I can connect to my work laptop through a VPN service that the company has set up. Thankfully, it supports Macs.
Since upgrading to OS X 10.6 (Snow Leopard) I noticed that my Network Connect did not work. It would always return an error saying that it couldn’t establish a secure connection. After some digging, I found an article with some simple commands that did the trick!
Type the following two lines into a terminal window:
sudo chmod 755 /usr/local/juniper/nc/[version number]/
sudo mkdir ‘/Applications/Network Connect.app/Contents/Frameworks’
I have version 6.4.0 and it worked for me. Apparently it worked for other older versions as well. One thing to note is that if the software is ever upgraded (i.e. if you notice that new software is being upgraded in your system when running Network Connect), then you’ll need to run these same steps again.
