Q: (Safari) How do I stop my browser from downloading instead of displaying the Sylantro interface when I go to Sylantro.mit.edu?
Click on the "Safari" menu item in the upper left section of the menu bar and choose "Preferences" from the drop-down menu.
Click "Security" at the top of the "Preferences" window, then click the "Plug-in Settings" button in the lower right.
Make sure there is a check next to "Adobe Flash Player" in the sidebar of the "Plug-in Settings" window, then click the dropdown menu next to "When visiting other websites" in the lower right and select "On".
If "Adobe Flash Player" is not listed, got to this link https://get.adobe.com/flashplayer/ and download "Adobe Flash Player".
