I just installed Acrobat XI Pro and I'm attempting to sign a PDF. According to the help, I should be able to scan a signature using a webcam, but I don't see that option available to me. My options are: Type my signature, Draw my signature, Use an image, or Use a certificate.
I have a MacBook Air with a built-in camera. I'm running OS X 10.8.4. What am I doing wrong?
