Hello All

I have an iMac DV Special Edition 400Mhz PowerPC G3 (Graphite) with upgraded 640MB RAM from 2000. It shipped with OS9. I later installed OSX (10.2.8) around 2003 etc.

I had both OS9 and OSX all running perfectly. However, because my HD became full over the years with various software packages and versions affecting performance, I erased the entire HD and formatted it (Extended/HFS+ with OS9 drivers) to do a clean install of both OS9 and OSX. (Now before the criticism starts flooding in, yes, I know now that this was stupid and wreckless.)

Now I can only install OSX. The iMac does not recognise the original (orange cds)software restore or install discs that came with the machine. I even have the OS9.2 update disc (orange '9' on white cd) and the iMac does not recognise that either. I have repeatedly erased and formatted the HD to install OS9 in various ways but so far no luck.

Now before some of you start saying I should invest in new equipment, this is not my only mac, I also have a 2010 Macbook Pro. But I need to install OS9 on my iMac as well because I have some software packages that only run on OS9 eg SoundEdit 16.

So, is there a way to restore the original iMac software or set the machine back to factory default? You would think Apple would have covered this situation with a simple straight forward way to fix this. And I'm not the only one facing this problem as can be seen from postings on various forums. I am not familiar with Xtools or whatever it is called but I read somewhere there are 'packages' that restore the original factory settings. I also have the OSX Developer Tools cd that came with OSX. Is there any way I can use this perhaps to install OS9? Or is there is another way to install OS9? Please help me out. Any and all advice appreciated. Thank you.

The discs that came with your iMac should work. Otherwise you'll need a retail OS 9 disc.

It sounds like your optical drive has gotten weak with age - your original OS9 discs should work. Do they mount on the iMac when you are booted into X?

Try putting your MacBook Pro into FW target disc mode (hold down the T key during boot), then use the MBP as an external optical drive for the iMac DVSE.

Insert the iMac disk and hold down option when you start up the Mac. It should show you the CD to boot from after 5-15 seconds along with the internal hard drive. If it does not show up it could be the laser in the drive being only able to work with DVDs (hence why the OS X boot disk works) If thats the case and thats not uncommon when one of the lasers fail then reader50 solution is the best option unless you have a external USB CD/DVD Drive in the house you can use. I like using the OPTION key option when you are not sure about the computer seeing a disk because unlike holding down C, it actually lets you pause and see is the computer actually seeing the CD.

You might be able to do a target disk mode install from your newer mac too...

You might be able to use the new Macs DVD drive over firewire.
I have plenty of more important things to do, if only I could bring myself to do them....

Wasn't there an open firmware update on those old macs to support something about OSX that killed installed certain older versions of OS9 (or 8.5 even)? I think only OS9.1 will boot an older G3 iMac after that update.

Truthfully, you could look for OS9 on a t*rrent site, but that might be consider morally ambiguous, since you already own the OS9 license, but it just won't boot.

Zipped up copy of OS 9 would work IF the right enabler is in the system folder.

This one? It does indeed require Mac OS 9.1
iMac Firmware Update 4.1.9: Information and Download

I have a Mac OS 9.2.2 disk image at hand since it is the only one able to boot up on my Mac OS 9 capable Power Mac G4 MDD 2003. As far as I can tell, it might work only with these Power Macs. Does anyone know if it might work with that Graphite iMac DV.?

You really need the retail version of OS9.1 unless you know how to modify the computer-specific checks built in to the discs that came with other powermacs. A little searching and you might dig up how to modify that disc and burn a new disc that could boot your imac.

Thank you all for your suggestions.
Eriamjh is correct about that firmware blocking OS9 installation. Yes, I'll have to a bit of digging.
I have the OS9.1 cd as well but the iMac does not want to recognise the installer at all.
Athens, any clue about the right enabler?

Years ago I did manage to get the required new firmware onto a blue iMac, so I know it can be done!
(but I don't remember the details, sorry.)

And this won't help you with the iMac, but you can run OS 9 under Sheepshaver, even on Lion. I love playing the old Shanghai II within Sheepshaver.

Plus it looks really cool to watch OS 9 starting up very, very fast on an MBP! The extensions fly across the bottom of the screen.
