Your Mac comes with many preinstalled fonts, styles of type that your computer uses to display and print text. Use Font Book to sort and preview your font collections to find the right one to use for your project. Font Book allows you to easily take a peek at what all your installed fonts look like. Font Book also lets you install, search, organize, activate, and deactivate fonts too. When you open it, the interface displays a Collection column on the left that sorts fonts by category, a Font column in the middle that displays all fonts in the selected collection, and a preview pane on the right, which displays a sample of the characters in the selected font. Here are a few ways that you can use Font Book.
