Do fonts take up much space, and how do I remove ones I don't use?
Short answer: Fonts are small, but big collections add up. Remove ones you installed and don't use in Font Book; system fonts are protected.
Individual fonts are small, but large font collections installed by design apps can add up. Open Font Book, select fonts you installed and don't use, and choose Remove (or press Delete).
System fonts are protected and can't be removed. If an app needs a font you removed, it will warn you when you open a document that uses it.
