How do I change the Finder font in OS X?

Today is a very personalized little tip, like all Mac apps, the Finder uses the Lucida Grande font. But you can change the font that the Finder uses. See how MACGG changes the Finder font.

Change Finder entire main interface font

Except for the Finder icon, all of us have changed. Open the terminal (Application-> utility), and then enter the following command:

Defaults write Com.apple.finder nssystemfont-string americantypewriter;

Killall Finder

This time I used the American typewriter font, you can change what font you want to use according to your liking.

Change the font of the Finder title bar

Open the terminal (Application-> utility) and enter the following command:

Defaults write Com.apple.finder nstitlebarfont-string arialblack;

Killall Finder

This time using the Arial Black font, note that if you use other fonts in the command, please remember to remove the space between them.

You can also change their font size, and you can change the font size to 16 by using the following command:

Defaults write Com.apple.finder nstitlebarfontsize 16;killall Finder

Restore default Settings

If you don't like the change, or want to revert to the default font Lucida Grande font, open terminal, enter the following command:

Defaults Delete Com.apple.finder Nssystemfont

Defaults Delete Com.apple.finder Nstitlebarfont

Defaults Delete Com.apple.finder nstitlebarfontsize

Killall Finder
