Ramifications of separate Apple IDs
My iMac runs OSX Mavericks and my wife's runs OSX Mountain Lion. We also each have an iPhone and iPad. We have always used the same Apple ID but this causes some confusion. For example: In Contacts, when I mark my card as "me" it also makes that designation in her Contacts, which leads to problems with calendar notifications and, I think, in email. We are thinking that it would be better if we each had our own Apple ID. I wonder if anyone could summarize what ramifications this would have to the way we use the computers and what things might change. Also, would we each have to get a new Apple ID or could one of us keep the current one and simply change the ID on the second computer? How would we go about doing that? Thanks!
