Change Apple ID to new iCloud address?
When I set up AppleID years ago, I used an existing 3rd party email address instead of letting it set up an iCloud email, so I don't have an iCloud email address. That is now causing me problems with Apple Mail accounts that I won't go into here. But I am pretty sure the solution is to set up a "new" iCloud mail account [I'll be using my iMac], change the Apple ID to that email address, and then change over the AppleID on my other devices. I have these questions about the process.
- I read online how to initiate the setup of the iCloud mail account using System Preferences / iCloud on the iMac and clicking on Mail, which currently is NOT checked. That makes sense; I can do that.
- Does that automatically change & link my AppleID account on the iMac to that new address, or do I have to do something?
- Then change the Apple ID on my other devices?
- Do I have to log out of the current AppleID before doing the above steps on the various devices?
Thanks for any help.
iMac, macOS 10.13
