MacTeX


MacTeX is a free redistribution of TeX Live, a typesetting environment based on TeX. While TeX Live is designed to be cross-platform, MacTeX includes Mac-specific utilities and front-ends. It is also pre-configured to work out-of-the-box with macOS, as it provides sensible defaults for configuration options that, in TeX Live, are left up to the user to allow for its cross-platform compatibility.
MacTeX is packaged and distributed by the MacTeX TeXnical working group, a subgroup of TeX Users Group. TeX Live is distributed by the TUG, making MacTeX less a fork of TeX Live than a customised repackaging.
The full MacTeX install package contains three subpackages:
As of 2019, the content of the full MacTeX installation exceeds 4 GB in size. However, a substantially smaller version of MacTeX, BasicTeX, which does not contain Ghostscript or the aforementioned GUI programs, can be used in its stead along with a TeX editor as well.
