I have no idea if I'm posting in the right spot, but here goes. I just signed up for a Skype account, but don't know if my computer has a microphone. How can I find that out? I did a search on the hard drive but didn't come up with any microphone. Do I need to purchase one? I am working on a 2009 imac.
Carolyn - you will need to select the microphone in Skype Preferences>Audio (if it doesn't happen to have defaulted to that). There is a setting for input in System Preferences>Sound but it doesn't apply to Skype.
