BrightIntosh Overview
BrightIntosh for Mac is a small open source utility that unlocks the full brightness of your MacBook Pro's Liquid Retina XDR display. Normally macOS only allows that peak brightness, up to 1000 nits, when playing HDR video content. BrightIntosh removes that restriction so the extra brightness applies to everything on screen, from your desktop to regular apps. It works through the menu bar with one click controls, keyboard shortcuts, and optional automation tied to whether your Mac is plugged in or running on battery. It suits anyone who works outdoors, in bright cafes, or simply wants a noticeably brighter screen indoors without switching to HDR content first.
Why Choose BrightIntosh for Mac?
The technical detail competitors often skip is exactly how BrightIntosh achieves this. It places a tiny one pixel HDR overlay hidden behind your display's rounded corner, which tricks macOS into activating its HDR brightness mode system wide. Gamma values are then adjusted so the extra brightness applies across all content, not only HDR video, all while macOS stays in full control of the actual display hardware.
The other important gap is device compatibility, since this is not a universal Mac utility. BrightIntosh only works on specific MacBook Pro models from the M1 generation onward, plus the Studio Display XDR in beta and the Pro Display XDR. Regular MacBook Air models and older Intel based Macs cannot use it at all, since they lack the Liquid Retina XDR hardware the trick depends on. Checking your exact model before downloading avoids a wasted install.

Supported macOS Versions
BrightIntosh requires macOS 14.6 or later and only supports MacBook Pro models built around the Liquid Retina XDR display, starting from the 2021 M1 generation through the current M5 lineup, plus the Studio Display XDR and Pro Display XDR as external monitors. A simple way to check compatibility is looking for a notch on your MacBook's display and confirming it says MacBook Pro on the underside. There is no separate Intel build, since every supported device already runs on Apple Silicon.
