TeX - LaTeX Stack Exchange is a question and answer site for users of TeX, LaTeX, ConTeXt, and related typesetting systems. It's 100% free, no registration required.

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/2010 and /usr/local/texlive/2011 form old Mac to new Mac.
  • Install TeXLive2012 which created /usr/local/texlive/2012 on new Mac.

On my older Mac I have the following in my Preferences panel:

enter image description here

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.

I'm not in my Mac right now, but I believe the explanation relies inside /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
    
You should try copying also /Library/TeX/Distributions/TeXLive-2011.texdist/ –  egreg Aug 16 '12 at 23:18
    
@PauloCereda: There were two directories ~/Library/texlive/2010, and ~/Library/texlive/2011. I copied those over (and rebooted), but still only see TeXLive 2012 in the Preferences. –  Peter Grill Aug 17 '12 at 4:22
    
@egreg: I also copied over /Library/TeX/Distributions/TeXLive-2010.texdist and /Library/TeX/Distributions/TeXLive-2011.texdist (and rebooted), but still only see TeXLive2012 in the Preferences Pane. –  Peter Grill Aug 17 '12 at 4:24
    
@PeterGrill: Interesting, I think it should work. Maybe /Library/TeX/Distributions/TeXDist-description.rtf has some hints on what's happening, but as far as I read the document, the TeX pane in the Preferences should recognize .texdist's automatically. –  Paulo Cereda Aug 17 '12 at 12:10

You should also copy

/Library/TeX/Distributions/TeXLive-2011.texdist/

which is what the Preference pane uses to know that the distribution is present.

Also the "home" folders referring to variable parts of the distribution should be copied:

~/Library/texlive/2011

but this has minor priority, as it contains things that will be rebuilt in case of need.
