Making SimCity for Mac run at full resolution of 2560×1440 on a 27″ iMac

After spending ages on the phone to support, they finally came up with a working way of forcing SimCity for Mac to use the native resolution of a 27″ iMac.

Right-click on the game in Origin and choose “Game Properties”

Game Properties

and then type in:

-r:2560×1440

(You can change this to any resolution you like)

On my 27″ iMac it runs absolutely spectacularly at this resolution.
