Grabber is not a verified Apple application, so you might get a "the developer cannot be verified" error. In that case, you should open Finder, go to your Applications directory, then right click then choose "Open". Then, you'll be able to choose "Open" to start Grabber anyway. You only need to do this once. More information here.
