Hi Simon,
Your shift issue could be related to the firmware of the drone.
You should have a look on this post. Some users have experienced the same issue and Blaž proposed a workaround in the official comment:
Pix4D Mavic 2 Processing Issues
Regarding the satellite map view, It is indeed not possible to have the satellite base map on Mac at the moment.
You can find more information about this and other differences with the Windows version here:
Beta macOS version of Pix4Dmapper 3.0
Hope this will help,
Best,
