    Mountain Lion Support

    Currently, none of the Mac OS X applications are signed. To run them on Mac OS X 10.8 (Mountain Lion), you would have to enable the option to "Allow applications downloaded from: Anywhere" in the General pane of the Security & Privacy options within the System Preferences. Or at least, you would have to enable that option temporarily for your first launch of the applications; then you can change it back to its previous setting.

    Note, however, that TrashLater Server does not interfere with GateKeeper since it runs as a "launchd" background process. It therefore continues to work just fine even for Mountain Lion.
