How do I hide or disable or delete all the foreign fonts on my Air?
MacBook Air 13″, macOS 11.6
Many of the fonts on your Mac were installed with the Mac's OS and cannot be removed. All you can do is to open the Font Book app and disable those fonts it will allow you to. Then they do not show up. Beyond that, there is nothing else you can do.
If you mean the ones like the 100 Noto Sans fonts, you have to use a third party font manager as Font Book won't even show those, much less let you choose to disable them. Those that can control the fonts in the /System/Library/Fonts/Supplemental folder are:
Typeface
RightFont
Connect Fonts
FontAgent
Personally, I use Typeface.
In the upcoming Ventura, it appears Apple is going to automatically hide all of these fonts from all apps. Or at least, that seems to be the intention. Such as, the app Ultra Character Map hasn't had an update for quite a while, and yet it already doesn't list any of those fonts in the Ventura beta. Photoshop CC shows all of them (at this point). While folks have used these fonts for years (after all, they appear, so why not?), they've never been there for the user. They're mostly backward support fonts.
Anyway, the point of all of that is whatever font manager you purchase now to disable those fonts will not work in Ventura. I tested a few, including Typeface, and the OS will not let you even simply disable those fonts.
