A CLOUDED LEOPARD:
Mac OS X 10.6 Snow Leopard on PowerPC

WikiPost last updated: 11 April 2022



OVERVIEW

We’re exploring how to run early builds of Snow Leopard on (later) G4 and G5 PowerPC Macs.

This WikiPost outlines testing methods to get a Developer Preview (DP) of Mac OS X 10.6 running on a PPC7400/7450- or PPC970-based Mac.

This is a user-editable WikiPost! Everyone testing on their own gear is invited to assist. Our collective work since the project began in April 2020 is extensive. We’ve still much more to do!

Many thanks to Julian Fairfax and @parrotgeek1, who got things rolling and who inspired @Larsvonhier to unearth this forgotten part of PowerPC versatility!

Join us on this adventure!

Snow Leopard Developer Preview 10A190

10a190B_0.png




WAIT, HOW’S THIS POSSIBLE?

During Apple’s product transition from PowerPC to Intel Macs, OS X supported both architectures, but a phase-out of PowerPC support neared. OS X 10.5 Leopard, on sale October 2007, would be the last major version retailed for PowerPC Macs.

When Apple supplied a first Developer Preview (DP) of OS X 10.6 Snow Leopard at WWDC in June 2008, its operating code prioritized Intel hardware but included a working kernel, Finder, and Universal Binary (UB) code for PowerPC Macs. Apple withheld comment on the UB nature of this DP, designated Build 10A96 (with a Darwin 10.0.0d1 kernel). At an early stage in Snow Leopard’s development, continued OS X support for PowerPC Macs was still on the table.

The following week, Apple clarified Snow Leopard would be Intel only. Nevertheless, a second DP in October 2008, known as Build 10A190 (Darwin 10.0.0d2), included UB code to run on PowerPC Macs and, like 10A96, a mach kernel compiled for three architectures — Intel 32-bit [i386], Intel 64-bit [x86_64], and PowerPC [ppc].

Though still PowerPC-bootable, 10A190 revealed just how much UB code, relative to 10A96, was gone and how less supported PowerPCs had become. By Build 10A222 (Darwin 10.0.0d3), December 2008, an all-new Finder, the first written wholly in Cocoa, was re-worked for Intel CPUs only. Although a “tri-architecture” kernel could boot on PowerPC Macs (namely, during startup “beneath” the grey Apple and loading wheel), it could not launch Finder. Internally, Apple may have maintained a UB fork as a plan B contingency.

After many more DPs, an OS X 10.6.0 “Golden Master” shipped August 2009. By then, most of Snow Leopard’s code base was Intel-only, but a handful of residual, “tri-architecture” components lingered. Knowledge that Snow Leopard’s earliest DPs could be used on PowerPC Macs was broadly forgotten.

In March 2020, @Larsvonhier read a tweet by @system2048, who posted a screenshot of Snow Leopard running on a PowerPC Mac. It was one of these 2008 DPs.

Ever since, the PowerPC Mac community have been learning all we can about the UB components in Snow Leopard — advantages, performance advances over Leopard, and areas where collective work will bring PowerPC Macs a big step beyond Leopard.



FAQ

What do I need to begin tinkering?
  • 10.6 Developer Preview DVD image (Table 1)
  • PowerPC Mac: G4 or G5 (Table 2 lists community-verified compatible PPC Macs)
  • kernel extensions & BootX carried from OS X 10.5 (10.6PPC.zip & BootX, attached)
  • external FireWire/USB drive
  • helper Mac able to run 10.5 or 10.6, out-of-box
NOTE: If you try a Server build, you need a license key.


Which builds may I test right now on my PowerPC Mac?

We’ve managed to boot completely into Builds 10A96 and 10A190. Table 1 has links for these.


And later builds?

Build 10A222 onward still has working UB code, but multiple barriers (kext conflicts, missing frameworks, Intel-only prefPanes, incompatible BootX, etc.) prevent PowerPC Macs from reaching loginwindow, WindowServer, or Finder.

We’re still looking for DP builds between Build 10A96 and the “Golden Master” (Build 10A432) — with especial interest to locate internal-only nightly builds. Should and/or when they emerge, we want to start sorting through them!


What may I expect?

If you’re new to our project, you should know that whilst less refined, Build 10A96 tends to run a bit more steady on PowerPC Macs, “out-of-box”, than Build 10A190.

[KEY DISCLAIMER: You must not expect this to behave as a finished version of Snow Leopard! It’s an alpha-level major work in progress. Features you take for granted on an Intel Mac running 10.6.8 or even 10.6.0 may not work well, correctly, or at all. You’re responsible for any damage or data loss to occur on your Mac. Here be a wild cat!]

In this thread, community members working with Build 10A96, despite it being older, find it to be a spiritual cousin of 10.5.3 (released a week before 10A96). In some ways, 10A96 appears to outperform not only 10.5.3, but also 10.5.8 (released three weeks before Snow Leopard went on sale). Build 10A96 still uses a Carbonized, 32-bit Finder and lacks HFS+ compression.

