Mac showing special characters in menu items My Mac Pro is showing special characters "??????" in all my menu items. See image below: 



I am not sure how to fix this. Does anyone have any suggestions?
The easiest way to clear the font cache is to boot into Safe Mode. Restart your Mac while holding down Shift. 

Once the restart has completed, then restart normally.

Alternatively, you can run the following Terminal command, and then Restart:

sudo atsutil databases -remove


You will need to supply an admin password.
