After the success of getting Mac OS 10.9 Mavericks installed, I thought I’d get Mac OS 9 installed too.

Why you ask? Because we got a preschool CD-ROM at a garage sale and we’d like to check it out and see if Lily would like it. She won’t care how old it is.

Turns out, OS 9 is harder to install than I thought. I have an iMac G3 and a PowerBook 667 and both support OS 9 but neither would let me install it off an official install CD.

After some digging, I found the PowerBook’s original install disks and so I installed 10.1 and Mac OS 9. Once that was working I was able to put the iMac into target disk mode and install OS 9 on there from the install CD.

Seems like a lot of work, but I found it kind of fun. I also found all my old Mac OS install disks; well except for 10.4. That one is missing.

Now I have old and new Mac operating systems and can run most any Mac app. I even saw Internet Explorer on that 10.1 install.
