Security Certificate Installation on macOS
Please note: The certificate must be installed from
a user account with Administrator privileges.
Using the Safari browser, tap the shield below to download the installer.
Right-click the file icon and select Open from the shortcut menu. You
will receive a security prompt asking you to confirm opening the file. Click
Open to launch the program.
A terminal window will open, asking for the login password of your user account.
Enter your password
(the terminal window will not show the characters as you type)
and press the return key on your keyboard.
You should see a Success! message indicating certificate installation
was successful. The terminal window can now be closed.
