This section explains the scenario using the following case as an example.

• OS: macOS version 10.13.3
• Web browser: Safari 11.0.3

1. Start your Safari.
2. From the "Safari" menu, select "Preferences".
3. Select "Privacy" and click Manage Website Data.
4. Select cookies or cache to clear, and then click Remove.
   If you want to clear everything, click Remove All.
5. Check that the Website data you selected in step 4 is cleared, and then click Done.
6. Click x to close the "Preferences" dialog box.
