Resolved 2006/2007 Mac Pro (1,1/2,1) and OS X Yosemite

[GuitarNut]

8GB is plenty big. The whole installer completely setup is about 6.5GB.

The BaseSystem.chunklist is a hidden file located on the InstallESD.dmg:

BaseSystem.DMG is only a 478.7MB file. Most of the installers data is held in the Packages folder which is 4.61GB.

I assume it didn't overwrite the boot.efi?

It did not overwrite the boot.efi.

About Public Beta 5…

It was expected, but thankfully the update (OS X Yosemite Public Beta 5) downloaded and installed without any hiccups on my Mac Pro 1,1 with OS X Yosemite and Public Beta 4.

And one more thing…
When I updated my Mavericks installation, iMessage just worked effortlessly.

Great work Piker-Alpha, standing on the shoulders of Tiamo!

"silly" boot efi oct 7th

Can someone please upload the "silly" October 7th boot efi. I don't have time to compile it.

 

[TylerL]

I'm running Yosemite on a MacMini 2,1 using the boot.efi posted early this morning.
With the 64-bit beta graphics drivers installed, it's surprisingly usable! I even got a YouTube video playing smoothly.

 

[Snowleopard8]

Alright, not sure what's causing my MacPro2,1 to reject it. Everything loads and once done selecting language I get a message "Could not install in your computer".

 

[wwanthony]

This is wonderful gentleman. Thanks to all and Mr Pike. I did not think we would get there so quickly. All is running well on my 1.1 -> 2.1. I do have a supported MacBook Pro, so I simply installed GM 2.0 over a clone of my Mavericks System (my Home directory is on a separate Raid by itself) on an SSD. Copied the boot.efi. Rebooted. No worries......

I am not getting a boot screen. No iMessages....but I have not made the call to CS yet. I have a flashed HD5970 installed.

Here is the most recent (silly) build.

Working fine with GM2.

Sorry to have missed, but what's the deal/benefits to this 'silly' boot.efi?

I'm damned to having to borrow my MacBook Air to my sister for a few days, so I'm pretty much out of hope if my Mac Pro 1,1 and Yosemite boots acts up ^^

HDMI Audio GTX 570

So this is way off topic but I can't seem to find any solution or help anywhere. I have been following another thread on here that has a kext to enable HDMI audio with my GPU which worked up till 10.9.2. After that it stopped working. It does however work when using Clover or Chameleon with Yosemite. I cannot figure out why it will not work with 10.9.3+. I have kext-dev-mode=1 set right now in the boot-args while using the boot.efi which allows it to get past the invalid signature and load but it still doesn't show up in the sound preferences. Since I am using a non-flashed PC card I can't view the PCI section in system profiler to see if the audio portion of the driver is actually loaded. I have a feeling it works with Clover because of the SSDT file but I really have no idea.

Most people in that thread have an AMD card and it does work for them with 10.9.3+. Attached is the 1.1 version of the kext that the dev sent me.

I will be posting the sort of daily builds for those that want to try them. Generally they fix minor bugs or optimize the code. See the link in the previous post for the changes.

Hi all,

Lot of work already done, congrats !

Made a try with GM Candidate 1 for installer and Hennesie most recent "silly" boot.efi.

Installer boots correctly i get the following message:

"OS X Yosemite is already installed on this Mac."

Despite i'm using only one HDD on the MacPro that is a new 120GB SSD with 2 partitions :

1 x 8Go including the installer
and
1 x 112 Go empty for Yosemite to be installed.

Really do not understand what is happening

Have you got any idea ?

Thanks,

Update 1:

I've used the first installer i made for Yosemite 1 and changed original boot.efi with new ones, i get the same result when running this install:

"OS X Yosemite is already installed on this Mac."

I just updated to GM 2 and replaced it with the october 7 silly efi and Messages works haven't seen issues so far

I can't get that one to work with my AMD 6870 in my mac pro on yosemite, it works fine in Mavericks.

Quick note to say I succeeded to install Yosemite on my guinea MacMini2,1.

