Snow Leopard on Unsupported PowerPC Macs

@AphoticD
I keep reading about xxxx or USB on the old PPC G4 machines.
It's been my experience (both from having PPC and early intel macs with firewire), that they WILL NOT BOOT from a USB anything. It just won't show up in the boot picker. This machine has an empty drive so it needs to boot from an external something.
Please explain if people are getting their machines to boot up off a USB (drive, ssd or anything) as I have not been able to get this to work.

Correct. Many PowerPC Macs had USB booting disabled via the boot picker, but you can use Open Firmware to provide boot commands which will overcome this limitation.

Start at the Open Firmware Wiki here:

The Open Firmware Wiki

Figured I'd start another public resource initiative to encourage greater fluency with the underpinnings of a PowerPC computer, so that there isn't so much struggle and confusion just to boot an operating system (namely USB disks), check attached devices and resources, or perhaps even run system...

Just to chime in on this, unless you’re comfortable with installing an unsupported OS, you’re safest bet would be to install 10.5.8 on the iMac G4.

In my experience this has been the case of;
1. Install Leopard 10.5 retail DVD (or USB)

Installing from a FireWire drive works fine, and easier than USB (no need for OF hackery).

Can you name the models other that desktops that behave like that? Thanks.

From memory, most models had USB booting disabled via the boot picker, except for a handful;
  • iBook Clamshell 1st gen (sans-Firewire, so USB boot support was logical)
  • PowerBook G4 12" 867 (1st revision)
  • PowerBook G4 15" and 17" DLSD (final gen)
I have just about every model of PowerPC Mac laptop, so technically I could write up a list. Is there a model in particular you're interested in? I could give it a try.

Not really. I just wanted to try my own trick of cloning System drive block by block and checking whether it works over USB on 'problematic' models. I would then report back. I have several G4 PowerBooks, 12" 867 including

I know we are derailing the thread, but I observed something last night that I hadn't noticed before; I curiously pulled out my Pismo and plugged in a Tiger install USB drive, held the option key and as expected, didn't see the drive appear in the boot picker. However, after rebooting and dropping into OF first, then issuing the `multi-boot` command, the USB drive did appear in the boot picker...

I tried repeating this on a PowerBook G4 12" and had the same result, except the USB device showed up in the boot picker with the USB symbol rather than a name (typically "Install Mac OS X DVD"), but it still booted off the USB device.

I wonder if triggering OF, then dropping into multi-boot might actually trigger a USB boot device to appear "natively"... I'll try it on a few other models after work tonight.

Anyone knows if it can be set permanently?
 
For a note, anyone planning to install gcc11/gcc12 from my repo, hold on for a few days, do not do that. Macports suddenly switched the runtime to gcc13, which does not yet have needed fixes and is untested. Also, while installing gcc12 should still work, you will run into unneeded difficulties when using Macports, since the build system will try to force gcc13 (which will fail).

Anyone already using gcc11/gcc12, either install/update ports with sudo port -vn (which skips updating dependencies) or do not update anything for a few days.

I will try to handle fixing gcc13 soonish and then updating my repo and rebasing PR for old systems, but it may take 2–3 days. (I need to build gcc13, libgcc13, rebuild gcc12 and libgcc12 and make sure resulting runtime works.)

1. Well, it sucks, but we got nothing better, realistically. It also allows you to maintain a local repo and prevent any surprises. A bit tedious, but perfectly functional.

2. Old stuff – you mean tarballs? Portfiles do not vanish, you can go back in history on GitHub and use any older ports you wish. Of course, it may not build due to dependencies being updated to incompatible versions, but then you could, well, either fix it, or make a dedicated repo just to build something (if the resulting thing is supposed to be used in isolation, like, say, VLC).

GCC 13 builds fine on 10A190. I have minimized the patch to 3 lines.
Need to do some testing, but so far look good.

UPD. Okay, it has to be 4 lines, LOL. Otherwise once in a blue moon there is a linking error. I have updated the patch in my branch.

It varies across the PPC range. I can boot from a USB stick that's recognised at the boot picker screen without the need for Open Firmware fiddling and then install OS X on the following machines:

iMac G3/350.
eMac G4 1Ghz.
iBook G3 dual USB models ranging from 500Mhz to 800Mhz.

This is the method that I used to create the USB installer.

We really need a sticky for this subject...

I noticed this myself awhile ago.

However I personally haven’t ever been able to get Mac OS X booting this way. It always results in the dreaded circle with a line through it.

