I currently have Mac OS 9.1 installed on my G3 upgraded Power Macintosh 9600 (Tsunami Board) and am trying to update to 9.2.2 with OS9Helper. However, whenever I try installing the 9.2.1 patch it fails all the time. I extracted the Mac OS 9.2.1 update sit file with Stuffit Expander. Was I supposed to do that? What should I do?
