How to Make Your Mac Screen Brighter

Check the Mac’s native brightness controls and display settings first.

Check the settings

Automatic brightness, Low Power Mode and reference modes can affect the available range. Change only the settings that suit your current work.

Use Lumi’s beta on tested hardware

Lumi adds a menu bar slider with estimated nit targets and keeps the Mac’s normal brightness keys and indicator. The tested M2 Pro profile has a 1,600-nit peak target; that is not a guarantee of full-screen output.

Know the current limits

The beta controls built-in panels only. OLED and other hardware still need physical validation. See the installation and support notes before trying it.
