Q: No "Scan To" pop up shows.  This is a brand new iMac.  thoughts? I find no "Save to" anywhere

OK. It's late and I blurted the question after an all day learning spree.  When I Scan, and I read the directions about the iMac, no "Scan to" pop up comes up, and there is no "Save as" other than the Details.  Why don't I have a "Scan to" pop up? I hope this illuminates the question above.
