OS X 10.8 Mountain Lion users: Because the Mars24 application is not digitally signed, the Gatekeeper security feature now included in OS X will block you from trying to run Mars24. The error report will state that the application "is damaged and can't be opened." At present, the only way to alleviate this is to lower the security setting in your preferences. Select System Preferences > Security & Privacy & General and set "allow applications downloaded from" to "anywhere".
