Changing Fonts in OSX

[CrackedButter]

I was trying to change the appearance of my mac but i cannot for the life of me find the option of changing the system fonts and playing with AA for fonts. I've looked all over System Preferences to no avail.

My main aim is to have a different font to the one already implemented on the system. Thanks in advance.
Anybody care to share this info?

This is not an Apple System Preference. You'll need to download TinkerTool to mess with this stuff. (I'd find a link for you, except that you can get one just as easily by doing a search for TinkerTool.)

Be careful with tinkertool or any other system hack or modifier. They can and often cause system problems especially with new system and program updates.
