Apologies if this is something simple. Having only owned a iMac for 2 days, its all new to me, I am finding my way around. However, I have attempted to plug in a card reader so that I can read the cards from my digital cameras, but I cant get it to show up. If I connect the camera direct, it shows up and allows me to import the photos. Luckily, all the cameras I own use the same cards, so its far better to load the card into the reader rather than keep plugging in different cameras. Anyone any ideas how I get the device to show up,I have tried the 2 I have. Do I need a dedicated Mac device ? Any help appreciated.
