I upgraded all my software and turned on iCloud on my iPhone and my MacBook Air. When I turn on iCloud in the address book, it duplicates my contacts list. The "On My Mac" Local set of contacts does NOT update and I can't seem to turn off these contacts. The iCloud functions work because when I edit an entry on my phone it updates. Is there a way to have only the iCloud contacts visible and updating between my different Macs and iPhone? Thanks!
