How to install TexMaker on Mac?
It's not 100% clear to me what you've actually tried, but give this a go:


Launch Terminal
Enter the following command:


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


Press enter and wait while the command runs
When it's complete, enter: brew cask install texmaker


Let me know how you go.
