Just a heads up in case anyone is using Apple Remote Desktop to manage mac hardware. The latest upgrade 3.9 has caused some clients to pop up a password request box asking 'ARDagent wants to use the "PrivateKeyStore-50x" keychain'. No matter which password you enter, it keeps returning, and you cannot quit it.
Only way to get rid of it is to Force Quit the ARDagent process, either through Activity Monitor or by opening terminal and typing:-
sudo /System/Library/CoreServices/RemoteManagement/ARDAgent.app/Contents/Resources/kickstart -restart -agent
Have yet to have to repeat this, so it looks like it might be a one-off fix.