I'll continue work on adapting SFOTT this week-end and I've almost done it.
just have to add all extra steps needed for Yosemite.

many thanks to all for the instructions and I'll do all I can to have SFOTT working for Yosemite (I'm confident)

cheers.

Thank you for your help. I can add a success for Pike's boot.efi on my Mac Pro rev 1,1 / ATI HD 5870. Since it was not the last version, how can i test the last boot.efi on my Yosemite partition without having to reinstall everything ?

Simply download the latest boot.efi posted by Hennesie. Make a backup copy of the previous one in case something should go wrong. Then, replace the two occurrences of boot.efi with the latest version and reboot.

NB: In case you don't know how to do the above, I would suggest that you refrain from attempting any of this, or you could brick your computer.

 

[Mr. Zarniwoop]

I have been following another thread on here that has a kext to enable HDMI audio with my GPU which worked up till 10.9.2. After that it stopped working. It does however work when using Clover or Chameleon with Yosemite.

FWIW I've seen similar behavior with other hardware that only gets properly initialized by a Hackintosh bootloader. For example, my Mac Pro has a SAPPHIRE HD 4890 Vapor-X 2GB graphics card, a card never intended for an Apple computer. I flashed it with a Mac EFI firmware so it gets a boot screen, which works great, but it further requires the "exotic" 48xx graphics card patched kexts to enable QE/CI. Long before Chameleon's built-in graphics initialization features, I never found any of the early "injectors" to support this card properly. It still doesn't get properly initialized with QE/CI support without using Chameleon's "Graphics Enabler=Yes". Native booting with the exotic patch, including using tiamo's bootloader, results in no QE/CI.

Specific to HDMI audio, a while back on netkas I posted some DSDT edits to enable HDMI audio on a Mac Pro. I believe that's the source for HDMI audio patches used in Mac Pros with Chameleon and Clover. Maybe that post about HDMI audio DSDT edits can still help you find a better answer?

Thanks! Would love to see the new solution inside your installer.

Thank you. Then last version of the boot.efi works fine on my Mac Pro rev 1,1 / ATI 5870 HD - 1 Gb (genuine apple). Concerning the risk of breaking my system, I have installed Yosemite on a separate partition to test it. I don't want to use it as my main system for the moment

Then everything should be fine. If you follow the simple boot.efi replacement procedure, everything should be fine. In case something unexpected happens, such as the system being unable to boot, you have a failsafe system in place that will let you access your Yosemite partition and repair whatever harm done.

Yea it is just odd because the driver is loading but it is not showing up as a device and therefore not an option in the audio settings. Here is a screen shot:

When it works in 10.9.2 there is also and HDMI entry under Devices. I just don't know enough about IOPCImatch and what not to be able to understand what device/vendor and class codes I should be using to try and fix it. Even if it ends up being specific to my card.

Weird thing happened to me today that may help you:

I'd completed a fresh install of Yosemite PB5 and had no video over HDMI. Tried installing the HDMI Audio kext, just in case, but no change... No video or audio over HDMI, no devices showing in System Report even with kext-dev-mode=1.
Basically, I had no clue what was wrong at this point, as the same devices were working perfectly under Mavericks.

Now, here's the thing... Whilst researching the issue on my iPad, I was also pushing the Mac through some GPU benchmarks. Whilst the GPU was stressed, I happened to think of hot plugging the HDMI cable out of and into the graphics card... Bingo, picture and sound. Like I said, weird.

I'm guessing the GPU was in a low power state after boot; too low to push the HDMI signal over 10ft to the TV and Amp.

YMMV, but it might be worth a shot. FYI, I'm no longer using a GTX 570, I've swapped to a flashed HD7950.

Hope this helps!

Edit - video and audio have worked perfectly since, even after reboots.

WOW! With that boot.efi from your latest post, my Mac Pro 1,1 boots up to a MINUTE faster at around 50-55 seconds!

And my HDD isn't even that modern cache-wise (will get SSD when the time is right!). GREAT! <3
