Anyone know why this software does not upload on Mac. It acts like it's installing but it just stalls and then won't quit and I just have to turn my computer off and restart it. I'm running OS High Sierra v 10.13.1. It appears the last update to the software was in 2015 and doesn't support my OS version. Is this correct and if so, what are the alternatives to get my photos from camera to computer? I am very new to the camera and somewhat techie but this is above my level.
