Deleting iCloud Keychain Device Access
I recently went to remove an account from Internet Accounts in Settings, and got a warning that said that the account would be removed "from all your computers using iCloud Keychain" — and two Macs were listed which were from previous employment. I was sure I removed iCloud accounts from these. How can I ensure that iCloud Keychain is no longer synced on machines to which I no longer have access?