I found something amazing, LOL. Compare what 10a190 has:

/System/Library/Frameworks/CoreFoundation.framework/Versions/A/Headers/CFLocale.h
Code: 
CF_EXPORT const CFStringRef kCFLocaleQuotationBeginDelimiterKey AVAILABLE_MAC_OS_X_VERSION_10_6_AND_LATER;
CF_EXPORT const CFStringRef kCFLocaleQuotationEndDelimiterKey AVAILABLE_MAC_OS_X_VERSION_10_6_AND_LATER;
CF_EXPORT const CFStringRef kCFLocaleAlternateQuotationBeginDelimiterKey AVAILABLE_MAC_OS_X_VERSION_10_6_AND_LATER;
CF_EXPORT const CFStringRef kCFLocaleAlternateQuotationEndDelimiterKey AVAILABLE_MAC_OS_X_VERSION_10_6_AND_LATER;
This is identical to a released 10.6 and this is what 3rd-party software expects.

Now, the framework itself instead got this:
Code: 
nm -arch ppc -g /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation

0015a3e0 S _kCFLocaleAlternateQuotationBeginDelimiter
0015a3e4 S _kCFLocaleAlternateQuotationEndDelimiter
0015a3d8 S _kCFLocaleQuotationBeginDelimiter
0015a3dc S _kCFLocaleQuotationEndDelimiter

This is the result:
Code: 
dyld: Symbol not found: _kCFLocaleQuotationEndDelimiterKey
  Referenced from: /opt/local/var/macports/build/_opt_PPCSnowLeopardPorts_aqua_qt52/qt52-qtbase/work/qtbase-opensource-src-5.2.1/lib/QtCore.framework/Versions/5/QtCore
  Expected in: /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation

An easy fix will be to change the header, but then also everything which uses it should be made aware of the different symbol name. Or backport the framework, or rebuild from a newer source.

I remember from Leopard WebKit times that one can build a new framework binary that passes through the symbols from another dynamic library and just adds some additional symbols - and one can also add alias symbols.
I don't remember the details and which tool made this possible - most probably otool and/or dyld.

Oh, this is worth investigating for GCC too: currently we have to link to `libgcc_s` in addition to `libSystem`, because unlike 10.6.8, on pre-released 10.6 (likely nothing specific to PPC, but rather some version) a number of unwinder symbols are invisible in `libSystem`.

Do you know if we got everything to build libSystem from source?

All of a sudden, I have libdispatch built: https://ports.macports.org/port/libdispatch-legacy

UPD. Nah, ignore it, the header exists somewhere: https://opensource.apple.com/source...Kerberos5/Sources/include/kim/kim.h.auto.html
Just the build does not see it for some reason.

And it is not in Kerberos framework but somewhere else.

Code: 
In file included from /System/Library/Frameworks/Kerberos.framework/Headers/Kerberos.h:41:0,
                 from /opt/local/var/macports/build/_opt_PPCSnowLeopardPorts_www_arctic-fox/arctic-fox/work/Arctic-Fox-d47de016ca126fbb704adb4b49e862640f037c2d/extensions/auth/nsAuthGSSAPI.cpp:30,

                          ^
compilation terminated.

Possibly, a workable solution without overwriting system headers will be building against a later SDK (i.e. passing it as sysroot). That may introduce unknown complications, but on the other hand Macports does it here and there for Intel.

I remember from Leopard WebKit times that one can build a new framework binary that passes through the symbols from another dynamic library and just adds some additional symbols - and one can also add alias symbols.
I don't remember the details and which tool made this possible - most probably otool and/or dyld.

I wanted to write “Let’s ask Tobias” and then realised it is you :)

Perhaps GCC does that with `libgcc_s` on older macOS, I could try looking into their code.

After 4 years, yesterday i finally fixed my PowerBook G4 and decided to test the 10.6 PowerPC developer beta and after playing a bit with 10.6 10A190, I was able to develop a patch set to enable QE/CI for my ATI Mobility Radeon 9700.

All binaries are from 10.5.8 and I had to re-add the 9700 kexts and bundles, downgrade OpenGL.framework, QuartzCore.framework and CoreGraphics.framework. Both QuartzCore and CoreGraphics required stubs to load properly.

I think these patches should work for other AGP GPUs if combined with the correct kexts and bundles but I can't test since this PowerBook5,5 is the only PowerPC machine I have.

This is promising, I will try it.

Do you think we could get ATI 1900XT (i.e. PCIe) to be supported?
