I'm just starting the exciting journey into plugin development using JUCE and already I've hit a problem! I am simply trying to use the juce demo plugin in a plugin host. I'm on OSX 10.7.5 and I copied the .JuceDemoPlugin.component plugin from .../JUCE-master/extras/audio plugin demo/Builds/MacOSX/build/Debug into my /Library/Audio/Plug-Ins/Components folder. However when I open Ableton Live 8, Logic Pro 9 or AU Lab I can't see this plugin even after a computer restart. Can anyone suggest what I might be doing wrong?
