I'll begin by saying that they're called minimum specs for a reason. Here they are again:
Here's a more detailed breakdown of supported video cards:
Here's Aspyr's official statement on what Minimum spec means:
Here's the RECOMMENDED specs:
So there you have it. Sources for these quotes are from here and here.
The next lot of information is from me, not Aspyr, and is highly opinionated but reasonably truthful nonetheless:
• If you have a MacBook Air - Civ5 is not for you, it was not designed for 3D games.
• If you have a pre-2009 MacBook - Civ5 is not for you, it was not designed for 3D games
• If you have a 2009+ MacBook - it will probably run but consider a MacBookPro or desktop next upgrade if you are serious about playing the latest 3D games.
• If you are still on Leopard - you have no excuse not to upgrade unless you don't have US$29. Leopard is no longer updated by Apple, you will never get the fixes you need.
• Do not expect Mac Civ5 and Civ5 via Bootcamp to have similar performance. They use completely different graphics drivers.

Here's Aspyr's official statement on what Minimum spec means:
Minimum System Requirements:
These are the very lowest possible specs you can have before you start to experience performance issues with the game. Being below the minimum system requirements can cause problems we cannot fix. If you just meet the Minimum Requirements, you should be able to enjoy the game on minimum graphics settings. We DO NOT recommend purchasing a game if you do not meet the Minimum System Requirements.
What if I’m just below the minimum specs? (i.e. 2.26 GHz v 2.4 GHz)
We DO NOT recommend purchasing a game if you do not meet the Minimum System Requirements. If you purchase a game without meeting minimum system requirements we will be unable to provide support from a customer care perspective.
What sorts of problems or performance issues can I expect if my hardware does not meet minimum requirements?
Performance issues could include slow downs, crashes, graphical issues, and not launching, among other problems. It is impossible to predict specific problems for individual users.
Here's the RECOMMENDED specs:
Recommended System Requirements
CPU Processor: Intel Quad Core
CPU Speed: 2.6 GHz
Memory: 4 GB RAM
Video Memory (VRam): 512MB
