Well, it is confusing reading and sorting out but this is the way I see it.<br><br>You attach the firewre HD (FHD) to computer "A". You initialize the drive and install a system. Then you install your software applications, etc.<br><br>Now you attach the FHD to computer "B". Theoretically all the applications have everything they need to perform successfully on the FHD.<br><br>The question is: does the FHD system have everything computer "B" requires in the system folder to function? I don't have the answer but am wondering if this is what (preferences) the other guy was referring to?<br><br>Is a system folder for a rev. A iMac going to function as a woring system on a G3 blue and white? Just a far out example.<br><br>If this has nothing to do with the question at hand or the price of rice in china, pleas organize a firing squad and meet me in the back yard in 20 minutes.<br><br>Kate<br><br>

Kate in answer to your question, there can be a problem in moving a drive like that from Mac to Mac. Some macs require special little files, called Enablers, to work properly. Within the range of Macs that can run OS9 (let's say), there are some early ones with SCSI on the motherboard but no USB or Firewire, others (more recent models) with USB only, still others with USB and Firewire; it can be a mess. In theory it can work, assuming a model-specific enabler isn't required and all extensions required by both machines are in place.<br><br>John<br>[color:red]I don't need no steenkin' signature!</font color=red>
