The SimCity Website has word that the Mac OS X edition of SimCity is delayed until August because EA and Maxis "do not believe it is ready for primetime yet," you know, like the Windows edition was. Here's word on the delay, which also outlines near-future plans for patching the Windows edition:

Hi, Mayors – today we are announcing that we are moving the release date of the Mac version of SimCity to August. We have made this tough decision because we do not believe it is ready for primetime yet. We want to ensure the Mac is a great experience for our players and that is why we are taking more time.

In the meantime, on the PC side, we are currently working on a series of multiplayer and multi-city fixes and improvements that will be available in Update 5. To give you a preview of what’s to come, see the notes below.

You can expect Update 5 to hit in a couple of weeks, so stay tuned for more info on that. In addition to Update 5, we are already beginning work on Update 6, which will focus on RCI improvements, a lot of which we’ve gathered from fan feedback on our forums. Once we have the notes locked down, we’ll release them in our “Currently in Development” thread, like we’re doing today with Update 5.

One final note for our Mac fans: As a sincere thank you for patiently waiting to play, we are going to extend the availability of the SimCity Launch Park (released in Update 4) to all players who have purchased the Mac version. Now you, too, can launch a Llama balloon. Because who wouldn’t want to do that? Thanks again for your patience and understanding. See you in August!
