Computer doesn't meet requirements

Hi there I've recently just purchased Premiere Pro and I can't open it because my computer doesn't meet the requirements?

"This computer does not meet the minimum system requirements for Premiere Pro CC. Please refer to the system requirements in the Help documentation for a full list of hardware and software requirements for Premiere Pro CC."

I've checked my Mac to see if any updates are needed and everything is up to date, but it's not working! Any suggestions? Thanks
