Resolution

Here are some things to try to resolve the white screen issue in Respondus Lockdown Browser on a Mac:

  • Ensure that you have downloaded and installed the Lockdown browser from Michigan State's unique download link (this is the link in the quiz): MSU Respondus Download Link
  • Use a different standard browser like Chrome or Firefox to start the exam and launch the secure browser.
  • Power down and restart the computer to clear out subtle corruptions that can build from constant use of Sleep Mode.
  • Disable or remove any third-party security apps and verify the MacOS is up-to-date with all the security updates.
