Downloading MacTeX Installing MacTeX. It is not necessary to remove the earlier TeX Live installation before installing a new one, and indeed we don't recommend that because MacTeX makes it easy to revert to the older version if the new version has a flaw. If you really need the extra space, other sections of these web pages explain how to remove older versions of MacTeX. A small number of users like to keep several versions of TeX Live available, even when they buy a new computer running the latest macOS.
This is certainly possible because older versions of TeX Live continue to work on new systems, and versions containing only Intel code run fine on Arm machines. The old version can be installed on the new computer by copying it from an older machine, or by obtaining it from CTAN. For details, visit the web page here. There is one complication.
TeX Live Utility can update an old distribution to the version just before that version was retired. The reason is that TeX Live Utility calls the program tlmgr in the older distribution, and this program depends on various utilities in that older distribution. One of these utilities determines the operating system being run and expects a number starting with 10, like But Big Sur returns a number starting with This bug was discovered and fixed in TeX Live within a week of the initial first beta of Big Sur in June, , and thus long before the release of Big Sur to the public.
Installation Errors. Updating Various Pieces After Installation. To obtain the distribution, click the link below. All install packages are developer-signed and notarized by Apple. While downloading, please skim read the rest of the page. Users who run into trouble often write us without noticing that the solution is on this very page. MacTeX requires macOS The same source code is used to compile both types of code, so Apple's Arm and Intel machines are on exactly the same footing.
After downloading, move the file MacTeX. Follow the straightforward instructions. Installation on a recent Macintosh takes about ten minutes. A copy of this document is available here.
The installer presents a Welcome page. Please provide screenshots where appropriate. All TeX distributions consist of both binaries including scripts and packages including classes.
It is important to understand that for TeX Live these two parts of the distribution are effectively on separate update schedules, and this can lead to some confusion during the period in which the major updates of binaries is taking place. The TeX Live binary part of the distribution undergoes a major update only once a year, while the packages can be updated constantly.
This system, however comes at a cost: once a new binary version of TeX Live is available, package updates for the previous years are no longer available. This means that if you have e. After that point, your system will not be able to update any packages ever again using the normal package manager.
You can update individual packages manually via CTAN, of course. The major binary updates of TeX Live which come out yearly must be installed as if you were installing a fresh distribution. Since each version is installed in a folder named by its year, it's possible to have multiple distributions on the same system. Once you have a version of TeX Live installed, you can update the packages as often as you like using the package manager tlmgr.
The simplest command is:. See the MacOS answer for more details on that. Once a year, the TeX Live packagers must "freeze" the system so that the latest version of the distribution with new binaries can be produced and tested. This means that there is a period during which tlmgr will no longer be able to update the current year's distribution even though the new year's distribution is not publicly available.
This freezing is necessary so that the new distribution can be guaranteed to work. Once the current year is frozen, it will never be able to be further updated.
To keep up-to-date, you will need to install the next year's distribution when it becomes available. For additional information, see Why does TeX Live "require" yearly updates? On Windows, an Administrator-privilege Command Prompt is run by finding the Command Prompt icon in the Start Menu, right clicking to obtain the options and choosing 'Run as Administrator For Mac users, using sudo will be sufficient as tlmgr will be available on the path.
This may not be the case in Linux distributions: see below. If you installed your TeX Live system using a Linux package manager for example, apt-get , then there is no guarantee that it will be updated on the same schedule as the regular TeX Live.
In most cases the updates lag by some time, often years, depending on the particular version of Linux you are running.
For this reason, most experienced TeX users who run Linux install the vanilla TeX Live distribution directly , bypassing their OS package manager completely. You can do so for example by running sudo -s from the command line, which will log you in as root. Alternatively, you can run tlmgr with the full path, for example on a bit installation.
When moving to a new version of TeXLive e. If you start this app it will connect with CTAN and list up the possible updates. Now make sure that you are not using one of the packages that will be deleted.
If you are using one of them save its files to your local texmf tree. You may also check what's changed in the updated packages, after installing them. Note on macOS and Linux: This answer is written with Windows in mind, but MikTeX offers the same graphical user interfaces on the other operating systems, too! Consult the MikTeX docs to get to know how to open them. MiKTex can be updated with 2 methods. With method 1 only updates are possible — it's intended for this task —, method 2 uses the package manager, originally intended for manual package installations and uninstallations.
Unlike in TeXlive also binary files are updated if necessary. If you installed MiKTeX with Administrator privileges as a multi-user installation , you will have ' Admin ' versions of the commands described here. To fully update your system, run the update both with and without the ' Admin ' mode enabled. This is necessary as with auto-install enabled, MiKTeX will have managed files both in the system-wide Admin area and your own user tree. If you installed MiKTeX with Administrator privileges, you will have to go through the following steps once in user mode and once in Admin mode.
Choose one of the two options. If you choose your mode the console may restart and you will be met with.
Go to Updates in the sidebar to the left. Press on Check for updates and wait for MikTeX to fetch the update information from the package database this may take a while, hang in there.
If updates are available they will be listed below and you can install them by clicking on Update now. You can deselect certain packages. Note that if important system updates are available, not all packages may be checked for updates initially.
Do not select more packages, in that case, run the updater with only the checked packages first and then re-run it afterwards. On the second run, all other packages should be selected and will be updated. The windows is greyed-out while the packages update. It shows a short progress report. Most MikTeX links in the start menu will lead to the console directly.
Here, one can choose the package repositories and adjust connection settings. Pressing Next button will take you to the next window which will show, after a search through the repository for update-able packages if any. Usually, all packages are already selected. FYI: I think we can combine tlmgr update —self and tlmgr update —all into one line comand: tlmgr update —self —all.
November at Does this mean that there is no way to update packages with Ubuntu, without uninstalling it and installing it from source? Are there any separate repositories from Texlive for Debian distributions? I have some conflicts with some packages I need fontspec and Tikz , so I have to update.. Have a look at this Ubuntu help page on how to update Latex packages manually. June at Hey Dan, Thanks for your comment. Glad you found my page useful.
Cheers, Tom. If you prefer the terminal, try: sudo tlmgr update --self sudo tlmgr update --all Linux Ubuntu : It is a little tricky to update TeX Live under Linux and as usual depends on the distribution as well as your local settings.
Like this: Like Loading May at On linux, you can usually use standard package tools to update tex live e.
You can, but those packages are often woefully out of date.
