To create a new signature, click the Sign tool, click Create Signature if shown, then click how you want to create your signature:
Use a trackpad: Click the text when asked, sign your name on the trackpad using your finger, press any key when you’re finished, then click Done. If you don’t like the results, click Clear, then try again.
If your trackpad supports it, press your finger more firmly on the trackpad to sign with a heavier, darker line.
Use your Mac computer’s built-in camera: Hold your signature (on white paper) facing the camera so that your signature is level with the blue line in the window. When your signature appears in the window, click Done. If you don’t like the results, click Clear, then try again.
Use your iPhone or iPad: Click Select Device to choose a device (if more than one is available). On your device, use your finger or Apple Pencil (on iPad) to sign your name. If you don’t like the results, tap Clear, then try again. When you’re ready, tap Done.