Build 10A190 behaves as a more direct ancestor of the final 10.6.0. Released soon after OS X 10.5.5, 10A190 runs on PowerPC Macs, but does so with less steadiness than Build 10A96. Apple’s work on removing residual UB code with 32-/64-bit Intel-only code becomes apparent here.


What’s this I hear about AGP video cards lacking hardware Core Image & Quartz Extreme hardware support? Is that true?

Yes. A long, boring, technical explanation is on #893.

In short: Snow Leopard’s development coincided with an industry-wide move Apple spearheaded toward a different video card driver programming language and computing standard called OpenCL (Open Computing Language). OpenCL, along with Grand Central Dispatch, débuted with retail 10.6.0. While Apple could have pressed GPU vendors NVIDIA and AMD/ATI to backport OS X drivers for AGP bus cards for hardware support in Snow Leopard, they didn’t bother because by going all-Intel, they could drop support for all AGP video cards (all Intel Macs use either discrete PCIe GPUs, integrated Intel GPUs, or a mix of both).

This means: PCIe video cards on multi-core Power Mac G5s (i.e., “late ’05” A1117) may be hardware-supported, but AGP video cards (on PowerPC Macs from 1999 to 2005) aren’t. Software-based support, however, allows a workaround. We have Fixes & Workarounds on how to do that.


Has anyone run benchmarks on “Clouded Leopard” to find whether it’s slower or faster than Leopard 10.5.8?

Yes: #1029.



GETTING STARTED: SET UP YOUR TEST ENVIRONMENT

  • Once you’ve downloaded and copied one of the DP installers to a bootable drive (i.e., via FireWire or USB), get the 10.6PPC archive (attached).
  • Use either the script 10.6 PPC.sh (you’ll need to open and change it to your volume name/path before running), or copy the kexts to the correct Extensions folder on your installer drive. Verify file permissions are set to root:wheel rwx r-x r-x (755), or use BatChmod.app (attached).

    [10.6 PPC.sh was prepped by Julian Fairfax, based on brief sketches from @parrotgeek1. Thanks for making it available!]
  • OSInstall.mpkg (attached) must be copied to /System/Installation/Packages (replacing original .mpkg). Verify file ownership and permissions! Another Mac running OS X is needed here. If all is done correctly, then this installer volume should boot on PowerPC Macs.
  • SHORTCUT: A pre-installed image of Build 10A190 is available (Table 1, “Fresh install image”). With thanks to Action Retro, we can present how to jump-start & skip manual patching steps. This image may only work on certain Macs.

NOTE: Core Image & Quartz Extreme hardware acceleration for all AGP cards in Snow Leopard isn’t possible. No updated drivers, kexts, frameworks, or patches to enable hardware acceleration is known. #893 explains why. CI/QE hardware acceleration for is confined to specific PCIe cards on multicore Power Mac G5s.

Test OpenGL with OpenGL Extensions Viewer 3.37 (OS X 10.2–10.6).

Some kexts/bundles are model-specific and may not load for your testing setup. Modifying them will have no impact. See last column. To know if a component is used by your Mac, open Extensions or Frameworks section in System Profiler. Components your Mac uses are shown here. Move kexts/frameworks via root/su only; rename old components in case you wish to revert!

1.6.0.x components may have higher version number, but bringing over 1.5.48.6 (Universal & PPC) components as a group may be needed to enable improved GPU support

PPC & Intel components in Leopard [L] are separate files — e.g., “GeForce” (for Intel) and “GeForcePPC” (for PPC); these are combined in 10A96/10A190 [SL] as UB, but extent of PPC support is TBD

REPOSITORIES
  • Apple Open Source Projects (AOSP)
  • Apple Open Source GitHub
  • MacPorts [You must build MacPorts from source. No “darwin_10.ppc” ports exist, though a handful are “darwin_10.noarch”; these will port install correctly. A workaround on the mechanics of Macports itself is proposed in two parts on #1113 and #1114. Another workaround: to add other ports, run “port -v pkg [portname]” on a PowerPC Mac running Leopard (and Macports), then copy and open those .pkgs on your PowerPC running 10A96 or 10A190 to install those ports.] Some are already .pkg’d and posted on #1111 and #1112:

QuickTime7.7.0 for Leopardinstall via Pacifist (whilst booted from another volume); manually move package components from inside QT 7.7.0 .pkg into their respective destinations. This requires either: A) terminal window, as super-user, to 'mv', or move pre-existing components (by appending something like “.old” or “.disabled” to filename); or B) changing old filenames from Finder on a different boot volume, as root & copy-drag components into place before rebooting SL-PPC

post-reboot, QT 7.7.0 should work. QuickLook rich media preview should be restored; some codecs may not work; recording with iSight FireWire works, but only after other video-component tweaks are in place (see Fixes & workarounds)
QuickTime7.6.x7.6 only time-expired; 7.6.4 intel only; use 7.7.0 for Leopard

Remote Desktop3.43.4 update, versus version bundled with SL-PPC (3.2.1), breaks WindowServer post-reboot: login works, but system hangs on blue screen; shy of reversing this installation (e.g., from a backup), you will need to re-install SL-PPC

I found that while on most of my machines OpenGL graphics accel does not yet work, with the tool OSX86Tools (that´s actually some kind predecessor of Kext Wizard or Kext Utilities that runs on PPC despite its name) QuartzGL can at least be activated and makes even slower machines more usable.

