You use a fonts management software such as Extensis Suitcase or similar to select, preview and load the font you want to use. It can even scan for corrupted fonts to prevent systems crash. The loaded fonts will be shared with other applications, not only Photoshop. It's not a good idea to load all the fonts in the System and just use a few, it will slow down your computer, or even crash.
