How to remove a font downloaded through Font Book?

Question

Font Book has a few international fonts that need to be downloaded before use. After downloading one there is no immediate way to remove it again. Can this be worked around?

Answer 1

You can replace them with themselves, but manually installed, with the shell command:

cp /System/Library/Assets/com_apple_MobileAsset_Font5/*/AssetData/* ~/Library/Fonts/

Then, from the “User” section of the sidebar, select all of the fonts you want to remove, and the system-installed version should be removed as well. An alternative way is to resolve the duplicates by keeping the manual version, and then removing that as well.
