Connection in the future, OIT does not recommend using this ability, but rather recommends users connect using the Cisco AnyConnect client. Jun 18, 2019  This applicaiton uses the built-in VPN support in Mac OS X, so it’ll only work with connections you can configure in the Network Settings panel. If you use a third-party VPN client — for example, to connect to an OpenVPN VPN — it won’t help you. But third-party VPN clients.

Many organizations provide VPN access for the end-user in their company with a third-party tool named Cisco VPN client. This doesn’t work on any 64-bit Mac OS.

However, from Mac OS X 10.6, you can use the in-built feature named IPSec VPN ,so you don’t need to look around for any third-party tool. In this case, you might have to decode your .pcf file which contains all the configuration of your VPN setting.

Here’s the step by step guide for configuring it:

1. Open System Preferences -> Network
2. Click “+” to get more options where you have to select Interface “VPN” and VPN Type “Cisco IPSec“. Hereby give your proper description in “Service Name” and click Create

Once you create this, the main work out is to decode the “enc_GroupPwd” which you can’t simply copy and paste.

1. Simply, open .pcf file that you got from your organization in any editor (e.g.: Notepad ++ ), and copy hostname and put it in your server address.
2. Click Authentication Settings, and mention GroupName as per your PCF file. Now you will see enc_GroupPwd in your PCF file which you need to decode and put it in Shared Secret

There are many ways of getting a clear group password. Jenkins. However, I recommend using this link to decode it. Once you manage to set up all the required settings, you can simply press connect.
