The Pacific Image driver website link is here so you can download the latest version and I recommend that (downloading the updated version). It came with the scanner on a CD and I was able to install it on my Mac running 10.9.4. I purchased their professional edition in 2004 for $79.95 and have been receiving free updates all the way along and it has worked for every scanner I’ve owned and for those of you purchasing it now, it’s still the same price a decade later.
