To switch, use the Configure menu item "Change Default TeX Live Version." 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. Users who run into trouble can switch to the previous distribution until the new distribution is fixed. MacTeX does not overwrite the TeX distribution from the previous year. MacTeX installs the front end TeXShop in /Applications/TeX and most people will access TeX using that front end or a similar one. Typical 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. This location is often hidden in the Finder. MacTeX installs TeX Live, the actual TeX distribution, in /usr/local/texlive/2023. The GUI programs we supply will automatically configure themselves. 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. It presents a Software License page, and then a Final Page clicking the "Install" button on this page will start the actual installation. Then it presents a ReadMe page with more information. READ ME FIRST installed there, which explains how to find and use LaTeX. When installation is complete, go to /Applications/TeX and read the document For instance, if you have MacTeX 2022, you can just drag the folder /usr/local/texlive/2022 to the trash.Īfter downloading, move the file MacTeX.pkg to the desktop or another convenient spot,Īnd double click it to install. It will be easy to eventually remove that earlier distribution. Your earlier distribution will remain and can be used in case you run into difficulties with the 2023 version. Other QuickPreview options include Environment, Subdocument and Maths group.It is not necessary to remove earlier TeX distributions before installing MacTeX, because the distribution will be installed in a separate location /usr/local/texlive/2023. I tested the QuickPreview > Selection option. It then typesets this document and displays the result, if successful. It copies the preamble to a file in a temporary directory called preview.tex, along with the selection, wrapped in a document environment. Note that this also creates a file called _region_.tex.Ĭonsider this file (called, say, fulldoc.tex): \documentclass line to figure out where the preamble ends. Then hit C-c C-r RET to compile that selection. In order to selection the region, the easiest way is to move the cursor to the start (or end) or the desired region, hit C-SPC (or M-x set-mark-command) to set the mark, then move it to the end (or start) of the region. The command tries to be 'smart' about it, so if you do C-c C-r RET C-c C-r RET (i.e., run the same command on the same section twice) it will first compile, then, second, open a viewer for resultant PDF. With Emacs and AUCTeX, it is as simple as highlighting the portion of the text you want to compile and then hitting C-c C-r (or M-x TeX-command-region).
