So, as you may know, I sold all my PPC Macs but one, my iMac G4 700MHz. It was running Tiger, but after I heard the LeoRebirth dock issue would soon be fixed, I decided to upgrade to Leopard. The way I used to do this was to boot my iBook G4 (which, by Apple's requirements, supported Leopard) and into the Leopard installer and install on my iMac in TDM.

Now, with the iBook gone, I know of no way to install Leopard. I created an "Installer" partition on the iMac with the Leopard installer on it and tried to install it from there... only then was I reminded the machine wasn't technically supported. :p

So, how should I install Leopard now? I assume the Installer partition has to be modified in some way?

Thanks,
Henry

You can't boot Leopard from the DVD on your Blackbook and put your iMac in TDM?

The install is universal, so you'd be able to boot the iMac after it's done.

Use the fully updated PPC only 10.5.8 dmg on the web. Takes a few hours over USB to restore but it's worthit.

Does Leopard Assist work?

LOL I never thought of that! I forgot Leopard worked on Intels. :p This sounds like the thing to do, thanks!

There's a fully updated dmg out there? That would make things a lot easier! Where can I find it, Macintosh Garden?

So, is it an installer or just an image you restore to the hard drive? This iMac G4 can't boot from USB, but I can download the file on my Blackbook and restore it to the iMac hard drive using FW.
[doublepost=1500494479][/doublepost]Hm, been searching around, and I only found a few different sites with that file name, and they all just link to the MEGA download, which is broken.

If you could upload it that'd be great. :)

That's a good idea, but I no longer have an OS on this Mac. :(

It's an image to restore on your hard drive. Get a pendrive, format it as HFS+ (you can do it via Linux) and restore it on your HDD from the Tiger boot DVD (may work with the Panther CDs). I'll shoot you a PM later

I know they suggested restoring a hard drive image from the tiger dvd, just be prepared to wait okay? I did this once on my friends iMac G4. It took 8 hours to restore the hard drive image. Worth it? Of course. Felt the pain of USB 1.0? Definitely.

The image I have takes about 3-4 hours on USB 1.1 as it's stripped down :) It's worthit tho as I don't have any DL discs

I didn’t have that luxury. I installed 10.5.8 to my 2009 MacBook, added all the tweaks my friend needed, then carbon cloned the HD and restored it in the tiger installer.

I've been using a classic 15GB, 3rd gen iPod (with the row of four touch buttons) as a dedicated Firewire Leopard installation "Disc" for the past 10 years. The battery is shot, but plug it in and it doesn't miss a beat. Installation takes about 10-15 minutes. :apple:

There were one or two proposed, but I don't think they ever made it to market.

FW requires you to pay a licensing fee to Apple to use it and it never had the installed base of USB. Given the price/capacity ratio we've become accustomed to on USB thumb drives, I'm not sure if anyone would like the price of a FW drive.

True true. Quite amazing to see that no Chinese companies even tried it
