If you are referring to the System Software itself, the best source would be the install disks of that came with the computer (at least the G4 computers, I am not sure if Mac OS 9 comes with Intel machines or not). You can just boot into the Install disk 1 and choose to install OS 9 software on your computer. Or you could just insert the disk without booting into it and have the Finder show invisible files. You then do a search for “System Folder” on the DVD and drag it to the root level of your Hard Disk. The latter is my preferred way of getting classic to my HD. jg On 11-May-06, at 3:19 PM, Da Pen wrote: > Hello Everyone.
