Thanks a lot James.. Viscosity 1.4.11b18 fixed my problems. 
HMAC problem is fixed! IPv6 still fails though; is there anything I can provide to help? It does work manually but otherwise it fails on two different Yosemite DP4 installs.
The latest build/release worked for me! You’re awesome James.
Oh.. I overlooked this.. without changing anything at the VPN Settings to my company, Viscosity is not connecting anymore.

b18 seems unable to use my SSL certificate (which is present in the connection details and used to work in earlier versions):

same issue here for b18. Tried rolling back to b17 just to see what happened, and it’s a no-go too (can’t find a tmp file).
b14 is working for my SSL-based VPN, it’s broken since b16 (haven’t tried b15).

If you receive an error message stating that Viscosity’s helper tool was unable to be installed/updated under Yosemite please restart your computer or uninstall the old helper tool like so:
sudo launchctl unload /Library/LaunchDaemons/com.sparklabs.ViscosityHelper.plist
sudo rm /Library/PrivilegedHelperTools/com.sparklabs.ViscosityHelper
sudo rm /Library/LaunchDaemons/com.sparklabs.ViscosityHelper.plist

With b19 unfortunately still no connection

Hi DJay,
That doesn’t look directly related to the beta version: I’d recommend you try restarting your computer and ensure no other VPN clients are running at the same time. An adapter number of 155 means you either have a lot of stuck connections or another application is interfering with Viscosity’s TUN/TAP drivers.
Cheers,
James
We haven’t taken a close look at IPv6 under Yosemite as of yet, however it should be something we get around to soon.
Cheers,
James
Thanks James.
Unfortunately restart didn’t help.
And there is no other VPN connection running. 
Fixed it. Sorry for the confusion. 
Don’t know why but the information about the Routing was lost.
So I had to type in the list again.. Destination, Mask/Bits, Gateway… but now everything works as expected.
Thanks James for your superb support and work.
Awesome, thank you James!
Thanks James! b19 connects and works well so far! 
Cheers.
Hi, I’m also having an issue with connecting via the latests build (1.4.11b19).
Viscosity hangs while attempting to connect, and loops over the follow log message:

What I’ve tried:
- various versions of Viscosity
- removing old config files / versions of Viscosity
- reloading client.opvn
- restarting the computer
- toggling IPv6
- verifying that the ViscosityHelper is running
Any ideas, thoughts?
Thanks in advance.
Hi,
I am a early beta tester for osx yosemite and am running the new version of viscosity, however once I try to connect I seem to be getting a can’t allocate memory error yet I am sure I have enough, when in fact the helper is taking 2g of ram. Can anyone help me with this problem?.
I posted the log below

First, thanks for your amazing software.
Since I’ve switch to Yosemite, Viscosity (Stable or Beta) doesn’t seem to play well with PKCS11/OpenSC anymore, it use to work fine in Mavericks.
Here is the log of an attempt of connection with a PKCS11 Smartcard.

Getting this in my console, and the menu item is not showing so I cannot connect:
