Judging by my testing and comments in the review section, it apparently does work with a wider range of Logitech HD web cameras besides the short-list of officially supported models. If you're running OSX 10.7+ and own more recent Logitech HD camera models, you can download a free Mac Logitech webcam settings software camera app for image adjustment functions in any video capable Mac OSX app. You'll have to go to Logitech's Support pages, identify your product and look for available downloads on a model-by-model specific basis. NOTE: Logitech has removed it's Webcam Settings app from the Apple App Store. That said, it costs nothing to download the Mac Logitech Camera Settings or it's new live streaming Capture webcam software app, install it, plug in your Logitech camera and give it a try to see if your particular Mac and camera model works with it. Some may quit or pop up an incompatibility alert if the proper hardware is not detected. Developers are able to code their apps to poll for the presence of specific USB devices by VENDOR ID: and Product ID: codes as the app launches.
Like many apps written by vendors for their own hardware, the Logitech Camera Settings webcam software for Mac is 'offically' only for specific HD camera models. Logitech Webcam Control Software For MacOS
