Use Markup to write or draw on a photo in Photos on Mac

In the Photos app on your Mac, double-click a photo, then click Edit in the toolbar.

Click the Extensions button , then choose Markup.

Use the tools that appear in the toolbar to mark up the photo.

To adjust a markup, move the pointer near the edges, then drag the blue handles.

• Sketch : Sketch a shape using a single stroke. 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.)

• Shapes : Click a shape, line, or arrow, then drag it where you want. To resize the shape, use the blue handles. If it has green handles, use them to alter the shape.

• Highlight : Click the Shapes button, then click the Highlight button. Drag the highlight where you want. To resize it, use the blue handles.

• Enlarge : Click the Shapes button, then click the Loupe button. Drag the loupe to the area you want to magnify. To increase or decrease the magnification, drag the green handle; drag the blue handle to change the loupe size. You can place multiple loupes on a photo to magnify specific areas.

  Tip: To further magnify an area, create another loupe (press and hold the Option key while you drag an existing one), then position it over the other loupe, using the alignment guides to adjust its position.

• Text : Click the Text button, type your text, then drag the text box where you want.

• Rotate Left  : Click the Rotate Left button to rotate the photo to the left. Continue clicking to keep rotating. To rotate the item to the right, press and hold the Option key, then click the Rotate Right button until you’re done rotating the item.

• Crop : Drag the corner handles until just the area you want to keep is shown within the frame’s border. You can also drag the frame to reposition it. When you’re ready, click Crop.

• Highlight Selection : Highlight selected text.

• Annotate : Annotate the item by sketching or drawing on it using your nearby iPhone or iPad. The Annotate button appears blue when your device is connected; to disconnect your device, click the button again.

  Your devices must meet Continuity system requirements. See the Apple Support article System requirements for Continuity on Mac, iPhone, iPad, iPod touch, and Apple Watch.
