How do I fix this?
I have had this issue since we went from Me.com to iCloud.com with having 100's of duplicates of the same GROUP in my contacts via my iCloud.com account; which is my main iCloud account. I had created a secondary @me.com account that I use only for my Contacts and junk email (this was created at the same time as the iCloud.com transition).
1.I have ran an Apple Script trying to delete these duplicates.
2. I have spent hours on iCloud.com deleting this group. When I do this the screen will get darker and darker while I am hitting Delete then Enter to confirm the deletion. After a period of time the screen will return to normal and I will continue and the screen goes black again..
3. I have tried deleting any files that I know of that are associated to my Contacts on my MacBook; is there another file or library that I can delete that might "Reset" this icloud account?
