Hi Gang - I just received my new P4 yesterday. After going though all the tutorials and charging up the bird and the controller, and installing DJI GO on my device, I fired up and I got an alert in DJI GO saying "RC Update Required". I downloaded DJI Assistant for Mac, logged in and wired up the P4 to my Mac. There were 2 updates available and I chose the newest of the 2. It downloaded, but the update failed to be installed. DJI assistant told me to reboot the P4 before clicking retry. I did. It failed again. I then tried to update the other firmware that was available. Same results. Are all updates done with the P4 connected to the MAC or should it be done with the controller connected? Please help...I'm anxious to get off the ground in beginner mode.
