I am so confused. I consider myself fairly tech savvy. I have an iPhone 6, iPad Air and a PC. I just bought a gold MacBook for my granddaughter for Christmas. I am trying to help her figure out how best to set up the iPhone in Settings>Photos & Camera. She has the Mac set up now so that "all my pictures are there!" But then she noticed that if she deleted a photo from the phone (to clear up some storage space), it also deleted it from the iCloud Photo Library on her Mac. I would like to help her so that it automatically saves her photos to her iCloud Photo Library on her Mac (I'm not even sure if that's what it's called), and yet allow her to delete photos from her iPhone without deleting them from her Mac. Surely this is possible? In settings, should these things be off or on? iCloud Photo Library, Optimize iPhone Storage, Upload to My Photo Stream. And once we get that taken care of, she hopes to be able to leave on "iCloud Photo Sharing," because she's pretty excited about that. I have read the support materials, and I simply cannot figure this out. I hope someone will take pity on this Mamo and help me know what to do to help her!
