I believe that the absolutely-positively last (and latest and greatest) MDD install set is available via the MacOS9Lives Hotline server... and maybe someone else can guide you through that process?

I’m again, many miles from my base and have yet to setup my normal machine here... so if nobody else chimes in before, I can probably be a bit more helpful tomorrow. Sorry that I can’t be of more help at present.

In the meantime, you might try this one from Mac Garden:
https://macintoshgarden.org/apps/power-mac-g4-software-install-restore

I’ll check / compare this later tonight or tomorrow.

Good luck!

OR. There’s also MacTron’s Bootable Rescue CD & Disk Repair (Plus Version) w/ optional OS Install... if you only want OS 9.2 - but that’s also only on the Hotline server now as well. You can read more about it here:

However, the included download link there is now dead.

Hello,

I recently got a G4 Power Mac MDD and I would like to install Mac OS 9 on it.
It seems like this is the last model produced in 2003, on the back it is written M8570 (EMC 1914C). Unfortunately, the person I got it from wasn't the original owner and didn't have the restore discs.

I have a universal 9.2.2 install disc that it can boot from fine, but when trying to run the installer, it gives me the "this program cannot run on your computer" error. I read online that I need the specific restore disc that was sold with the mac because it was released after the last retail version of Mac OS 9. Where can I find it ? There are plenty of disc images on the macintosh garden, but not enough info to know which one to choose.

I'm asking specifically about Mac OS 9, because I know that I can use the regular discs for installing Mac OS X.

Greetings & welcome Nehalem501

Salut et Bienvenue.

Salut! It will be interesting to read your experiences.

Hello everyone

I found this forum by looking for information about my newly acquired G4 MDD.
I got this one because I wanted a Mac OS 9 compatible computer a bit more powerful than my G3 PowerBook. I also plan to try writing some software for this old OS just for fun.

I’ve been collecting older Macs for quite some time, I have a few 68K and PPC Macs that I tinker with during my spare time.

Be sure, that "Classic Mac Networking" is an important ressource and a joy to read, with all this knowledge and competence. I used it various times in the last – what two? – decade(s). Glad to see a v4 online now. Thanks for your time you put in creating and updating this "compendium"!

I did find LE 7.4 and 7.4.2 with some research on the internet archive.
Both are uploaded to the Hotline Server now.
