TeXShop is a Tex previewer for Mac OS X. For more information, click on
The link below downloads a "LocalTeX" preference pane. This pane is a complement to the
"TeX Dist" preference pane installed by MacTeX, which allows a user to select the active TeX distribution.
The local pane allows individual users to override the choice made for all users by the TeX Dist
pane, and to select distributions installed on a thumb drive, external hard disk, or home directory.
It does not modify any data used by the TeX Dist pane and works on Mavericks and above. The download includes the LocalTeX pane, documentation, and full source code.

Minimal TeX is a very small distribution of TeX for the Macintosh. It only contains engines for Plain TeX and variants of Plain TeX, but nothing about LaTeX. It is based on the TeX Live "minimal scheme" for 2018. Here is an install package for the Macintosh.
Basic TeX is a small distribution of TeX for the Macintosh, available on CTAN
and from the MacTeX site at http://tug.org/mactex. Below is a paper about making this distribution.
Following that is a signed and notarized package to install BasicTeX-2019-Hardened, for testing Apple's new requirements that binaries adopt a hardened-runtime.
Before 2015, MacTeX installed a link at /usr/texbin which pointed indirectly to the TeX binaries. In El Capitan, /usr is not writable by users.
Therefore, MacTeX-2015 and BasicTeX-2015 and later install a new link, /Library/TeX/texbin,
which is entirely equivalent to the original link. Most GUI apps now automatically reconfigure themselves to use the new link on El Capitan.
A few users upgrade to El Capitan, find that their older version of TeX no longer works, but don't want to download the enormous MacTeX-2015. These users can download and install FixLink below, which writes the new symbolic link for them. After that, older distributions work fine on El Capitan.
