Issue on m1 Mac install.command

Hi,

Ive been trying to sort this out for ages and nothing seems to work. Ive uninstalled every single version of python and installed the new one, installed multiple versions. Done every fix i found on google. Still wont work

/Downloads/instapy-quickstart-master/installation/MacOs/install.command: line 3: [: !=: unary operator expected
Please install the latest version of Python from https://www.python.org/downloads/

Sorry for the inconveniences
====================
Pip is installed
====================
Chrome is installed
====================
Error! - Please double check the installation of Python, pip, and Chrome
Sorry for the inconveniences

this comes up on install.command

Start with installation/MacOs/install.command, especially line 3, and reproduce the install on an M1 Mac while checking how the script detects Python, pip, and Chrome. Done means the command completes without the unary-operator error and accepts the installed dependencies.
