in 10.0.4 my external scsi [yamaha cdr] was not even seen by my dt G3 but did allow me to mount data cd and even use the thing. Now we are in 10.1 and Apple system profiler sees it - one step forward. But it didn't burn with it and still doesn't. One step in place. Alas NOW it doesn't mount data cd's. One step back. Net movement. Nowhere. Everyone else supports scsi - MOS 9.x, Windows, Linux, open BSD - you name it, it supports it except for what appears to be poor sorry brain damaged OSX. Phooey - when will this be done right? Everyone jumps up and down and cries hurrah because with a cpu many times faster then many [450G4] the OS is finally fast enough to run.People tell me that scsi support in OSX is complete - it is all the fault of Roxio or Retrospect etc etc. If that is the case why desn't it work in Apple apps such as iTunes or Diskburner. And ask Apple? fuhgeddaboutit. Telling the loyal customer base is too dangerous, you know.
