In the past i had CamTwist installed on my macbook Pro, and i believe it is what installed the Soundflower aggregate devices to my mac. However, I don't use CamTwist anymore, and when i uninstalled it, the soundflower virtual devices remained under the audio devices in /Applications/Utilities/Audio MIDI Setup.app. I can't find a solution to removing them anywhere, and it won't let me simply remove them with the (-) symbol at the bottom of the application. Any solutions? Thanks so much! I appreciate it!
