Mac OS 9.x, based on Mac OS 8 was the final product based on the classic MacOS architecture. Like previous version, it lacks true protected memory or pre-emptive multitasking. MacOS 9 was abandoned in favor of of the Unix-ish NextStep/Openstep based Mac OS X. Updates to Mac OS 9 include 9.0.4, 9.1, 9.2.1, and 9.2.2. Mac OS 9.0.4 was a collection of bug fixes primarily relating to USB and FireWire support. Mac OS 9.1 included integrated CD burning support in the Macintosh Finder and added a new Window menu in the Finder for switching between open windows. A G3 processor with 128MB of physical RAM and OS 9.1 is the recommended minimum. (Although Classilla will run on OS 8.5, due to various bugs in that version we strongly advise updating to OS 8.6.).

Apple Mac OS 9.0 [Japanese] (HD Image)
If you intend to use hard drives larger than 128GB under OS 9, then be aware that you will need a Mac with an IDE controller that is 48-bit LBA compliant. What the hell is that, you ask? Well, it is the ability of the Mac to see the total number of heads, cylinders, and sectors of large hard drives. We have tested the following Macs and they can see hard drives of up to 500GB within Mac OS 9.2.2: Power Mac G4 QuickSilver 733, 800, Dual 800, 867, 933, and Dual 1 GHz with logic board 820-1342-B (QS logic board 820-1276-A will NOT work and peak out at 128 GB), and all Power Mac G4 MDD models are a go (except for the FW800 models since they will NOT boot to OS 9 directly). Also, Titanium PowerBooks of 800, 867 and 1 Ghz will work nicely. As far as the Mac OS revision, you will be stuck with Mac OS 9.2.2 only, as it contains Apple Drive Setup V2.1 that will be needed to format and partition drives greater than 128GB. We also recommend that you keep your partitions to sizes of 190GB or less or OS 9 will not boot and Norton Speed Disk V6.03 will not be able to defrag it. To clarify, if you are putting a 500GB in you Mac, simply break it into 3 partitions of 120GB for the OS, 190GB, and 190GB (format all volumes Mac OS Extended).
