Nik Collection 4 Interface problem with Photoshop on MacBook Pro

When I apply a Nik plugin to a Photoshop layer, the window that opens appear behind my original image and I am unable to use the Nike window without it being blocked by the original image window. I can select the Nik window and move it, but the original image always blocks my view. If I select the original image layer window, I get the spinning beach ball.
