Mac access to CyberGhost VPN has always been available, but only as a premium subscription using VPN protocols such as PPTP and L2TP/IPSec. Using the new client is completely free and doesn’t require any additional configuration. You get AES 256-bit encryption and your traffic isn’t logged. It does have the same limitations as the PC client, however: a three-hour limit and a smaller set of servers (40 vs 227) and countries (16 vs 24).
With the addition of the Mac client, which we somehow missed a couple of weeks ago, CyberGhost VPN now has desktop clients for OS X and Windows. Linux is supported via PPTP, L2TP/IPSec or OpenVPN. There’s also a mobile app for iOS and Android.
