How to install TexMaker on Mac?

Solution 1:

Texmaker is only an editor, you need to install TeX/LaTex separately and configure Texmaker to find the correct binaries. From Configuring the latex related commands:

Texmaker can't compile yours documents if the paths to the LaTeX related commands are wrong. The default settings should work with the recent and standard LaTeX distributions, but you should have to modify them ("Configure Texmaker" -> "Commands").

There are several TeX/LaTeX packages for macOS out there, I'm using MacTeX for several years now.

Solution 2:

It's not 100% clear to me what you've actually tried, but give this a go:

1. Launch Terminal
2. Enter the following command:

ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null ; brew install caskroom/cask/brew-cask 2> /dev/null

3. Press enter and wait while the command runs

4. When it's complete, enter: brew cask install texmaker

Let me know how you go.
