Unfortunately some sad folks like to come to the forum not to help but simply to pick arguments for their own amusments.
No digitial still camera by any major maker requires installing drivers from a CD or DVD. None.
The same is true of many scanners and copiers too, in the hands of a knowledgeable computer user. People running older systems that they don't understand or know how to use will disagree, of course, if they choose to be argumentative. Personally, I ignore usch people.
The common causes for your issue are
1. A USB fault. That might be a damaged cable, an issue with the USB ports on your computer or your camera. Easiest way to check: swap the cables, try a different port, make sure your camera is on and charged
2. Try use a USB Card Reader or the Card Reader port on your Mac, if it has one.
3. Another possibility is that the camera card may need to be reformatted - you do this with the camera only.
