The trick of going to the Security System Preference didn't work, since there is no button to trust Oracle. Is there any other way to tell the Mac to load those extensions?
And, since I don't remember having changed anything in my system (apart for the usual cleaning with Cocktail), does this reveal some other type of issue?
