Font Book finds duplicate fonts installed by Microsoft Office Once you install Microsoft Office on a Mac, you get a bunch of new fonts. This is great, except many of them conflict with existing fonts that shipped with OS X.


Open Font Book.
Select all fonts in the middle column.
File > Validate Fonts.


This is an example of what I'm talking about:



For every conflict the same font is located in each of the following folders:


/Library/Fonts/
/Library/Fonts/Microsoft/


Obviously, one way to resolve this conflict would be to choose one and remove the other. Or I could just leave it alone, since I really didn't notice the issue until just now when I tried validating my fonts -- they are the same fonts after all.

What are the pros/cons/considerations of each solution I've proposed? Is there a third way? How do you prefer to deal with this?
If you want to save space and remove the extra fonts, I'd recommend selecting everything, then right-clicking and selecting "Resolve Duplicates." I'm fairly sure Font Book favors fonts without any detectable bugs and with more characters, but in any case it will automatically disable any duplicate fonts.
