This is just my personal preference.
Obviously if you used bridged then you will not be able to connect to 127.0.0.1 (ie localhost) as you will need to use whatever IP the sandbox gets. Ie on my network it is a 192.168.1 address.
Virtual Box will be setup with different defaults to VMWare – we can’t control how your virtualization software is configured.
The PDF guide for the mac is basically the same as windows:
Open VMWare player, click on import. Or double click on the VMWare machine.
You could create a VMWare machine with CentOS on it and configure the networking and install a single node cluster if you wanted it to be fully reachable from within your network.
The Sandbox does work if you SSH into it and ensure it is listening on the correct ports – this is where you Virtualization software comes into it.
I would look at VMWare documentation if you are not familiar with the settings – otherwise I am happy to help.
