Be sure to install any available updates for the application and Mac OS X.
(I have version 10.6.8) You may need to reinstall the application. It downloaded perfectly, but when I opened the Application, a ERROR screen popped up! (Not the same as the other times though)Ĭheck with the developer to make sure ygopro works with this version of Mac OS X. What a surprise! I downloaded this version too.
