Hello, My wife and I each have iPhones and iPads. We have 3 Apple IDs that are used like this: * Family ID for store purchases, calendar, contacts, reminders * Individual IDs for app data, notes, etc. We are looking at going whole-house Apple with an iMac and Air to replace our Windows desktop and laptop. I'd like to confirm that we can use iCloud and share information on the Macs like we are on the devices. * Can we use multiple IDs like this in OSX? * Will we each need our own logins on each Mac? * Does the iCloud account you set in system preferences apply to the entire system or to each user account on the Mac? * For some iCloud elements, like Reminders, on the iDevices we can have a family entry and individual entries show up side-by-side. Is this also possible in OSX? Thanks!
