system folder read-only
As already stated, Font Book does not allow users to delete fonts in the System folders."You can’t remove or disable system fonts."
Remove, deactivate, or activate fonts in Font Book on Mac
In Font Book on your Mac, you can remove, deactivate (turn off), or activate (turn back on) fonts.support.apple.com
That might have worked with older macOS. But with Big Sur you need to explicitly mount the read-only system volume as read/write, break the cryptographic seal and then start changing things. And, of course, reseal the system so it will boot. Only works if you do not use FileVault. And will be replaced with the next minor update of BS.this method
Good question, and I don't know the answer. I've been using whatever the default font list display in InDesign is. I'll see what I can find out, although I remember that when I was exploring it on InDesign/Adobe sites, the complaints were just like mine, and I saw no solution. But that was about a year ago.Applications like Apple's Pages and Microsoft Word are aware of font collections created in the Font Book utility. Using font collections removes the need for scrolling at the expense of an extra click or having a font widget on screen.
Is InDesign aware of font collections?
