iCloud Opt-in-out
I upgraded to 10.9.x and found that I was irrevocably married to iCloud for my Contacts. I did _not_ opt-in to share my Contacts on Apple servers (although the language is, no doubt, buried in the licensing agreement somewhere). Now I now find my Music has somehow migrated to iCloud. I am being peppered with "updates" to add more processing requirements to my already over-worked chip. However, I am reluctant to upgrade anything for fear I will end up with my "whole life" on iCloud.
Questions:
1. Is there anyway to opt-out of iCloud and get all instances of my data back?
2. I am told that once I upgraded to 10.9.x I could never go back to an earlier version of IOS. Is this true?
Thanks for any help.
