Can I run Da Vinci Resolve on an iMAC

I have an iMAC version 10.7.5 OS, 2.5 GHz Intel Core i5 and 8 GB 1333 MHz DDR3, but its graphic card is AMD Radeon HD 6750M 512 MB... I read that the ideal for Da Vinci its NVIDIA.

Can I run the software with this system or its not gonna work well?

You should be able to find your answer in the Mac Config Guide: http://www.blackmagicdesign.com/media/4 ... -10-10.pdf

If in doubt, try installing Resolve Lite. It's free!
