Question: How to split devices into separate accounts
My sister and I share an apple ID account. I have an iphone, macbook, and ipad which are all synced together through icloud. My sister has an iphone and a macbook which are connected to my apple id, and i believe my icloud id as well. My first thought was to make her a new, personal apple id, but then she would lose the music,apps,pictures registered to my apple id. Is there anyway I can create a subaccount that can still access music and apps from my apple id without sharing anything else or should i set her up with a separate icloud account? My main concern is having her lose their contacts, pictures or calendars if I switch them to new iclouds? I really don't have a single clue what to do. Please help.
