Ghost Icloud Account in Internet Prefrences
I tried valiantly to correct this problem for over a 3 months and I can't figure it out. In my internet system prefs on my MacPro mid 2012 running OS 10.12.6, I can not delete a ghost icloud account with an alias Icloud email address. I can log out of the address I do use and I can delete that account. This Ghost, however, I can not. I have tried dumping keychains, deleting the alias which is a .mac account, the legit one is a .icloud. I try and click the - to remove and it stays. I have logged into my test account and this Ghost account is not present and all is right in the world. Back on the main User Account IN the Internet Accounts the Ghost icloud says contacts and 2 more. Where oh where is this damn thing so I can delete it. I am not signed in to any icloud services, I have checked every ios device I own to double check that I am indeed signed out. I have scrolled through the Library, plist files, empty accounts folders, and other system files but I have had no obvious luck and I don't know what can go or stay. Has anyone an idea? Knowing that the Test account worked I am planning on my next step which will be a reinstall and then migrate slowly to the new system. Thanks for reading and the time. I am sure it is something simple.
Follow up on what I did once I realized my original user account was corrupted.
What I did was to create a new user account.
Grabbed all my files from that user account and moved them the new one.
I then went through each file, mainly photos and documents, and changed permissions.
After a week of dealing with duplicates, cleaning, deleting, etc. I was up and running with nearly the identical set up as my old user account. Doing this is a pain in the buttock.
The final step is to deal with iTunes and my new Photo app on the new account. iTunes shouldn't be an issue since it is ran on an external and all the files are there.
Photos, I dunno. I have 15,000 photos I am about to drop on it.
Things I learned: 1. back up each night, follow Jon F. Braun's advice to boot into your back up now and again to test it to see if everything works. This could have saved me a lot of time in finding WHEN my user account became corrupt.
2. the first thing anyone should do with a new computer is to make a dumb admin account that you do not touch. This SAVED me in getting into my iCloud account and activating it again. If I did not have that test account on my Mac I don't know what the app tech would have done. We had discussed this issue on the phone for over an hour trying everything until I realized I had this test account. Using the test account I could log into my iCloud and get things moving again.
3. Do maintenance once a month to clean out caches, dump old files, delete apps, run updates, and utility software.
4. iCloud is weird and finicky. Test it often.
Below are some links that I used, none worked but perhaps there is something in them that could help you with your user or iCloud issues.
