VPN Tracker 6 won't work on Mac OS X Yosemite
As read here, Yosemite won't load kernel extensions that aren't signed by an authorized kext (kernel extension) developer (at this stage, the protectionism of Apple no longer astonishes me).

The workaround is to turn your OS X into a kernel extension developer mode by adding this to the nvram parameters:

sudo nvram boot-args="kext-dev-mode=1"


After rebooting, VPN Tracker 6 launched and connected trouble-free.



@Equinux and their greedy licensing policy: I am so very glad that you did not get my €€€. Your message "VPN Tracker 6 is out–of-date" with either Quit or Upgrade to version 8 shows how much your company is run by dinosaurs still stuck in the 90s of Microsoft of sorts.
