while this scanner claims to be compatible with mac os x (i tried to use the scanner with both 10.3.8 and 10.3.9), it absolutely does not work. when i downloaded new drivers for it from the epson website (while using 10.3.9) it caused an unknown program to run all the time--it was epson smart panel--and i had to buy norton disk doctor software to fix it. the software can cause, in the words of the norton disk doctor, "major problems" on your hard drive. epson is absolutely fraudulent in their claims that this is mac compatible, and i am out almost $300 (scanner, shipping, norton software) because of their negligence. DO NOT BUY!!!
