OpenVPN on Intel OS X

So for those of you with Intel Macs and want to use OpenVPN I’ve found a couple things to get you going. At the moment the TunnelBlick setup doesn’t really work with Intel OS X. You need to get tun/tap drivers that are built for Intel OS X.

I found the following pre-built drivers, the installer is broken how it is possible to manually install the drivers by copying the Archive.pax.gz file out of the Package directory structure from the terminal and then extract the contents using Finder. Once extracted find in the directories created tun.kext or tap.kext depending on which Package your working on. After that you copy the extensions for the tun/tap drivers into the /Library/Extensions directory, tun driver is ‘tun.kext’ and the tap driver is ‘tap.kext’. Once you’ve copied both ‘tun.kext’ and ‘tap.kext’ from the respective packages into the /Library/Extensions you need to run the following commands:

cd /Library/Extensions
sudo chown -R root:wheel tun.kext
sudo chmod -R go-w tun.kext
sudo chown -R root:wheel tap.kext
sudo chmod -R go-w tap.kext

Then in the startup_item package if you again copy the Archive.pax.gz file out of the Package directory and then decompress with Finder. Once decompressed find the StartupItems directory in the extracted directories and copy the contents of StartupItems to /System/Library/StartupItems.

Then grab the latest RC of TunnelBlick 3 from the TunnelBlick site and drop it into /Applications and you should be good to go.
