To install the Kerio VPN Client, use a corresponding package with the .dmg extension (e.g. kerio-control-vpnclient-1.2.3-4567-mac.dmg). The package will be mounted as a disk. From the mounted drive, run the Kerio VPN Client Installer. Standard wizard is used for the installation.

The Kerio VPN Client is installed as a System Preferences panel. In the system, the installation creates the kvnet0 virtual network adapter and the Kerio VPN Client Service system service (kvpncsvc) which is run upon completion of the installation and is then initialized upon each startup of the operating system.
