How to update apple id settings on Mac?
I had issues with a seemingly forgotten password (carefully written down at the last change, but now seemingly invalid), and I changed my Apple ID. I can access Support with the new ID, which seems to have propagated to my iOS devices. On my iMac, the Name, Phone, Email section lists my new Apple ID email, but under my picture is the old Apple ID email, and I am prompted to "Update Apple ID Settings," which references the old Apple ID email and the password. If I indicate a forgotten password, it wants to change my newly entered Apple ID but if I indicate the old, replaced Apple ID that needs updating, the dialog reports that "This Apple ID is not valid or not supported."
How can I clear out the references to my old Apple ID and use the new one without any data loss?
