Hi everybody
Some time ago, I changed my Apple ID, switching to a Gmail email account.
I was able to change my Apple account settings without any problems on both my iPhone 13 and a MacBook Pro (10.13.6).
However, on a slightly older (...) iMac, El Capitan 10.11.6, the same operation is impossible because: 1-It asks me to enter the password associated with the old Yahoo ID, which no longer exists, and 2-When I go to Settings > iCloud, the "Account Details" button is grayed out, so I'm unable to make the necessary changes.
How, if possible, can I fix this problem?
Thanks for the help
