Howdy,

Concerning TeX Live 2012:

First, there is nothing for tlmgr to (re)install because the pretest has been frozen in preparation of a possible release.

Second, even if there was something to install you would have to point TeX Live Utility (or tlmgr) to one of the pretest repositories rather than the normal repository.

Third, if you wanted to update 2011 you would go to the TeX Distribution Preference Pane in System Preferences and select TeX Live 2011; when you installed the MacTeX-2012 pretest the active distribution was automatically set to TeX Live 2012.

Concerning TeX Live 2011:

There was a short time this past year when the structure of the experimental LaTeX3 was changed (Joseph Wright is involved with that) and one structure was not completely replaced by the new structure. I believe that was sorted out but somehow you got stuck in the middle.

As Joseph Wright said, just use the TeX Live 2012 (pretest). Oh, you are obligated to note any incorrect behavior but I haven't seen any problems for the work I do.

Good Luck,
