PlayFirst today launched the Macintosh version of Diner Dash, a game which follows former stock broker Flo as she quits her day job and opens up a small roadside diner. The objective is to turn it into a five-star restaurant. “Diner Dash represents a new generation of popular downloadable games and is a perfect fit for the creative and inventive community of Mac owners,” say the company. “Mac users can now experience the original animation, fast-paced gameplay and compelling storyline that have made Diner Dash a number one hit.” Diner Dash is priced at US$20 and requires Mac OS X 10.2 or later.
