First I have a fresh new install on my mac : from formatted HD => mac OS => adobe CC.
I have some fonts installed I don't understand from where or how they could come from.
For exemple : Birch (I must have +/- 50 fonts like this)
It's not an apple font.
it's on typekit but I don't have this font synced in my list of synchronised fonts in my typekit account.
I don't see any other possibilities than it came with my adobe CC installation.
BUT, after reading FAQ and articles about fonts and Adobe CC, nothing seems to install adobe fonts (except sync with Typekit)?
So, I really don't understand what this font is doing on my computer ?
I want to have a clean font directory with everything ok for licenses and it's hard to do if I can't know from where some fonts are coming...
Thanks for any help, I've searched for days now.
PS : sorry if my English is not very good, I'm French.
I don't believe these fonts are coming from Typekit as they wouldn't show up in your font directory even if they were synced. You said this was a fresh install, one thing you could do is remove any fonts not listed here: List of typefaces included with macOS - Wikipedia unless you remember where you got them and have the license for them.
Birch is definitely not installed with CC as outlined here: Creative Cloud fonts, installation & FAQs | Adobe Type
I hope that helps. Let us know if you need anything else.
