Apple's spec for the 14-inch MacBook Pro (2021) lists 1,000 nits sustained full-screen brightness for HDR content, but only 500 nits for everything else. macOS keeps the top of that range for HDR video. BrightIntosh is a free, open source app that shifts your everyday brightness range into it, any time you want.
Here is what you get, how to set it up, and the catch.
What you get
- Your whole screen can use the brighter XDR range, not just HDR video. Handy outside or in a bright room.
- A menu bar toggle to switch it on and off, and a slider for how far it shifts the range.
- Your brightness keys keep working as normal.
- The developer says it uses no low-level API calls and macOS stays in full control of the display.
