Whilst you might get it to run you are far short of the minimum system requirements for Photoshop CC which call for a GPU with 512MB dedicated VRAM minimum and 2GB dedicated VRAM recommended. The Iris plus has no dedicated VRAM, instead it shares the system RAM.
Thanks for swift reply. Would you be able to sugeest any Macbook which would be afficient to run 3d options?
I'm sorry I don't use Macs so can't really comment . Hopefully someone who does will chip in.
