Typical extension for Safari, but not obvious how to enable it for users who arent tech savvy. Biggest thing, though... why is this dumb extension asking for access to ALL my websites and history? Go into your Safari content settings and make sure it's set to DENY for everything except Classlink. Classlink, maybe just modernize your website to work without a stupid extension?

Be sure to open your preferences in safari and click a check box to enable the extension. Just to click "open" on the app store and get a little un-closable pop-up telling you about ClassLink isn't needed. We are all here on the app store extension page because we tried to open ClassLink and it told us we needed this extension. Sure, have a pop-up window when you click open. but the first piece of info that pop-up should have is: in the Safari menu bar, click "Safari" > "Preferences..." Click on the "Extensions" tab and enable ClassLink LaunchPad Extension by clicking the box beside it's icon in the list of extensions.

This app does work you just have to enable it in your prefrences with safari. When your safari window is open at the top on the menu bar click on "Safari" go to "Prefrences" > click on the "Extensions" tab and click the box in the left box.

People should be FIRED for this. And not a few people, lots of people. Any organization that chose to use ClassLink should fire the people who made that decision.Had to install this to log into my kid's school work on the family MAC. Fine. Installed it and it does nothing. Launch the app and all it does is show a window with a sales pitch on how easy it is to use. Spend an hour screwing around before stumbling upon these reviews that told me how to enable the extension in Safari.
