TeXShop is a Tex previewer for Mac OS X. For more information, click on Ghostscript 10.04.0 was released on Sept 18, 2024. An install package is provided below. The package has universal Intel and Arm binaries and works on macOS Mojave and above. The associated install package for Ghostscript-10.04.0-Extras, containing the Ghostscript Library and muTool 1.24.9, is also provided below. These extra programs are required by only one binary in TeX Live, dvisvgm. In case of trouble, revert to Ghostscript 10.03.0. Ghostscript 10.03.0 was released on March 7, 2024. An install package is provided below. The package has universal Intel and Arm binaries and works on macOS Mojave and above. The associated install package for Ghostscript-10.03.0-Extras, containing the Ghostscript Library and muTool 1.23.11, is also provided below. Ghostscript 9.50 was released October 15, 2019. Below is a signed and notarized Macintosh install package for this version of Ghostscript. The package works on macOS High Sierra and above, for Intel. The version of the package linked below was released on December 22, 2019; the new version has a Custom mode which can also install the ghostscript library libgs.dylib in /usr/local/lib. This library is required by dvisvgm to enable certain operations, but most users will not need to install it. The Hint Project is a typesetting project by Martin Ruckert, described on the web page https://hint.userweb.mwn.de. The command line typesetting programs hitex and hilatex from this project are in TeX Live. They convert TeX and LaTeX source files to "hint files" rather than "pdf files"; hint files contain information needed to reflow the text if the user resizes the view or magnifies the text. Ruckert wrote hint file viewers for various operating systems; his viewer for macos is in the MacTeX install package. That viewer is also available below, together with a README file with more information about the project.

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 2024. Here is an install package for the Macintosh. The link below downloads a "LocalTeX" preference pane. This pane allows a user to select the active TeX distribution, and overrides the choice made for all users by TeX Live Utility. It also allows users to install TeX in their home directory and to select distributions installed on a thumb drive or external hard disk. It does not modify any data used by the TeX Dist pane and works on High Sierra and above. The download includes the LocalTeX pane, documentation, and full source code, but a glitch in Apple's notification system forces users to compile the pane using the included source and XCode. The link below is for what we hope are very rare users, who have Arm machines but are running TeX Live 2020. It is an install package which reaches into the TeX Live 2020 binary directory and replaces each x86-64 binary with a universal binary with both x86-64 and arm code. The binaries are still in /usr/local/texlive/2020/bin/x86_64-darwin because the distribution was designed to look for binaries there. We strongly recommend that Arm owners upgrade to a later TeX Live, since these support Arm and Intel on an equal footing.
