designed to manage and automate screen brightness levels on computers. Depending on your operating system, it refers to one of two different lightweight tools: iBrightness for Mac
This Utility App is specifically built for portable Macs like the MacBook Air and MacBook Pro. It provides more granular control than the built-in macOS settings by allowing you to:
Automate Power Transitions: It sets specific, separate brightness levels for when your Mac is plugged in versus when it is on battery power.
Menu Bar Access: You can adjust brightness levels directly from the macOS menu bar rather than diving into System Preferences.
Override Default Behavior: It is designed to fix the “gap” in early macOS versions where the system would sometimes revert to its own perceived “correct” brightness even if automatic brightness was disabled. iBrightness Tray for Windows
On Windows, iBrightness Tray is a free, small utility (often called a “Swiss Army knife” for display tools) that sits in the system tray. Its core features include:
Slider Control: Adds a quick-access slider to the taskbar for adjusting brightness.
Screensaver Trigger: One-click button to immediately start the screensaver or turn off the monitor to save power.
Ease of Use: It was particularly popular for older versions of Windows (like Windows 7 and 8) that lacked the streamlined brightness sliders found in modern Windows 10 and 11. iBrightness – App Store
