macOS 26+ · Apple Silicon / Universal (Apple Silicon + Intel)
Open the DMG, drag PurePin to Applications, and open it from there. For a release marked not notarized, macOS may block the first launch. After attempting to open PurePin, go to System Settings → Privacy & Security, find the message about PurePin near the bottom, and choose Open Anyway. Confirm the system prompt. See Apple's instructions.
On first launch, PurePin shows screen capture setup if permission is missing. Choose Allow Screen Recording and finish the macOS prompt. If needed, Open System Settings takes you to Privacy & Security → Screen & System Audio Recording. Enable PurePin; quit and reopen it if macOS asks. Once setup says you're ready, choose Done, then press F1 yourself. Setup does not start or queue a screenshot.
PurePin uses this permission for still screenshots. It does not record audio or require Accessibility, Camera, or Microphone access.
| Action | Default shortcut |
|---|---|
| Start a capture | F1 |
| Edit an image from the clipboard | ⌥ + F1 |
| Pin an image from the clipboard | F3 |
| Hide / restore all pins | ⇧ + F3 |
| Copy the capture and finish editing | Return or ⌘ + C |
| Pin the current capture | ⌘ + T |
| Save a PNG | ⌘ + S |
| Undo / redo | ⌘ + Z / ⇧ + ⌘ + Z |
If macOS uses the function keys for system controls, hold fn / Globe or choose another shortcut in Settings.
To annotate an existing image, copy the image itself and choose Edit Clipboard Image from the menu bar. Zooming and panning only change the view; copying, saving, and pinning preserve the original pixel dimensions unless you crop the image. Cropping changes the output area and dimensions. Clipboard editing does not require screen recording permission.
Drag a pin to move it, scroll to resize it, and double-click to close it. Right-click to copy, save, or restore its original size.
