A:AnswerEpson does provide the drivers and utilities for Mac OS 10.14x but notice that the date on the software is not current. My experience with an older Epson scanner and Mojave OS is that the drivers and utilites do not always work with certain software and that you might need a workaround.
A:AnswerNo, this scanner doesn't have any place to plug in a jumpdrive. But you can connect it via a USB cable to your computer or laptop, plug in a jumpdrive there, and transfer the images that way.
A:AnswerIt does not have a negative holder for4x4. There are some blogs about how others have overcome it. However, if you are looking for ease of workflow using this scanner with 127 film, I don’t think it will meet your needs.
