Notes:

• Catalina MAC OS by default does not allow installation of apps that are not notarized by Apple. It also requires approval by admin for apps to access desktop and documents folder. 
• SSL VPN-Plus Mac Client is notarized by Apple. Verification of notarization is done automatically during installation of the client and should work for most cases. 
• If it fails for some reason (For example: Because of a network connectivity issue), installation would be disallowed with a warning. To continue with the installation, you would need to permit the installation for SSL VPN-Plus Client app in Security & Privacy under System Preferences and allow it to access desktop and documents folder.
