You can add custom fonts to macOS by following these steps: Download the font files you want to add. These are typically in .ttf or .otf file formats. Open the Finder and click on “Go” in the menu bar at the top of the screen. Select “Go to Folder” and type “~/Library/Fonts” in the dialog box. Press enter. Drag the font files you downloaded into the Fonts folder. Close the Fonts folder and open an application like Word or Photoshop. You should now be able to select and use the newly added fonts in the application’s font menu.

You can also add fonts to a specific user account by replacing the step 3 by: 3. Open the Library folder in your home directory by holding down the Option key and choosing Library from the Go menu.
