Question : Problem: Can I use the Mac Built In Cam on WinXP/Fusion?

I just want to know if I have to plug in a whole 'nother web cam just so my seed of XP Pro can use it or if there is a way I can use the built in webcam on my MacBook Air?

It should work fine if you install through Bootcamp.

As for Fusion, you may need to install the driver here (http://www.stevienova.com/Drivers/iSight.zip)
To use the driver package, extract the folder inside of it to the desktop and go to Control Panel > System > Hardware > Device Manager. Then on the device with the yellow question mark, right click and click Update Drivers. Select "Install from a list or specific location (Advanced)" then "Don't search. I will choose the driver to install" Then click "Have Disk" and navigate to the desktop folder where the driver is. Click OK and Continue Anyway if it comes up.
