I have a @mac.com Apple ID. How can I sign is using @icloud.com?
Currently my Apple ID is ***@mac.com When I try to sign in to iCloud using any address other than the @mac.com, I get error saying password doesn't match. I thought they were all the same??? Someone is using my @iCloud address at Walmart and I don't know what I need to do to protect myself. Is it possible for someone else to create an Apple ID using my @icloud.com address? If I change my password for the @mac.com address, will that offer any protection? If I change my Apple ID to ***@icloud.com will I still receive emails address to ***@mac.com and ***@me.com?
