Master Mac Screen Shot Annotation Tools

Mac has some of the best built-in image markup tools in the world. You don’t need third-party apps to explain your screenshots.

1. The Markup Toolbar

After taking a screenshot, click the floating thumbnail (or spacebar a file on your desktop) and click the Pen icon.

2. Essential Tools

• Shapes: Click the Square/Circle icon. Pro Tip: Use the “Loupe” (magnifying glass) to highlight a specific detail.
• Text: Click the ‘T’ to add comments.
• Signature: You can use your trackpad to write your signature and drop it onto a document screenshot.

3. Highlighting

Select the highlighter tool from the brush menu. It’s pressure-sensitive on newer MacBook trackpads, allowing you to control the thickness of the line.
