Modern MacBooks and iMacs are equipped with high-density Retina displays, offering incredible sharpness and clarity. However, Apple’s default scaling settings are designed to balance text readability with screen real estate. If you find the text too small to read comfortably, or conversely, if you need more space on your screen for multiple windows, you must know how to change your Mac’s display resolution.
Understanding Retina Scaling
Unlike older monitors where changing the resolution actually lowered the pixel count (resulting in a blurry image), macOS handles Retina displays differently. It uses “scaling.” This means the physical pixels on your screen remain razor-sharp, but the operating system artificially magnifies or shrinks the user interface elements (like text, icons, and menus) to simulate a different resolution.
Step-by-Step: Changing the Resolution
The process is straightforward, but the exact location of the settings depends on your version of macOS.
For macOS Ventura, Sonoma, and Later:
- Click the Apple logo () in the top-left corner of the menu bar.
- Select System Settings.
- Scroll down the left-hand sidebar and click on Displays.
- You will see a series of thumbnails representing different sizes. These range from Larger Text (which makes everything bigger and easier to read) to More Space (which shrinks elements so you can fit more windows on the screen).
- Click the thumbnail that best suits your needs. The screen will briefly flicker as the new scaling takes effect.
For macOS Monterey and Earlier:
- Click the Apple logo () and select System Preferences.
- Click the Displays icon.
- Look for the ‘Resolution’ setting and change it from ‘Default for display’ to Scaled.
- Select your preferred scaling option from the options provided.
Accessing Hidden Resolution Options
By default, Apple only shows you a few curated scaling options that maintain the correct aspect ratio of your screen. If you are connecting to a third-party external monitor or projector, you might need access to specific numerical resolutions (like 1920×1080 or 2560×1440).
To reveal every possible resolution your monitor supports:
- Navigate to the Displays settings page using the steps above.
- Instead of just clicking on an option, press and hold the Option key on your keyboard.
- While holding the Option key, click the Scaled button (or right-click the thumbnails in newer macOS versions and select ‘Show List’).
- A much longer, detailed list of numerical resolutions will appear. Select the exact resolution required by your external display.
Troubleshooting External Monitor Issues
If you connect a non-Apple external monitor and the text looks blurry or jagged, consider this:
- Font Smoothing (Subpixel Antialiasing): Apple recently removed subpixel antialiasing from macOS, as their Retina displays no longer need it. However, if you are using a standard 1080p external monitor, this can make text look terrible. If changing the resolution does not help, you may need a third-party utility like BetterDisplay to force higher-quality rendering on non-Retina screens.
By adjusting your display scaling, you ensure your Mac provides a comfortable, productive workspace tailored to your specific eyesight and workflow requirements.
