The True Tone technology in Mac computers, Studio Display, and Apple Pro Display XDR uses advanced multichannel sensors to adjust the color and intensity of your display and Touch Bar to match the ambient light so that images appear more natural.
- Choose Apple menu > System Preferences, then click Displays. If you have multiple displays connected, click Display Settings, then select your display.
- Use the True Tone checkbox to turn this feature on or off. It appears only on displays that support True Tone.
