Though the game says it’s for PC and Mac you better check your specs really good before installing the game because Maxis wasn’t kidding about what graphics cards are not compatible. I have two family members with Macbooks and they tried to install the Spore Creature Creator and they couldn’t get past the galaxy screen. An email from Maxis confirmed that the graphics card was not compatible. If you have a newer high end Mac with Leopard, you should be able to play.
These are the computer specs that did not work:

The read me file from the game contains the following about Macs:
