The easiest way to use Inline Grading for assignments is to use Chrome or Firefox, which work without modification.  If you still want to use Safari, follow the instructions below.

To change this setting, choose Preferences from the Safari menu.

Safari Preferences

Then, choose Privacy.

Safari Preferences Privacy

On Sierra and earlier, choose Always allow from the “Cookies and website data” menu.

Safari Preferences Cookies Website Data

On High Sierra, uncheck “Prevent cross-site tracking”.

Safari Prevent Cross Site Tracking

Quit entirely out of Safari, and when you get back in, inline grading should work properly.
