Your Mac’s brightness can be adjusted in a few key locations. The most immediate way is often through the Control Center. Click the Control Center icon in the menu bar. You’ll see a brightness slider. Dragging this slider left or right will decrease or increase the screen’s brightness, respectively.
Within the “Displays” section of System Settings, you’ll find a dedicated “Brightness” slider. This offers more precise control and is often complemented by an “Automatically adjust brightness” toggle. When enabled, your Mac will use its ambient light sensor to adjust screen brightness based on the surrounding light conditions. This is incredibly useful for maintaining comfortable viewing in varying environments and can also help conserve battery life on MacBooks.
Color Balance and Tone
The “Color” section within the Displays settings allows you to fine-tune how colors appear on your screen.
The “Color Profile” dropdown menu is particularly important for professionals who rely on accurate color representation, such as photographers, graphic designers, and video editors. macOS comes with a variety of built-in color profiles designed for different use cases. For general use, the default profile is usually sufficient. However, if you have a colorimeter or spectrophotometer, you can calibrate your display and create custom color profiles for unparalleled accuracy.
You might also find options for “True Tone” on compatible Mac models. True Tone technology automatically adjusts the color and intensity of the display to match the ambient light, making images appear more natural.
Advanced Display Configurations: Resolution, Refresh Rate, and More
Beyond brightness and color, macOS offers advanced settings to tailor your display’s resolution, refresh rate, and other performance-related aspects.
Resolution and Scaling
Under the “Display” settings, you’ll find options related to resolution. For most users, the default “Default” setting is ideal, as it provides the sharpest and clearest text and images for your specific display. However, you can choose to scale the display to make text and icons appear larger or smaller. This is especially useful for users with vision impairments or for those who simply prefer a different visual density.
Clicking on “Scaled” will reveal several options, often presented as descriptive text like “Larger Text” or “More Space.” These options effectively change the effective resolution of your display, making elements appear bigger or smaller without actually altering the physical pixel count. Experiment with these options to find what works best for your eyes and your workflow.
For external displays, you may have more control over the resolution, allowing you to select from a range of supported resolutions.
Refresh Rate
For MacBooks and iMacs with ProMotion technology, you can adjust the refresh rate. The refresh rate determines how many times per second your display updates its image. A higher refresh rate results in smoother motion, which is particularly noticeable in scrolling, animations, and gaming.
In the “Displays” settings, you’ll typically find a “Refresh Rate” dropdown menu. Options may include 60Hz, 120Hz (for ProMotion displays), and potentially other values depending on your Mac model and the connected display. Choosing a higher refresh rate offers a more fluid visual experience but can sometimes consume more power.
Arranging Multiple Displays
If you use more than one display with your Mac, the “Displays” section is where you’ll configure their arrangement and primary display.
Once your external displays are connected and recognized, they will appear as thumbnails within the “Displays” settings window. You can drag and drop these thumbnails to match the physical placement of your monitors on your desk. This ensures that moving your mouse cursor between screens feels natural and intuitive.
You can also designate a “primary display” by dragging the white menu bar from one thumbnail to another. The primary display is where the Dock and menu bar will appear by default.
Color Calibration and Accessibility
macOS provides robust tools for color calibration and offers various accessibility features that can significantly impact how you perceive and interact with your display.
Color Calibration Assistant
For users who need precise color matching, macOS includes a built-in Color Calibration Assistant. To access this, go to System Settings > Displays > Color > Calibrate Display.
