Office 2011 Font Management with Mavericks

Dealing with Duplicates

Currently, the Office 2011 installer removes some Apple duplicate fonts and moves them to Fonts Disabled folder in the main Library. This helps with the duplicate font issue, but they don’t remove all duplicates.

In addition to the fonts that were disabled by the installer, you also need to disable  the following duplicate fonts from the Library/Fonts/Microsoft folder. A newer version TrueType font is available in the Library/Fonts folder.

  • Andale Mono
  • Arial Black
  • Arial Narrow
  • Arial Rounded Bold
  • Comic Sans MS
  • Georgia
  • Gil Sans Ultra Bold
  • Impact
  • Tahoma
  • Trebuchet MS

Font Book shows Bauhaus 93 with warning. You might want to disable it as well.

Delete font caches using a utility like Font Nuke and restart after deleting fonts!


Microsoft Office installs fonts in this location:

  • Library/Fonts/Microsoft

Microsoft Office 2011 fonts are installed in the Library/Fonts/Microsoft folder. The advantage of placing fonts in the root font folder gives all users on the machine access and Office doesn’t install multiple copies on the machine for each User.

Fonts installed by the OS include many of the same named fonts Office installs on your system resulting in duplicates. The fonts installed by the OS are often the larger TrueType fonts. Office can use either type of font. 

  • Office does not need ANY of its fonts to “run.” However, various features of Office will be broken or display poorly unless you leave the fonts it installs in place.
  • I would caution you not to disable the Chinese/Japanese fonts. These are required to produce certain special characters.
  • It’s important to deal with duplicate fonts or you could experience crashes with the Office applications.
  • After you delete or disable fonts, it’s important that you delete font caches and restart your computer! (Use a utility like Font Nuke to delete font caches)

Verify with Font Book

I recommend that you run Validate Fonts using Font Book to see there are other duplicate or problem fonts. Adobe is another app that installs fonts that could be old or duplicate fonts.

You can select to let Font Book resolve automatically or resolve manually. Automatically could result in removing a newer font rather than an older font.



How to use Font Book to validate fonts

  1. Open Font Book in your Applications folder.
  2. Select All Fonts.
  3. Now click in the list of fonts and select all (Edit > Select All).
  4. Under File in the Menu bar, select Validate Fonts.
  5. Duplicate fonts will be marked with either the yellow badge or a black dot.
  6. Select to remove or delete duplicates.*
  7. Delete font caches (how to)
  8. Restart your computer

Troubleshoot Fonts

If you want to eliminate fonts as a cause of crashes in Microsoft Office applications, boot using Safe Boot mode. In order to boot into Safe Mode, hold the Shift key immediately after restarting or pressing the power button. When booting into safe mode it forces your computer to run various maintenance tasks. (These are some of the items disabled on safe boot:)

  • Disables all fonts other than those in /System/Library/Fonts
  • It moves to the Trash all font caches normally stored in /Library/Caches/
  • Disables all start-up items and Login items

If your crashes went away while booted in safe boot mode, check for duplicate fonts and delete font caches. Delete font caches using a utility like Font Nuke and restart after deleting fonts!
