you can't logitech is only supported on windows
All Apple computers except the Mini Mac & Mac Pro have a built in Webcam. Logitech builds webcams that are Mac compatible. Just make sure the one you buy is.
The Logitech Dual Action pads only work on PC's, unfortunately. Consider getting Parallels for Mac so you can use Windows.
Although I have a webcam already attached to my computer I've heard that Logitech webcams are great in quality and work very well. They seem to be the biggest and best webcam company out there.
In Jan 2012, I bought Logitech Webcam C110, and tried so many times with many tricks I read fr the net to use with XP SP3 and SP2, ... but it can't work! in the device manager : the USB video/audio device si still with the "yellow" mark. Even lws230_full.exe driver that I downldd fr logitech webst said : this software is NOT COMPATIBLE with the cam! this is really strange ...... already tired .... maybe it's time to move to Windows7.
WORK A WEBCAM? WORK A WEBCAM?
Apple Macs come with a built-in iSight web cam but many other web cams can also be used. Those that do not provide official support will often work with a Mac using software such as MacCam (See links below).
Open a webcam program and it should work.
go to cam/rec and click webcam
download ManyCam Virtual Webcam 2.4.39
Without a webcam you can only edit it.
