Same as everyone else
I have the same issues as loads of other people, the app finds the camera and does everything other than Live View. So, I installed it on another Mac I have and Live view works! What im guessing is that this is some kind of Video Card graphics software glitch, its not able to support all the different video cards that Apple has included in all the various Macs that can run this software. The computer that does work is a mid-2008 Mac Pro tower running 10.8, the one that does not is a 27” iMac from 2011 running 10.8 as well.
Logitech needs to have more Mac beta testers IMO.
