Many problems after data migration
I recently installed an SSD on my Early 2011 MBP. I put my old drive in an enclosure and after installing Mavericks 10.9.4 on the new drive, I used Migration Assistant to copy over all my Users/Applications etc. Many problems ensued. One of the users migrated without any (major) problems. The other user had the following issues:
1) Every time I log in, several programs automatically open (Word, Powerpoint, Messages, Preview, Firefox). Even if I quit them all, log out and/or reset, then log back in, they all open back up again. This didn't happen before. None of these programs are in Users & Groups --> Login Items.
2) iCould, Facetime and Messages all ask my for me AppleID password, every time I log in. Facetime even asks for the password twice (I put it in correctly. If I put it in incorrectly it lets me know). It does this every time I log in.
3) Facetime and iMessage won't connect to the network. However, if I make a new user and sign in to Messages it works, so I know the network is fine.
4) Every time I start Firefox, it opens to the "recovery" page. I can delete the profile information, and it gets rid of this problem, but then I have no history/saved passwords etc. and that defeats the purpose of having my information migrated over.
I've googled the above issues and tried all the solutions I could find but nothing works. I'm fairly computer literate but this is causing me to pull my hair out! Any help would be appreciated. Thanks.
MacBook Pro, OS X Mavericks (10.9.4)
