I have a huge problem with public beta 2. Everything was fine, and then I woke up the machine Saturday and it said that Mail had to reindex. Okay, I clicked and allowed it to do that. Some 200,000 e-mails. Took an hour. So I opened it up, and it told me to put in the password for one of my four accounts. I did so. Wrong, it said. Tried again. Wrong. Tried the other one it asked for. Wrong. Checked with Safari. Wrong. And as the process went on, finally, all of the accounts weren't responding. They weren't in the Accounts under System Sharing. Eventually, I realized it was an iCloud problem. All the passwords were in iCloud Keychain. But I couldn't get into iCloud. My phone, iPad and Apple TV, fine. So I changed my Apple ID. Eventually, when I got all the devices signed in with the new iCloud, everything was great. Except. I open Mail, and all the menus are blanked out except the useless ones. No Rebuild, certainly. Under Mailbox, only Go To-> and Move To-> Are available, but their pointing to grayed out, generic Mailbox 1, Mailbox 2, etc. Anybody tell me how to reconnect to the mboxes, or wherever the hell they are? Something in Terminal?
