Built-in Markup can't number

macOS Markup gives you shapes and text, but no real way to add ordered step markers — you'd have to draw a circle and type a number into each one, then keep them consistent by hand. macshot has a dedicated number tool that does it for you.

Click to count

Pick the number tool and click on the part of the image each step refers to. The first click is 1, the next is 2, and so on — no typing, no manual sequencing. Delete or undo a marker and the rest renumber so the order stays right.

Make them yours

  • Drag any marker to reposition it.
  • Adjust the size and color to match your style.
  • Give a marker a pointer so it clearly indicates what it labels.
  • Set the starting value when a sequence continues across images.

Great for guides and docs

Numbered markers are the fastest way to turn a screenshot into instructions — onboarding docs, bug reports, tutorials, and how-tos. Combine them with arrows, text, and highlights, then copy or save the finished image.

How do I add numbered steps to a screenshot on Mac?

macOS Markup has no numbering tool. macshot adds one — pick the number tool and click where each step goes, and it drops 1, 2, 3 automatically with a clean circular marker each time.

Do the numbers increment automatically?

Yes. Each click places the next number in sequence. If you delete or undo a marker, the count adjusts so the sequence stays correct.

Can I move or restyle the markers?

Yes. Markers are editable annotations — drag them to reposition, change the size and color, and they can point to the thing they label.

Is macshot free?

Yes. macshot is free and open source under the GPLv3 license, with no subscription or account.
