info: [ForceQuitUnresponsiveApps] 2013-12-10 15:11:16.424 ForceQuitUnresponsiveApps[56799:507] Force quit unresponsive instruments v0.0.1
info: [ForceQuitUnresponsiveApps] 2013-12-10 15:11:42.708 ForceQuitUnresponsiveApps[56799:507] Force quitting: 'freeze2' at 'file:///Users/user/ForceQuitUnresponsiveApps/freeze2/./bin/freeze2.app/Contents/MacOS/instruments'
