I have been using LiveTeX since 5 years ago. I have always used TeX Live utility to keep up-to-date my LaTeX distribution. Today I woke up with this question:
I want to know if there is an un-official MacTeX (or TeXLive) repository?
TeX - LaTeX Stack Exchange is a question and answer site for users of TeX, LaTeX, ConTeXt, and related typesetting systems. It only takes a minute to sign up.

In the case of TeX Live Utility, you would drag the URL http://tlcontrib.metatex.org/2013/ to its address bar, or add it to the list of repositories. It appears to only be available for TL 2010-2013, though.
It is possible to use additional repositories which provide software not distributed as part of TeX Live (or MiKTeX). norbert explains in a comment that it is possible to configure additional local repositories using these instructions, and that there are a number of supplementary repositories designed to be used by tlmgr
, TeX Live's package manager, as supplements to the main repos. These supplementary repos offer packages which are not included in TeX Live. While these may include packages not available from CTAN, many packages will be available from CTAN.
TLContrib is one example of such supplementary repository.
CTAN publishes many packages and resources which are not included in TeX Live. Some of them are not included in MiKTeX either. These exclusions may be for licensing reasons but they may also be for a number of other reasons:
biblatex
was in this category for a long time: many people used it but it was not included in TeX Live because the author considered it not ready for production.Note that some packages are partially included in TeX Live. For example, the documentation of both chessboard and chessfss is missing from TeX Live because the author elected not to supply the source for the PDF. Note that this does not prevent the documentation being available on CTAN.
CTAN itself includes software published under a variety of free and non-free licences. Many of these would not be acceptable to TeX Live and some would not be acceptable to MiKTeX. Obviously, CTAN will not sell software on authors' behalf so it will not host commercial software. But shareware is acceptable, as are a number of 'free-as-in-beer but not free-as-in-freedom' licences. (Since TLContrib is free-as-in-beer as far as I can tell, I assume it is not in the business of selling software, either. Moreover, licensing restrictions would prevent TLContrib from including some software available from CTAN.)
tlcritical
answers this question specifically (but still interesting). tlptexlive
definitely is on-topic, though, and the documentation for setting up local repos sounds useful as part of a general response to what is quite a generic question.
CTAN
supported. I mean "un-official" because you can get packages that are not fully accepted forCTAN
or that are independently developed.
