I am new to Macs, only a few months now, and I wanted to se about scanning some old photos. I was checking out Image Scanner as it appears to do what I am looking for. Just basic scanning. I have an all in one printer and the scanner part shows up under Shared. So I select the settings I want for a photo, hit scan and I can see it scanning and there is a progress bar. However, once that progress bar completes it shows just 'Scanning...' but nothing seems to be happening. My scanner is not scanning anymore but it does seem like the OS is still processing the image. I did select to scan at 4800 dpi using millions of colors. Could this be creating a huge amount of work of it processing? And the printer/scanning is over Wifi which maybe it is slowing things down too. Thanks!
