There are two possible default modes for what happens next: a graphic mode and a pure text mode. If you have admin status (and most users on single owner machines do), type your ordinary password. You might want to copy and paste this command rather than typing it because Unix is very picky the last item is TL, but in small letters. install-tl" without the quotes, and press return. Terminal will "change directory" to the install-tl folder. Activate the Terminal window by clicking in it if necessary, and press RETURN.

Then drag the install-tl folder created previously into the window and drop it there. Type the word "cd" without quotes and a space in the resulting window. Open Terminal in /Applications/Utilities. A typical folder name is "install-tl-20210527", but the exact name varies by date. Move this file to your home folder and click to untar it, producing a folder. Your Mac should automatically unzip it and you will find a file named "install-tl-unx.tar" in your downloads folder. To begin the installation, click the link to download this item. If installation fails, read the section following this one.

Please follow the instructions below and try to install TeXDist-2021 when asked to do so. We do not know when it works and when it fails because we do not have machines running systems earlier than Mojave. IMPORTANT: After this page was written, we discovered that TeXDist-2021 does not work on some older systems. (The second step is automatically done by MacTeX.) This second step configures TeX so TeX Live Utility and various GUI programs can find it without further configuration. After step one is complete, obtain a small install package from the following link TeXDist-2021, and install it. The first installs the TeX Distribution on the Mac exactly as it is installed on Linux and Unix machines this step is described in the following paragraphs.

How to install TeX Live with the Unix Script This is not possible with the MacTeX install package, but it is easy to do using the Unix install script which TeX Live supplies. Most Mac users with older systems already have versions of Ghostscript and the GUI programs which work on their systems. These binaries require Intel processors for systems 10.6 (Snow Leopard) and higher TeX Live labels these binaries x86_64-darwinlegacy. However, Mojca Miklavec compiled the 2021 binaries for older systems on Snow Leopard her binaries are also in TeX Live. TeX Live combines these binaries into universal binaries which run natively on both kinds of computers and labels these binaries universal-darwin. In particular, the TeX Live Intel binaries were compiled on an Intel Mojave computer and the TeX Live Arm binaries were compiled o an Arm Big Sur computer. MacTeX-2021 supports macOS 10.14, 10.15, and 11, Mojave, Catalina, and Big Sur. They are installed in /Applications/TeX, together with a small amount of documentation telling new users how to get started. These are the programs users actually see and use to interact with TeX. The third piece contains four GUI programs: TeXShop, TeX Live Utility, BibDesk, and LaTeXiT.

Most pieces of TeX Live do not require Ghostscript. It is installed in /usr/local/bin with support files in various /usr/local folders. This is a command line program which users do not see directly.

The second piece is Ghostscript, which can process postscript, eps, and pdf files.

This software does the actual typesetting. It is installed in /usr/local/texlive/2021 and thus hidden from most users. The first, TeX Live, is a gigantic collection of command line programs like TeX, LaTeX, XeTeX, LuaTeX, and associated style and class files, fonts, documentation, etc.

See also More on Unix Script for other reasons to use the Unix script on more recent systems, and special instructions to make it work on these systems. The MacTeX-2021 package does not support these systems, but TeX Live 2021 can be installed another way using the Unix install script.

This page is for users who want to install TeX Live 2021 on macOS 10.6 through 10.13, Snow Leopard through High Sierra.
