Actually it would not be a clone of Total Commander but rather of the Norton Commander, which is a parent of a large family of 2-pane file managers.
##muCommander (homepage, wiki).
It's a 2-pane file manager, providing an interface, similar to those of the Norton Commander family, but in the look and feel, native to OS X. It's actually cross-platform and available for any popular OS.
muCommander is free and released under the GNU General Public License. It's written in Java and requires it to run.
###Installation on OS X:
Homebrew:
brew cask install mucommander

This one is really NC-style. Its features and installation are discussed in this question: http://superuser.com/q/128700/450318

A great list of file managers (not all of them are 2-pane) is available in Wikipedia: Cross-platform file managers.
