Remove, deactivate, or activate fonts in Font Book on Mac
When you remove fonts from your Mac, they aren’t available in Font Book or in the Fonts window. If you don’t want to remove a font, you can deactivate it (or turn it off)—deactivated fonts remain on your Mac, but appear dimmed in the Fonts window. If you change your mind later, you can activate (or turn on) the fonts again.
Important: You can’t remove or deactivate system fonts. See the Apple Support article Fonts included with macOS Sonoma.
