You can press CTRL+T to see the current status of dd. Note the 'r' added to rdisk3 which drastically improves write performance by telling dd to operate in raw disk mode: sudo dd if=RetroPieImage_ver2.3.img of=/dev/rdisk3 bs=1mĭepending on the size of your SDcard this may take a while. If you have an existing partition on the disk you may need to unmount it, otherwise you'll get a "Resource busy" error message when you try to write the image. In this case I can verify /dev/disk3 is my SD card because the TYPE, NAME and SIZE values are correct. Here's the relevant line from my output: /dev/disk3 The output shows a list of disks currently mounted on the system. You can do this by running the following command from terminal:
