My Mac says kakemono “is damaged and can’t be opened”

Section titled “My Mac says kakemono “is damaged and can’t be opened””

It isn’t damaged. macOS says this about apps that aren’t signed with a paid Apple certificate. Install on a Mac shows the one command that fixes it. You only run it once.

Windows says “Windows protected your PC”

Click More info, then Run anyway. Windows says this because kakemono isn’t signed with a paid certificate yet.

  • Mac with a notch: macOS hides menu bar icons that don’t fit next to the notch. Quit a few other menu bar apps, or use a menu bar manager such as Ice or Bartender.
  • Windows: click the ^ arrow next to the clock. The icon may be hidden there.
  • Linux on GNOME: install the AppIndicator extension. Other desktops show tray icons without it.

That’s the default. kakemono changes the wallpaper only when you click Next or choose one in the picker. To change it on a timer, tick Change wallpaper every in Settings. See How to use kakemono.

macOS doesn’t let apps set the wallpaper of every Space at once. kakemono sets it on the Space you’re looking at. Spaces on macOS has a setting that updates each Space when you switch to it.

Hover over Invalid in Settings to see why. The usual causes:

  • An Unsplash source without a key. See Unsplash needs a key.
  • A web page that kakemono can’t read, such as Pinterest or Instagram.
  • A link from a site that the source doesn’t accept. For example, a Reddit link in a Wallhaven source.

Run kakemono doctor in a terminal. It says which wallpaper tool kakemono uses for your desktop and what went wrong. Linux desktops explains the fixes.

Troubleshooting covers more problems. If yours isn’t there, open an issue on GitHub and say which system you use.
