Problems with "SF Symbols"

So, I’ve got it working again, finally. I’m not sure if all the things I did were necessary, but after several tries I did this:

  1. Close all applications.
  2. Delete the “FS Symbols” application.
  3. Delete all “FS…” fonts in /Library/Fonts
  4. Delete the Preferences of “FS Symbols” and “Font Book”.
  5. Delete everything in ~/Library/Caches
  6. Delete the font caches. In Terminal enter the following commands:
    $> sudo atsutil databases -removeUser
    $> sudo atsutil databases -remove
    $> sudo atsutil server -shutdown
    $> sudo atsutil server -ping

I found several tips on how to delete the caches, the above is a mix of all of them.

  1. Restart the Mac.
  2. On restart I reset the Parameter-RAM. I don’t know if there actually is something related to the problem stored there, but hey, I was desperate :wink:
  3. Start the Mac in “Safe Mode”. Press the shift key right after the start sound and hold it until the login screen shows. On the login screen you should see “Safe Mode” in the right top corner of the screen. If you don’t see this, try again.
  4. Login.
  5. After the login is complete, reboot again. This time don’t press any keys, just a normal reboot.
  6. Login. Install the “SF…” fonts again. Install “SF Symbols” again.

All this might be overkill, but now everything is working again.
