For Mac OS X
This app works with: SheepShaver,

This is one of the earliest known Mac OS X 10.5 Leopard builds for PowerPC
This is actually compatible with G3 systems as long as you modify the supported machines plist file

Special thanks to xXkingtommy123Xx for providing me the rar file!

Mirror Link :

This is how to get it working on G3's and I am certain it should work just fine even if this is meant for another build (Based on some comments indicating for 9A321 which I am on a hunt for now):

EDIT: 6/9/20 : I am going to more than likely upload a pre-installed copy of this Leopard build for people who want to install it easily without installing it via the disc image etc etc. This should also help G3 users out and I'm also going to upload a version of the installer where it doesn't require the check so if anyone wants to install it on their own on a G3

EDIT: 6/10/20: I could not get PearPC or my iMac G4 to boot the installer, I tried the traditional USB install method for the iMac which normally would work but didn't, I have yet to make this attempt with the iBook G4 and G3 I have lying around, however I am installing it as a dual boot with Tiger & Leopard on said iMac G4 by using the "OSInstall" package file

To do this, go to the install media, then "System" -> "Installation" -> "Packages" -> OSInstall.mpkg, open that and it will open the macOS X installer


PowerPC: G3's (With Modification), G4's, G5's

I get ya'. Basically just am wanting the functionality of leopard with the interface of Tiger. Leopard, without CoreImage is close to unusable even on multi-processor G4s (about like trying to run Tiger on a G3 - nearly unworth the effort). But some of the things like QuickView, SparseDisk Bundles, and newer frameworks compatible with modern VLC would rock. Basically this has value if it is Tiger 10.4.12

None of the Shiny 3D pretentiousness served any purpose on any systems (Mac Leopard, Windows Vista, Ubuntu Unity) was all heavy-crap that nobody asked for - funny how the absolute rebellion against it was all this 'FLAT' design with no shine, or 3D at all - that we see in every modern system!!!

Mind you, Leopard was based off of Tiger, and the beta is no exception
Tiger itself had CoreImage, on Leopard if CoreImage is not supported I'm pretty sure on some later beta build of Leopard it would be labeled as "Software Rendered" or something like that, I know for sure on the final Leopard builds it was this

But since this is like Tiger, it's going to follow the same thing as Tiger, where if CoreImage is not supported, it will be labeled as "Not Supported"
I have no idea if it means it's just software rendered or what, Quartz Extreme is probably the most important in this case than CoreImage, and if it runs badly, I wonder if this build has QuartzGL that you could enable to improve some stability

I'd also question since this is kind of close to Tiger, that maybe somehow a modification could be pulled off to get it upgraded up to 10.4.11 while retaining the beta features perhaps
I know I'd have to try by renaming "10.5" to "10.4" in some file somewhere

Thanks so much for posting this. Have often wondered if maybe there was a Leopard version that was a bit lighter and still had the perks like compatibility with newer versions of VLC, Sparse-Disc Bundles and Dare I Dream - the ExFat Fuse addon. Worth a Shot. If it just doesn't have all the CoreImage crap would be worth having.
