Hi, Cindy! My Epson 1670 worked in Snow Leopard, I thought they used the same driver, but can't be sure. Gave mine to Amber, so I cannot confirm. Having said that, I recently got a Canon LiDE 700F from Amazon for $120 with a Squaretrade warranty for 3 years for $17 and it works great. I think there is one model lower that also works well, but I bought this one so I could do some photographic negatives one day when I have time. (Insert massive giggle here!) . Good luck!
