Hi all -  
Newbie here.  Updated firmware and O/S.  Using Macbook Pro Retina.  Downloaded DJ assistant.  Updated firmware.  After all the charging (2 battery failures btw).  I attempted first beginner flight.  Controller reported calibration requuired.   Went back, checked the lens were not covered/dirty.  

Attempted to calibrate on 2 monitor setup.  No go.  Researched a bit.  Seems this is a common issue.   Removed the second display.  Got to 85% complete several times after using the process.   Tried several different USB cables and connections.  Changed the displaying scaling to 1280, 1600, 2048, etc same issue 85% and no further.    Rebooted drone, PC and app.  What could be going on?  Assume there are a lot of Macbook users here.

thanks for your help.  Figure I deifintely need these given my green status.

Tried again this morning.  Again the process stalls on 85%.   The drone motor fan runs like crazy when it gets to this point.   Please help!

Ok, stand down....figured out to do it from the remote/phone.  All is good.
