  This is an MSI Installer, so once the download finishes navigate to the Downloads folder and double-click on the installer to run it. Go through the installer wizard, as I'm sure you will have done hundreds of times by now. By default, the AWS CLI installs to C:\Program Files\Amazon\AWSCLIV2. That directory will be already setup so the aws command can execute at the command line.
  Once installed you should be able to open a command window, or PowerShell window, and run this command:
  For macOS the AWS team has made this task far more complex than necessary. You can install the AWS CLI either as a global command, or as a local command, and there is allowance for situations where your user ID does not have Administrator permissions. Further, there are additional commands to run for updating the AWS CLI, including an alternative if you do not have sudo permission.
  The most likely situation is that you are the sole user of the macOS computer you're using. In that most likely situation your account will have Administrator access, and can install global commands, and has the ability to run sudo to run commands as root. That's the model we'll discuss in this guide.
