Mac OS X El Capitan, Suitcase Fusion 6. There’s a small LOCK icon on my systems fonts in Suitcase Fusion 6. What does it mean and how can I lock/unlock?
In El Capitan, fonts labeled with the LOCK icon are permanently activated and REQUIRED by the OS. With El Capitan, Apple added System Integrity Protection and those fonts can’t be deactivated through Suitcase Fusion. For more, Kurt Lang’s article on font management has a lot of good information on managing your OS X system fonts.
Thank you very much!
