Restoring the Frosted Glass Look
macOS relies heavily on translucency and blur effects (often called “vibrancy”) to give the operating system a sense of depth and modernity. You see this frosted glass effect in the menu bar, the Dock, the sidebar of Finder windows, and in Notification Center. Sometimes, users enable the “Reduce transparency” accessibility setting to improve text legibility, increase contrast, or slightly boost performance on older Macs.
When “Reduce transparency” is enabled, all of these beautiful blur effects are replaced with solid, opaque colors (usually flat grey or stark white). If you previously enabled this setting for troubleshooting, or if someone else turned it on, you might find the resulting flat, utilitarian look visually unappealing. You can easily disable this accessibility feature to restore the rich, translucent aesthetics of macOS.
How to Disable Reduce Transparency
You can manage this setting within the Display Accessibility options.
- Click the Apple Logo in the top-left corner of the menu bar and select System Settings… (or System Preferences).
- Scroll down the left-hand sidebar and click on Accessibility.
- In the main pane, under the “Vision” section, click on Display.
- Look for the toggle switch labelled Reduce transparency.
- Toggle the switch to the Off position.
The change takes effect immediately without requiring a restart. Your menu bar, Dock, and application sidebars will instantly revert from solid opaque colors back to their default, semi-transparent frosted glass appearance, adapting to the colors of your desktop wallpaper.
