How to download the latest sosftware!

Hi everyone,

Thought I would check & try downloading the latest software for my new MCS, built March 2014.

I went to the mini software website & chose the option to download software.

1st Question: it doesn't ask for VIN number or model, so is there just one standard generic software for all Mini's no matter what spec you have?

2nd Question: can you download the software from a Mac?

I downloaded the software from the website and transferred that to a USB stick. I plugged that into my mini and chose software update but it says no USB or software can be found.

I have HUD, media pack XL, satnav, and enhanced Bluetooth.
