I don’t know about the Eclipse OS specifically, but some gear does not like the extra files the Mac OS puts on a drive. the various “.” files and folders can throw off the hardware sometimes. I’ve had to take the card/thumb drive to a PC and clean all those up before an update would work. I believe there’s a tool you can download to your mac to clean up all those files and again — I don’t know if that’s specifically the problem the Eclipse is having trying to find that one file, but it may be worth a half hour of playing around to see.
