myQLM Installation on MacOS

There are two methods supported to install myQLM on MacOS.

IMPORTANT: Do not install Python 3 twice using both methods. Only follow one method or the other and install Python 3 once. Installing two Python 3 from different sources may have consequential behaviors (e.g. segmentation fault).

myQLM Installation on MacOS using Homebrew
Install Homebrew with the following command (requires sudo access, code taken from https://brew.sh):
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
At the end of installation, it will ask to put Homebrew in the PATH.
Run the commands specified on-screen.
Example:
echo '# Set PATH, MANPATH, etc., for Homebrew.' >> /Users/johnsmith/.bash_profile
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> /Users/johnsmith/.bash_profile
eval "$(/opt/homebrew/bin/brew shellenv)"
These commands are necessary to setup Homebrew to be used.
Verify Homebrew is available with the command:
brew
Next is to install Python 3 using brew.
Install the latest Python 3 with the following command:
brew install python3
You can specify the version of Python 3 by using ‘@’ before the version number and after ‘python’:
brew install python@3.9
Refer to the Compatibility Matrix for supported Python versions.
Information regarding Python 3 Anaconda running along Python 3 Homebrew
Unfortunately, there is no easy way to get both Pythons working at the same time.
For Anaconda users, after installing Homebrew, Homebrew will become the default.
To reverse this change, comment out the following line in your .bash_profile:
eval "$(/opt/homebrew/bin/brew shellenv)"
Log off and log back in.
Make sure you are using Homebrew Python 3[1] before proceeding to myQLM Installation.

myQLM Installation on MacOS using Python.org
Go to https://python.org/download.
Download the latest Python 3 and follow through the installation setup (requires sudo access).
After installation is complete, open a Terminal.

Information regarding Python 3 Anaconda running along Python 3 from Python.org

Unfortunately, there is no easy way to get both Pythons working at the same time.
For Anaconda users, after installing Python 3 from python.org, python.org will become the default.
To reverse this change, comment out the following line in your .bash_profile:
PATH="/Library/Frameworks/Python.framework/Versions/3.8/bin:${PATH}"
Log off and log back in.
Make sure you are using Python 3[2] from python.org before proceeding to myQLM Installation.
