All info is in the Sony iManual. If you are using Mac iOS device just download iMedia Share from App Store (free) and it will mirror your iOS device to your your Sony no problem (after setting up WiFi Direct which is also easy)
As for mirroring MBP you can use HDMI of course and make sure system preferences are looking at the Sony in 'Display Settings'. Or you can of course stream wirelessly using your LAN / WiFi connection.
I bought a new W6 last month and it is all up and running with no cables.
Also you can reset the internet start page to a URL of your choice - it doesn't have to be the Sony products website page as your start page.
Hope this helps
