I have just bought a C200 camera. I also bought a micro SD card for storing images.

When I insert the card I get a message that the card is not formatted

Will someone please explain what I should do as all previous cards for other appliances have not requested this.

I have a iMac and I understand that Apple uses a different format from Microsoft (external hard drives have to be formatted differently).

Can I format my card on my iMac and if so how?

Thanks
