Right click on the font and select Validate Font .
One of the three icons is displayed next to each font on the Font Validation window:
To resolve triggered and disabled alerts and errors (the next section will show you how to disable fonts), select the font and click Remove Checked .
If you have a long list of authentic fonts, there is a way to make it easier for you to find problematic fonts. Select Warnings and Errors from the list at the top of the Font Validation window.
To validate the font file before installing, open Font Book and go to File> Validate File . Select the file and click Open . Font Validation window displays the status of the font file. Then, you can install that font, if you want, on the Validation Font window by selecting the font and clicking Install Checked . We recommend that you do not install fonts that display warnings or errors after authentication.
If you decide you don't want to use a font anymore, but you don't want to delete it, you can disable that font.
First, select the font (s) you want to disable. Then, do one of the following:
Note: System fonts cannot be disabled.
The disabled fonts are displayed in light gray and labeled Off . They are not deleted from your Mac but they cannot be used in applications.
If there are fonts you don't want to be on your Mac, you can delete them.
To remove the font in Font Book, select that font and do one of the following:
Note : The system font cannot be deleted.
Click Remove on the display confirmation dialog.
Deleted fonts will be transferred to Trash and not in Font Book or in applications.
If you are having trouble with any of the fonts you have installed in Font Book, you should restore the fonts that were originally installed on your Mac. This will move the fonts you have installed into a separate folder, making them no longer available for use in the application.
Open Font Book and go to File> Restore Standard Fonts .
Click Proceed on the confirmation confirmation dialog.
You are informed that the standard font has been restored. Click OK .
Other fonts are moved to a folder in the user's Library, ~ / Library / Fonts (Removed) or the machine's main Library directory, / Library / Fonts (Removed) , depending on where it is installed.
To reinstall the deleted fonts, reinstall them using one of the methods we mentioned above.
If you want to install fonts manually, you can copy the font files into the appropriate Fonts folder on your Mac.
To set the font only for your use, copy the font file and go to the / Users / Username / Library / Fonts folder, replace the Username with your username. If you want the font to be available to all users, go to the / Library / Fonts folder on the Mac hard drive.
If you don't see the Library folder in the Finder , open the Go menu , press and hold the Alt key to make the Library available on the menu. Then select Library . You can also make the Library folder available permanently in the Finder.
Paste the font file into the Library folder by right-clicking and selecting Paste Item or by pressing Ctrl + V.
Manually installed fonts are now available in the application. For example, this is the NewStyle font used in Word documents.
