Fans who buy the game will be able to play it on Mac and PC and access their cities across both platforms, regardless of which version they own. Existing PC owners will be able to download a free Mac copy on release.
"In retrospect, our biggest takeaway is that we are lucky that SimCity has an enormous number of loyal fans," he said. "That first week after launch was really rough - an experience nobody wants to live through again.
"We've sold more than two million units, and the number of people logging in and playing is holding steady. SimCity is a success. However, underestimating demand in the first month was a major miss. We hope that the game and the service we've provided since then meets the fans' high standards."
Originally scheduled for a June 11 release, the Mac version of the game was delayed in order to "ensure it's a great experience".
SimCity update 7, which was released on August 23, gave players new scope to manage traffic and flow by enabling them to build bridges and tunnels using a new raise/lower tool.
