+1 for reliable installation. There were some cases (issue33220, issue30944) where the installer was detected as a Virus by some vendors which would be reduced since this is installed from the App store as a verified app. I hope this will also reduce the scenarios where users need to resort to bug tracker with log files when there are installation failures [1] providing a more smooth one click install.

There is a long standing open issue [2] to make `pip install --user` as a default which I hope gets resolved and there is an issue with using `pip install --user` inside a virtualenv which seems to block the earlier issue [3]

Thanks a lot for this!
