Neat Scan Utility 1.3.1 Scanner is Neat NM-1000.

I can't answer your question regarding the comparison. Do you have an up-to-date scanner app? You may have to update it so it will work with your Mac's OS. Check the link below. I suggest you will be better served to contact Neat directly for assistance with your problem. Also, you should download and read the scanner's manual. That often clears up issues. Good luck.

Thank you for clearing up the issue. I suggest that you download and try the app VueScan. You can try it for free, but it will show a watermark. That goes away if you purchase it. I bought it and can recommend it. Check to confirm that it supports your scanner, though. It is a full featured scanner app. I have no association with VueScan.
