On one of my Macs the contacts are duplicated
On my iMac the Address Book shows two accounts (Mac & iCloud). Thus the contacts are duplcated. On my other Mac (MBP) there is only one account and that is iCloud. Thus the contacts are not duplciated. I assume that the contacts on the MBP are never resident on the Mac, but stay in the cloud. How do I get rid of the duplcates on my iMac? There does not seem to be any way I can click off the local file (Mac).
