By default, Safari 6.1 and later play rich-media content in Safe Mode. Safe Mode protects the user by restricting what can be done with content that you create in Adobe Flash. But, it also prevents some content from working correctly, such as installing AIR applications or Adobe connect.
If you trust the current domain, you can use the following steps to enable the content to run in Unsafe Mode. Unsafe mode places fewer restrictions on content so the content can work correctly.
