Hi, I don't know how to understand the Sony Support page for Hi-MD Music Transfer: 1) it says "Minimum requirements OS X 10.3.9" - I have OS X 10.3.9. 2) It says that it does not work in environments where the OS is an upgrade to the original installed software - What does that mean? Virtually all 10.3.9 is upgraded, as 10.3.9 *is* an upgrade from earlier 10.3. There is no 10.3.9 for sale in shops. But actually, does it mean I have to use a Mac which has 10.3.9 pre-installed or what? My problem is that Music Transfer shows "Device/Media not connected", despite System Profiler shows the device. Which means: The Mac sniffs the MD, but the software does not. Any ideas what to do (if not upgrading to tiger)? Thanks a lot, Claus
