=Installation on MacOS=
The preferred way to install Ansible on a Mac is with pip.

The instructions can be found in Installing and upgrading Ansible with pip. If you are running macOS version 10.12 or older, then you should upgrade to the latest pip to connect to the Python Package Index securely. It should be noted that pip must be run as a module on macOS.

'''Note''':
macOS by default is configured for a small number of file handles, so if you want to use 15 or more forks you’ll need to raise the ulimit with sudo launchctl limit maxfiles unlimited. This command can also fix any “Too many open files” errors.

Once pip is installed, please put below command to install ansible.
 python -m pip install --user ansible
'''Paramiko''' is a Python (2.7, 3.4+) implementation of the SSHv2 protocol [1], providing both client and server functionality. While it leverages a Python C extension for low level cryptography (Cryptography), Paramiko itself is a pure Python interface around SSH networking concepts. Detailed usage and API documentation can be found at our code documentation site, docs.paramiko.org. In order to use the paramiko connection plugin or modules that require paramiko, install the required module 2:
 python -m pip install --user paramiko

Ansible can also be installed inside a new or existing virtualenv:
 python -m virtualenv ansible 
This command will create new folder 'ansible' inside home folder, ~/ 
 source ansible/bin/activate
And, this command will activate them
 python -m pip install ansible
And, finally, install ansible inside the virtual environment.
'''Note''':
Default inventory folder in MacOS is in /usr/local/etc/ansible/hosts, but, you may just want to change the defauly by issuing export command as below
 export ANSIBLE_HOSTS=/path/to/your/folder
One can also write above command into ~/.bash_profile, to make the configuration persistence.
