Special Notes for Catalina
MacTeX-2019 works fine on Catalina once it is installed. When Catalina was first released to developers, Apple said that install packages for Catalina must be notarized and software installed must adopt a hardened runtime. These conditions hold for BasicTeX-2019 and Ghostscript, but not for MacTeX-2019. However, the requirements have been turned off for most betas of Catalina and seem to be still off in the release version, so MacTeX-2019 should install without trouble.
In one beta version of Catalina, perhaps beta 5, the restriction was turned on and the MacTeX-2019 install package refused to install. An experimental notarized version of MacTeX-2019 installed fine during that beta period and is available at http://tug.org/~koch/MacTeX-2019.pkg. It will replace the old MacTeX-2019 install package as soon as Apple reinstates the notarization restriction.
After downloading, move the file MacTeX.pkg to the desktop or another convenient spot, and double click it to install. Follow the straightforward instructions. Installation on a recent Macintosh takes about ten minutes.
At the end of installation, the installer will report "Success." But sometimes, the installer puts up a dialog saying "Verifying..." and then the install hangs. In all cases known to us, rebooting the Macintosh fixes this problem. After the reboot, install again.
If other problems are reported during installation, skip to the section "Installation Errors" below.
MacTeX writes a symbolic link /Library/TeX/texbin which indirectly points to the TeX Live binary directory. Configure your GUI programs to use this link. The GUI programs we supply should automatically configure themselves. On older systems, you may have seen the link /usr/texbin which did the same thing. When Apple produced El Capitan, they modified the system so users could no longer write directly to the /usr directory and this rule remains in effect today. Therefore we replaced /usr/texbin with /Library/TeX/texbin.
MacTeX does not overwrite the TeX Distribution from the previous year. Users who run into trouble can switch to the previous distribution until the new distribution is fixed. Long ago we installed a Preference Pane which could do this switching, but this functionality is now in TeX Live Utility, which is in /Applications/TeX. To switch, use the Configure menu item "Select Default TeX Live Version."
MacTeX completely configures TeX, so after installation it is ready to use. Go to "/Applications/TeX/Docs and Spell Utilities/READ ME FIRST.pdf" and read this short document to get started. The document leads a new user through the complete process of writing and typesetting a short LaTeX document. The location "/Applications/TeX/Docs and Spell Utilities/Documents" also contains "What is installed", which lists all the components of MacTeX and their installation locations.
MacTeX installs TeX Live, which contains TeX, LaTeX, AMS-TeX, and virtually every TeX-related style file and font. TeX Live is maintained by TeX User Groups across the world. TeX Live is compiled from the same sources for all platforms: Macintosh, Windows, Linux, Unix.
MacTeX also installs Ghostscript, an open source version of Postscript, and it installs the GUI programs TeXShop, LaTeXiT, TeX Live Utility, and BibDesk. In "/Applications/TeX/Docs and Spell Utilities/Spelling" it contains an install package for cocoAspell, a spelling service which does not mark LaTeX commands as misspelled.
