I regularly use the Lync web app for Safari & Chrome on a Mac as my clients use Skype for Business. This used to work fine, but recently it keeps asking me to download and install the plugin. However, even after I've installed the plugin, the web app still tells me that I need to install the plugin. Jun 23, 2017 Similar Software 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.
