The procedureīut having only the iBook and an Internet connection, this is what I came up with:ġ) Download NetBoot for Mac OS 9 from this page on the Apple KnowledgeBase. Simply copying the System Folder from my Mac OS 9 Installation CD didn’t work, in case you were wondering. Or perhaps I would have just copied the Mac OS 9 System Folder from my Titanium PowerBook G4/400. I was not at home, otherwise I would have probably tried to install Mac OS 9 from another vintage Mac capable of booting into Mac OS 9, while putting the iBook in Target Disk Mode. However, I had forgotten that this iBook, a late 2003 model, can’t boot into Mac OS 9. I wanted to use a few Classic applications on my iBook G4/800 running Mac OS X 10.4.11, and I was prepared to install Mac OS 9.2 via an original CD-ROM I own. If it helps other people, all the better. I don’t know if this is the simplest or quickest method to install the components needed to use the Classic environment on a Mac that can’t boot from Mac OS 9 directly, but this is what worked for me, and it seems simple enough. I’m writing this post to be more like a personal reminder in case I find myself in a similar situation in the future.
