Igor using advanced graphics unit on MacOS all the time


can anyone confirm: Igor (8.03B01, running on a MacBook Pro14,3, MacOS X 10.14.3 ) is using the advanced graphics unit all the time?!

Is it necessary to make Igor doing this (thinking about battery consumption)? Is there a workaround to make Igor using the Intel Graphics? Some 2D graphs are not that complex - maybe switching to the advanced graphics is necessary when using 3D gizmos? A dynamic switching would be nice.
