Troubleshooting
Resolve permission, clipboard, protected content, and display issues.
Permission not showing
Open ShutterDock once, start a capture, then return to System Settings > Privacy & Security > Screen & System Audio Recording.
Clipboard did not update
Try a second capture and confirm the destination app accepts image paste from the clipboard.
Black screenshot
Some protected video, banking, or DRM surfaces intentionally block capture at the system level.
External display issue
Reconnect the display, check macOS display arrangement, and try capturing a smaller region on the affected display.
