MacTeX installs the front end TeXShop in /Applications/TeX and most people will access TeX using that front end or a similar one. Most users access TeX using a 'front end', a program providing an editor to enter TeX source and a preview window to view the typeset output. MacTeX installs TeX Live, the actual TeX Distribution, in /usr/local/texlive/2020, a location often hidden in the Finder. Therefore we replaced /usr/texbin with /Library/TeX/texbin. 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. On older systems, you may have seen the link /usr/texbinwhich did the same thing. The GUI programs we supply should automatically configure themselves. Configure your GUI programs to use this link. MacTeX writes a symbolic link /Library/TeX/texbin which indirectly points to the TeX Live binary directory. If other problems are reported during installation, skip to the section 'Installation Errors' below. In all cases known to us, rebooting the Macintosh fixes this problem. Users who use MacPorts or HomeBrew may prefer to use the Ghostscript provided by these projects if so they should use 'Customize' to disable Ghostscript installation.Īt the end of installation, the installer will report 'Success.' But sometimes, the installer puts up a dialog saying 'Verifying.' and then the install hangs. Most users will take the standard installation and ignore 'Customize'. The final page also has a 'Customize' button, which leads to a panel allowing users to decide which pieces to install: Ghostscript, the Ghostscript Library, the GUI applications, and TeX Live itself. Then it presents a ReadMe page with more information.It presents a Software License page, and then a Final Page clicking the 'Install' button on this page will start the actual installation. Installation on a recent Macintoshtakes about ten minutes. After downloading, move the file MacTeX.pkg to the desktop or another convenient spot,and double click it to install.
