Lost Head Tracking on Unity 2017.1

Hello. I have the old Oculus DK1, still working until yesterday, that i was on Unity 5.5.0f3. Was perfecto, to the limits of DK1. Head tracking etc.
But today i decide to put the lates update (besides de beta, that i prefer not), Unity 2017.1
And then, head tracking stop working. But i can see it try to turn the camera, but the camera follows again to the center of view. I can only turn with mouse now.
I use it on El Capitan, on an iMac machine. IS not fast enough, but optimizing the scene i can have 30 fps or more.
I already try to reinstall over the sdk from Unity Store, without luck.
My Oculus is using Oculus Configuration Utility 1.6 (SDK 0.5.0.1)
So, anyone can held to solve this problem, or i will need to go back to 5.5.0f3?

Thank you anyway!
Cheers!
