I think some of you are a little confused by my post or maybe its me.
The FIX is here in my post its NOT just for Aperture...
1. Open the App called Image Capture (it should be in your applications folder)
2. Once open go to the Pref. (apple , ) and click the general tab
3. You will see an option to open an application when camera is connected
4. Adjust what you need to, or just select No Application.
Hope this helps.
