Sim City 4 will be coming to OS X soon. Aspyr, who is making the game, says it should be done sometime in May, but the way it's going, I seriously doubt it. As of right now, Aspyr posted these system requirements:
Mac OS X, version 10.2 or later
Power Mac G3/G4, iMac G4/eMac, PowerBook G4 (DVI model or better), iBook (32MB VRAM model only)
Processor speed 500 MHz or faster
256 MB RAM
1 GB of free hard disk space available
Hardware 3D acceleration required: ATI Radeon or NVidia GeForce card (32 MB VRAM or better)
I really can't wait until it comes out, but we'll just have to wait.
