Help! Long story, but the Reader's Digest version is this: I just switched from PC to MAC. I have always had good luck with SanDisk flash drives, but can't get them to work on my iMAC. I removed the passwords on my flash drive using my old PC, but couldn't get them to work on the iMAC. So, I bought a new 8GB flashdrive. Same story. On the PC it automatically asked if I wanted to create a password. Not on the MAC. It just sits there. It's like my iMAC is ignoring it. Thanks in advance.
