Installation fails when trying to install Unity AndroidPlayer on macOS

I managed to defeat the issue by installing the required packages from the Unity Hub, instead of manually downloading & installing.

Start Unity -> click Installs -> reveal Add Modules by clicking the vertical 3 dots and select the modules required by clicking on the checkboxes.

I managed to install Android support using the full Unity3D installer and making sure that the Android support is selected. Could be a specific problem with the AndroidPlayer installation package.
