Indesign CC Installation System Requirements Error

Hi!

I'm trying to download indesign CC however when I do there is an error message saying this - This computer does not meet the minimum system requirements for InDesign CC. Please refer to the system requirements in the Help documentation for a full list of hardware and software requirements for InDesign CC.

I have attached an image of my macbook's spec, does anyone know why it is showing an error message?!

Thanks!
