Fonts in OSX
Installing fonts without font management software
It is possible, though perhaps not advisable, to install (activate) fonts without a Font Management Program. For single users you could copy the fonts into the /Users/[name]/Library/Fonts folder.

You could create an alias to this folder on your desktop or add the folder to the Sidebar. Add fonts when needed, take them out when finished. Fonts can be in a sub-folder for ease of organisation. If you are using an OS prior to 10.4 keep the fonts only one level deep.

Font management programs
Font Book
Mac OSX 10.3 and higher includes a basic form of font management in the Font Book program. This program is easy to use and may be all you need if your font library is small. However, it does not offer auto-activation or any of the commercial utilities.

Before using Font Book set its preferences to install fonts by
copying. (Later versions of Font Book install by copying and it is not a selectable preference).
Font Book allows you to preview, install, organise, activate and de-activate fonts. If a font is causing problems Font Book allows you to Validate fonts showing results in a Font Validation window.
