I had an old Canon USB scanner sitting in my home office and had wondered how to get it working with my iMac running Mavericks. I also have an ancient parallel port Canon scanner and an elderly Fujitsu ScanSnap on an old WinXP Gateway PC. Whenever I wanted to scan something, I had to fire up the old XP box. There had to be a better way! I googled around a bit, and stumbled across VueScan. I downloaded the code (in demo mode, it puts a watermark on the output, but you can use all the features) and was amazed that it very efficiently drove the old Canon. At $40 for a basic license (cross platform, PC, Mac, Linux, and up to 4 systems), it was more than I was hoping to pay, but it got me a scanner with a lot of software functionality for less than buying new hardware. Plus, it appeals to my “green” side, trying to keep old electronics functional without sending them to the landfill. I knew I’d kept that old scanner around for a reason. I’m just beginning to play with the functionality of the software, it’s very full-featured. If you find yourself trying to bring an old scanner to life, or if you are just unsatisfied with the software that came with your scanner, check out VueScan.
Fujitsu S500M with Mavericks 10.9:
Other Fujitsu pages say the S500M isn’t supported. I installed this and it works again in Mavericks.
