Re: Sim City Mac graphics issues on a very well equipped Mac Pro...

If the machine is actually good enough, run it with the more graphical OS, which at this time is Windows and Direct3D.  The two don't compare in this game.  You'll need Bootcamp and Window itself. 

If all you have is a Mac, then what? or is the nonwindows the mac?  Im sorry I'm not so computer smart.

Not sure what your asking really... You can run Windows on your Mac.

That's how to use BootCamp.

i basically want to know how i fix this without partioning my hard drive.  Or is that the only way until a patch is made to resolve the game issue?

What are you system specs?  Go to "About this Mac" and list the GPU (graphics card) that is the most important thing I'm concerned about.  Other good info is the Processor (CPU), RAM, OSX version, and Resolution if possible.

Have you tried setting everything to Min/Low with a low resolution and still no good?

i dont know how to lower the resolution.

Processor  2.3 GHz Intel Core i5

Memory  4 GB 1333 MHz DDR3

Graphics  Intel HD Graphics 3000 384 MB

Software  Mac OS X Lion 10.7.5 (11G63)

You and your tinker toy video don't get to do that until after you meet the OSX version requirement, 10.8.4
