Safari on MacOS and iOS handles cookies differently than other web browsers. When clicking on "My Media" or "Media Gallery" in Canvas in your Safari browser, you may see an error indicating "It seems your browser is blocking 3rd party session cookies which are required for the Kaltura application."


Note: After modifying your Safari settings as documented below, if you navigate away from the page in question (ie. "Media Gallery" or "My Media") and then return, you'll find that the error no longer appears.
