You probably arrived here because of a curt message in response to an issue you filed on a repo that I contribute to. Sorry about that (particularly if you filed the issue long ago and have been waiting patiently for a response). Let me explain:

I work on a lot of different open source projects. I really do like building software that makes other people's lives easier, but it's crazy time-consuming. One of the most time-consuming parts is responding to issues. A lot of OSS maintainers will bend over backwards to try and understand your specific problem and diagnose it, to the point of setting up new test projects, fussing around with different Node versions, reading the documentation for build tools that we don't use, debugging problems in third party dependencies that appear to be involved in the problem... and so on. I've personally spent hundreds of hours of my free time doing these sorts of things to try and help people out, because I want to be a responsible maintainer and I

OpenConnect VPN on Mac OS X

Unfortunately, the Cisco AnyConnect client for Mac conflicts with Pow. And by "conflicts", I mean it causes a grey-screen-of-death kernel panic anytime you connect to the VPN and Pow is installed.

As an alternative, there is OpenConnect, a command-line client for Cisco's AnyConnect SSL VPN.

Here's how to get it set up on Mac OS X:

  1. OpenConnect can be installed via homebrew:

     brew update
    

brew install openconnect