The exception is my Quad G5 that runs with all acceleration (ATI GPU kexts loaded, OpenGL, QuartzXtreme, QuartzGL, CoreImage by HW etc.) like a whirlwind...
I´m currently trying to get the right kexts loaded for other Macs as well with 10.6. PPC
Might also be a matter of the right frameworks as a package for Geforce FX5200..5500 suggests that I found for 10.6. (intel).

So 10A96 at least can go where no Snow Leopard has gone before (lame pun, I know). Awesome. Looking forward to updates and instructions!

Updates on instructions and some tools and bundles needed will follow soon (weekend coming ;-)
I´m figuring out where I could place the 7GB file for 10A96 for easy access. Tried MacintoshGarden but for some reason the web-uploader stops after some GB. I´ve already tried uploading the 10A261 version there, seems incomplete there now.

Hi Larsvonhier,

I'm also interested.
I also have a paying dropbox account do you think we can add it there?

Best regards,

For you and as a temporary storage place, why not. For permanent access for all I can still take care of other public places. If you like, send me your DB link to drop the build as a PM to my account here on MR. Will start upload tonite then.

Hi Lars,

Ok. I'll send you a PM as soon as I've it set up.
By the way I have several PBs and PMACs where we can try this :D ( I also have a quad G5
so maybe I can help you with the whirlwind tests )
Regarding you effort maybe you can talk with @JoyBed as he was trying to
do something similar in his case put 10.6 part inside 10.5.8.

And please as wicknix said do post this on the PowerPC subforum as it will
be good news for everyone.

Best regards,
voidRunner

I agree that this thread should be moved to PowerPC Macs. Link or no link, it will eventually be forgotten here. The former subforum however, is a vibrant one where threads are commonly revisited.

I also second that perhaps you could collaborate with @JoyBed, as he is currently attempting a similar project. With the efforts of two, the goal might be reached sooner, and maybe even in a nicer package.

Of course, the rest of us are also always willing to help where applicable. :)

Perhaps one of the mods will move it. Though this thread can technically go here as it does pertain to SL.. this subforum looks dead. PPC forum is really active. I've watched this thread though so regardless I'll be listening in.

Also, I have a lot of PPC macs and I would love to help test this out. I've also got quite a few SL capable x86 macs.

You've certainly got my attention, and when there's something to test, I have a (fairly low end) G5 that I'd love to see the results with.

Here´s a key for the server release of SL.
XSVR-106-000-R-LN2-VLQ-PRW-H6C-44L-XH2-P
As it is different from the one I´m using I feel free to share this one here for your experiments. I guess that Apple does not care any more about multiple installs with one key as this is clearly "abandonware".

Upload attempt 10A96 at macintoshgarden.org is now started. At my current DSL "performance" this will take a while, expect it to be up in the evening (MEST).

Hi guys,

So Lars has finished uploading the file to my DropBox account.
It's an ISO for the version which he got working with PPC.
If you want to download it send me a PM and I'll send you a public link for it.
I think for now and to test DropBoxe's capacity we should give it a few tries
downloading at the same time.
If everything goes well then I think I can share the link publicly.

@Lars Is this ok with you??

Best regards,
voidRunner

Sure, but it really hogs my space on dropbox, despite the fact that you shared the folder with me.
So I´ll leave it up there for a couple of days. At the same time, I´m still trying to upload it to macintoshgarden, but if it fails another time, I´ll have to find another solution. I also try to place it on my free mega account and will post the link when it´s done.

Hi Lars,

I changed it to another non shared folder so I think it shouldn't
show in you account anymore.
I'll send you the public link for you to use/test downloading.
I'm already downloading it to my quad so I can burn a DVD
with it or to copy to another machine to install directly to an
external disk and put your files on it and take it for a spin ;-)

Hi all,

So I've started tinkering with the installer.
Some good news is it's PowerPC/Intel binary so I think we can change it like
@dosdude1 does to enable it to "install" on unsupported machines like
our Powebooks and Powermacs.
I'm looking for the "instructions/description" dosdude1 made regarding the file
that needs to be changed to allow the install to run.
I think it will be as simple as what needed to be done in the DPs of Lion to allow it
to install in 32 bit x86 so it will be simpler to install without the need for an Intel system.
I'll keep you posted.

Best regards,
voidRunner

Can I put bootx directly on a currently running Leopard System?
