I have seen the threads: I have debugged usb..I have selected mass storage..(I have tried the optional 'ask when connected'). I have tried to manually mount the drive in disk utility but it does not appear there either. I have not installed KIES: it does not seem worth the trouble for a Mac ..the software is not even mac-compatible i believe? But i would like to update to froyo 2.2 so how to do that on a mac!!?? Should I scrap anything and everything of Samsung software? Any threads for a novice on how to do that? Is it necessary to 'root' thereby canceling the warranty....flashing the ROM downloading more software and other complicated things..... well..lots to consider!
