Mac OS X 10.8 (Mountain Lion) introduced a new feature called GateKeeper, which can prevent software from installing if it has not been digitally signed for the OS. Older versions of MakeMusic notation products and Garritan libraries were released previous to this change, and have not been digitally signed. Please find your operating system below and follow the appropriate instructions.
