Download Plug In For Mac

Safari no longer supports most web plug-ins. To load webpages more quickly, save energy, and strengthen security, Safari is optimized for content that uses the HTML5 web standard, which doesn't require a plug-in. To enhance and customize your browsing experience, use Safari extensions instead of web plug-ins.
