I run double laptops simultaneously to better monitor users and chats, so I can choose between the webcam on my MacBook Pro and my Toshiba Portégé. As such, I know which webcam does a clearly better job.
Better than social media, a Canon Support representative has said he understands a Mac version is under development -- posting #85 on this page:
A number of people have mentioned they've downloaded the version for <name a camera model>, but isn't it, in fact, the same software irrespective of which camera you're going to use?
It'd be a pretty horrible solution if you had to use particular versions for each model of camera you might connect!
Really sour way to kick off a topic discussion. Yes, Canon has been properly shamed by your scolding.
