Informed user of Mac OSX, this scan is a real gas plant, while the inverse of the Mac philosophy. First of all it is necessary to scan the scan is disconnected from the USB. So if it is not loaded ... nada, since it is the charge mode! All scanned docs go on the SD Memory Card and then you must transfer the wi-fi or USB on the Mac. No driver to install like any printer or scanner, the scanner can not blow directly from other software like "Images of Transfer" (supplied with the soft MacOsX) as I did for example with my Epson scanner . Unable to scan directly with Readiris software provided with IRIScan since the driver is not installed! Records and poorly translated interfaces and dating! In short, everything the opposite of a Plug & Play device to scan docs. There is even talk of Readiris, garbage! for my part I use OCR Acrobat XI that is 100 times faster and reliable. Avoid. So in its carton and return to sender.
