Is there a way to download the older MacTeX-2011? I am transitioning to a new mac and would prefer to have both MacTeX2011 and the 2012 version available. I thought I was in luck when I found the the page: http://www.tug.org/mactex/2011, but sadly the link does not work and neither do the mirrors.
You could try downloading using BitTorrent. The MacTeX 2011 torrent file is still online.
