Support
Write to support@stillbyte.dev. Tell us your Mac model, the macOS version and the SimpleShot version (SimpleShot › Settings › About).
Installing
Download SimpleShot, open the disk image and drag SimpleShot to Applications. Open SimpleShot from Applications; it lives in the menu bar.
Captures are black or show only the wallpaper
SimpleShot needs the Screen Recording permission. Open System Settings › Privacy & Security › Screen & System Audio Recording and turn on SimpleShot. If macOS asks to quit and reopen SimpleShot, do it.
A shortcut does nothing
Another app may use the same keys. Choose different keys in SimpleShot › Settings › Shortcuts. To use ⇧⌘4 and the other system keys for SimpleShot, first turn them off in System Settings › Keyboard › Keyboard Shortcuts › Screenshots.
Keystrokes don't show in a recording
Showing keystrokes needs the Accessibility permission: System Settings › Privacy & Security › Accessibility, turn on SimpleShot, then record again.
Where are my captures?
Every capture is in the history (⌥⇧⌘H). Saved files go to the folder in SimpleShot › Settings › General (the Desktop unless you change it).
Uninstalling
Quit SimpleShot from its menu, drag it from Applications to the Trash, and delete ~/Library/Application Support/SimpleShot to remove the history.
