On your Mac, you can utilize Font Book to manage macOS fonts by creating collections that group them based on specific themes, such as those used for a certain website or fonts that emulate handwriting styles. In the sidebar, you'll find default collections that help you navigate through your font options. A Smart Collection automatically organizes fonts by certain criteria like style and family name, ensuring that any font fitting those parameters is included without manual effort. Additionally, you can establish a font library to keep fonts organized, especially if they are intended for a particular document. This allows for an efficient workflow when working on specific projects. The interface also features a grid that displays available characters and symbols, or glyphs, and you can easily adjust the size of the preview by dragging the slider located to its right. By utilizing these tools effectively, you can enhance your font management experience significantly.
