Ok, I got my hands on a Mac G3 and it has 9.2.2 (clean install) on it. I have the OS 10.4 install CDs (four of them) and want to upgrade.

Is there anyway of mounting the .dmg files inside OS 9.2.2 and installing rather than from boot? (similar to a 9.x upgrade)

- Also, does 10.4 also include a os9 install as default? or has that been fased out. I am still new to mac but figuring out things as I go.

Late,

Short, practical checklist and gotchas for upgrading a G3 to Tiger (adds to the replies above):

First, confirm exactly which G3 you have. Tiger only runs on PowerPC G3/G4/G5 machines that meet the hardware checks (built‑in FireWire, minimum RAM and HDD free space), and a few very early/newer "odd" G3 models were dropped from official support — some people used XPostFacto to install on unsupported Macs. Also check whether the discs you have are the retail Tiger DVD (works across supported PowerPC Macs) or a model‑specific restore disc. (apple.com)

Prepare the machine and drive before you try to install: back up the OS 9 volume (clone or copy), update any firmware your model needs, and plan to reformat the installation target as Mac OS Extended (Journaled) if you need a clean install (Disk Utility is the right tool). Leave at least ~3GB free for Tiger (4GB if you’ll add developer tools), but aim for more and add RAM (512MB–1GB) for usable performance. (flylib.com)

If your only files are .dmg images: don’t try to mount and run them inside Mac OS 9. Burn the .dmg to a blank DVD (Disk Utility or hdiutil on another Mac will do) and boot the G3 from that disc. If you don’t have a burner on the G3, use a second Mac and FireWire Target Disk Mode to restore the DVD image or copy the installer onto the G3’s drive. Note: target‑disk methods need FireWire and won’t work on models that lack it. (flylib.com)

Quick workflow:

  1. Identify model/serial (use About This Mac or Apple’s model lookup).
  2. Backup/clone OS9.
  3. Ensure disk is Mac OS Extended (Journaled) and has free space.
  4. Burn/restore the Tiger DVD image or prepare a burned retail disc on another Mac.
  5. Boot from the install media, install, then immediately apply the 10.4.11 combo update. (support.apple.com)

This expands on ’s pointers: verifying model and preparing media/format/firmware will avoid the common “disc won’t boot on this machine” problems many G3 owners hit.

No, OS X has to be installed while booting from the CDs, in your case.

Classic (as OS9 has been depricated to) is not installed as standard with Tiger. However, since you already have 9.2.2 installed on the Mac, OS X will be installed "over it" (it doesn't interfere with the 9.x install at all) and you can use your existing 9.x install as Classic. No need to reinstall Classic.

Probably. But if you want a better chance of people actually replying, you may want to read the first paragraph of this:

>i have an mac book 10.4.8 and my son has completely locked me out f it and now its askine me 4 a admin passwrd
The only way to fix this is to have your OS X installation disk. (Well, there are some horrible ways to do it without the startup disc, but since you're a non-techie, I won't suggest it.)

>what i can do 2 get it off
Reset the administrator password. Once you've found your OS X installation disc, the rest is easy.

  1. Start up your MacBook, and once it's finished booting, insert the DVD
  2. Reboot the Mac
  3. Immediately hold down the 'C' key until you reach the installation screen
  4. Select a language, and then from the "Utilities" menu, choose "Reset Password..."
  5. Type in a new one
  6. Reboot the Mac again, and then you're all set

Funny how that post seems more likely to be the son locked out by his Mom than the other way around.

I was so sleepy last night I wasn't thinking very clearly... now that you mention it, I was pondering why a mom would have such bad writing. Crap.
