Hi  All      anyone  had any problems  with calibration  assitant 2  on an imac?      on the camara caribration  screen ive got no  square  image     to line up with!

Yes I am having a similar issue...it is intermittent but has prevented me from completing the vision sensor calibration. Even when I get through all the square chasing the calculation at the end freezes at 90%. I am using the latest Assistant v.1.2 a p4p and a mac mini running El Capitan. Any pointer appreciated as I wasted 8 hours today trying to sort it out.

JKW try changing your screen resolution

tried  it sir all the resolutions . still no joy    ill keep battling with it  
many thanks John

I only had success doing the vision sensor calibration when I dropped the resolution down to 1920x whatever it is   from 4K.
Even then it was flakey. I am on windows 10 and its marginal on that too. I dont think its an OS thing.
It took a few attempts.
