I can't seak for the first two methods but I rarely have to run it more than once in a row to get things to behave properly. After you open MCC go to Cache Cleaning; do a Light Cleaning but check all three check boxes to clean the Local, System and All users caches and press Clean. After a short delay a dialog box comes up and the OS will eventually reboot. After I reboot I wait a short while for HD activity to stop.

I rebuilt Launch Services using Onyx. And did light cleaning for user, all users, and system using Mavericks Cache Cleaner. Still same problem. 

A clue: when in Terminal I run mdls on any .tex file, I see, among other things: 

     kMDItemContentType             = "com.barebones.bbedit.tex-source" 
     kMDItemContentTypeTree         = ( 


     kMDItemFSTypeCode              = "TEXT" 
     kMDItemKind                    = "TeX source file" 

This is the case even though I used Get Info not only to open the .tex file with TeXShop.app, but to do a Change All for "all documents like this one".
