Annotate images
If you add an image to your document, you can use Markup to add shapes, text, and callouts to it within TextEdit. You can even draw on your image using your trackpad.
Move your pointer over an image, click the Markup pop-up menu , then choose Markup.
If you don’t see the pop-up menu, you may need to enable Markup. Choose Apple menu > System Preferences, click Extensions, click Actions, then select the Markup checkbox.
Use the tools in the toolbar to mark up the image (or use the Touch Bar).
Sketch

If your drawing is recognized as a standard shape, it’s replaced by that shape; to use your drawing instead, choose it from the palette that’s shown.
Draw
Draw a shape using a single stroke. Press your finger more firmly on the trackpad to draw with a heavier, darker line.
This tool appears only on computers with a Force Touch trackpad.

To create a new signature:

If your trackpad supports it, press your finger more firmly on the trackpad to sign with a heavier, darker line.
Using your computer’s built-in camera: Click 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.
