Starting on March 1, 2018, a pop up on my iMac has been asking me to sign in to iCloud. When I do, it doesn't accept my password, and asks if I want to change it. I've changed it, and it still doesn't accept it, although my other devices do. Does anyone else have this problem?
When you get the request to sign in, are you already signed in?
What to do after you change your Apple ID or password - Apple Support
Go to Finder and select your user/home folder. With that Finder window as the front window, either select Finder/View/Show View options or go command - J. When the View options opens, check ’Show Library Folder’. That should make your user library folder visible in your user/home folder. Select Library. Move the following to the Trash and restart.
Close all running apps. Put the following items in the trash:
1) In the ~/Library/ folder, put the Caches folder in the trash.
2) In the ~/Library/Application Support/ folder, put the folder iCloud in the trash.
3) In the ~/Library/Preferences/ folder, put the file MobileMeAccounts.plist in the trash.
