Hi. I have a Sanza ClipZip with rockbox. I used to use my pc to make .talk and .voice files until the PC started falling apart and I sent it to the recycling. No matter what I do, I can not get the Mac version to work. Everywhere I interact VoiceOver says unknown and everything in the menu is dimmed. Is this me doing something wrong or is RockBox on the Mac not accessible. Thank you.
