From an earlier question of mine, it was determined that one can not obtain the latest version of older releases (ex. TeXLive2010, TeXLive2011). I am upgrading my Mac and would like to know the process of copying over manually the files from a Mac that has TeXLive2010 and TeXLive2011 installed. I'd prefer to not use the Migration assistant, so that I can control exactly what is being updated.
So, what I naively tried was:
- Copy
/usr/local/texlive/2010and/usr/local/texlive/2011form old Mac to new Mac. - Install TeXLive2012 which created
/usr/local/texlive/2012on new Mac.
On my older Mac I have the following in my Preferences panel:

But on my new Mac I only have TeXLive-2012 shown, and want to know how to get that to show the other two versions.
So, what other files do I need to manually copy over so that I can have access to all three versions? Deleting and reinstalling TeXLive2012 is not a problem.
Notes:

/Library/TeX. There must be something there that governs the TeX Distribution Data structure. I found some hints here.:)– Paulo Cereda Aug 16 '12 at 17:21/Library/TeX/Distributions/TeXLive-2011.texdist/– egreg Aug 16 '12 at 23:18~/Library/texlive/2010, and~/Library/texlive/2011.
