I ran into an issue with my KeyChain recently, and after wiping it out to start fresh I've been unable to add Internet accounts to my accounts in System Preferences. When I enter my password for a given account it trys to authenticate with the spinning loading animation, then goes all grey and doesn't do anything after that. Has anyone had a similar issue or have any suggestions? Thanks! P.S. There should be an image attached of the loading screen once it has frozen.
