For Mac users who have problems with Avogadro, you may need to install some libraries to support it.

First, please drag the unzipped Avogadro to your /Application directory.

If HomeBrew (A software package manager for MacOS and Linux) is not installed on your computer, you can run the following scripts

$ /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"

If you get the error message from Avogadro saying

Library not loaded: /usr/local/opt/libpng/lib/libpng16.16.dylib

please do

$ brew install libpng

If you have problems loading your .out file

please try

$ brew install open-babel
