When we switch over to a new Moodle site for the next semester, here is how to flush my DNS cache so that 'moodle.ovs.org' redirects to the correct copy of Moodle:

  • Go to Applications -> Utilities -> Terminal

  • Type the following command and press Enter:

dscacheutil -flushcache
  • After that type the second command and press Enter:

sudo killall -HUP mDNSResponder
