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

[gpatpandp]

the possibility to choose the OS by pressing OPTION during power-on has nothing to do with boot.efi or the operating system installed on the machine.

it looks like all hardware is recognized properly.

I don't know about iMessage. I'm not using it on my Macs.

Other then the ever present/on going pain in the a$$ iMessage/FaceTime nonsense (Contact customer support blah blah blah), it works perfectly. Clover (or Chameleon) is no longer needed. Thanks much for everyone's hard work in getting this to work now on OS X 10.10 Yosemite.

 

[MacVidCards]

yes, just with the boot.efi replaced (okay, and without kernelcaches, I think).

Yay !!!

I look forward to testing. My 1,1/2,1 is a workstation during day but once he ends the workday I'll give it a shot.

Proud to see the GT120 256 Meg. I know where the rom came from.

Amazed you guys got this figured out so fast.

While your here and admittedly way off topic (sorry in advance) however you certainly would be the one to know...a few weeks back I picked up (on the VERY cheap) a reference model Sapphire ATI HD 4870 1GB GDDR5 and was able Flash it successfully with a rom file that 666sheep had formulated a few weeks ago for someone with the same model card. It works perfectly. My question...would it be a huge downgrade if I unloaded my overpriced Genuine Apple ATI Radeon HD 5770 in favor of the similarly "spec" flashed ATI HD 4870 ?

I've tried mikeboss' Boot.efi from Post #598 on my MBP2,2 with EFI32 - but no luck. Still the same result as in Post #572. The Kernel cache directory (/System/Library/Caches/com.apple.kext.caches/Startup/) is empty. It's btw. the patched PB3-Installer which I try to boot ....

Mine appears verbatim identical as yours. The only difference being that I used the latest Yosemite beta "Cocktail" .app edition and cleared the kext caches and now it boots much faster.

I'll give it a try tonight.

nice !

is there also a "non verbose" version or does that require more work?

i recall that Tiamo created both for Mav & ML.

Speaking of which....will this work on those?

Successfully booted using Mikeboss's boot.efi file on Yosemite 14A361c. This is on my test drive that isn't updated to the GM1 release yet. iMessage does not work but it is giving me that customer code that I need to call support with so it should work. Interestingly it is a different code than I have been getting when booted with Clover even though I am running a custom UUID that matches the one booted with this boot.efi, tiamos boot.efi or when booting 10.7.

Great work so far guys!!!!

**UPDATE**
Tried to boot back into my Clover setup by using the terminal command when booted using the new boot.efi and Yosemite and neither would boot anymore. I had to pull out the old Lion drive to get back into Clover/Yosemite. Right now I might stick with Clover because it fixes HDMI audio and allows me to use my monitors internal speakers and run audio out of that to my external audio controller.

Mac Pro 3,1?

Ok - slightly off topic, but the group of you in this thread has probably put more thought into this hardware issue than most other people on Earth...

I've run my Mac Pro 2006 via Tiamo as my primary workstation for as long as the Tiamo fix has been out. I have it updated to 10.9.5, and am using that brilliant little patch that replaces the boot.efi after each reboot. Flawless.
I also got this machine to boot Yosemite on a separate SSD using this thread.

So here is my new issue tonight - the old mac mini 2007 in our house died. I could probably repair it, but it is kind of a dog already, and has 3 external drives running off of it - so I am considering just replacing it.

So here is the question, let's say I look for another old mac pro. Would I be wrong to go for an 8 core 3,1?

I am thinking of swapping my 1,1 with the dead mini and shifting most of my drives and cards into the 3,1 - and poof, I have a Yosemite workstation!

What I don't know is if the 3,1 has any tragic flaw that I am going to live to regret. Any thoughts on this?

I know the 4,1 and 5,1 have some advantages - but they quickly get a lot more pricey. My 1,1 is 8 cores @3.0 and is enough power for what I do - no video editing here.

Thank you for any input!

If you are looking for something long term I would get the 4,1 or 5,1. They are more pricey but more power efficient, a faster chipset, cheaper ram (about half the price), hyperthreading... there are a lot of advantages. The 3,1 is basically a 2,1 with a 64bit EFI and 800Mhz ram. The 3,1 with dual 2.8GHz is only a few percentage points faster than a 2,1 with dual 3.0Ghz. Just my opinion.

something to play with for anybody feeling adventurous...

not sure if it will boot with kernel cache enabled. I didn't reboot yet I deleted the kernel cache before my first (successful) attempt to boot.

Holy cow mike!!! It really works

I'm booting with kernelcache, but I changed compression method to lzss. In a result black mode is only a flash on the screen, it doesn't even stay long enough to see the progress bar.

Holding my breath to see lzvn version. Maybe I could help in that but I don't know what I'd need to do.

Yeehaa. Booted into 10.10 flawlessly. The only Problem I have is ... my Gfx-Driver are not properly loaded (QECI-Patch Kext´s for HD4890 Card). Is there a way to enable kext-dev-mode=1 in the boot.efi? I think that is the problem.

EDIT:
Fixed it. Doing

sudo nvram boot-args="kext-dev-mode=1"

in Terminal ... reboot ... et voila. QeCi enabled. Mikeboss you are genious.

And the best ... I didn´t touch the default compression method.

Question to those who have successfully booted Yosemite into their 2,1. Did you guys create a bootable usb and then just changed the boot.efi in it? Because I tried it but hangs on the gray apple logo screen.

As far as I have seen it they booted the already installed Yosemite with the new Boot.efi instead of Chameleon/Clover.

 

[GuitarNut]

Success!!

I have it up and running as well.

I just booted into my Mavericks partition

Then I ran "chflags -R nouchg boot.efi" while being in the CoreServices Directory to unlock it.

After that, I replaced the boot.efi that was made in the CoreServices and the i386 folder and it booted.

This was on a Fresh GM Candidate install.

I actually used Clover to install it on the Mac Pro.

iMessage also works since I had already called for the Customer Code awhile back for my Mavericks install. Since this is the same computer now, not an injected form of it with Clover, it logged right in.

Screenshot posted. I edited my Serial and the UUID to protect the innocent

Hi,

So, you are using Clover along with boot.efi changes? I thought the boot.efi would eliminate the need of using Clover/Chameleon?

I only used Clover to install Yosemite via the method that is listed earlier in this thread.

After install I reset the PRAM (Command + Option + P + R) to boot directly into my Mavericks partition which overrides Clover.

After install is when I changed the boot.efi from my Mavericks partition and then I selected the 10.10 Start Up disk in System Preferences.

It booted up like normal without the use of Clover, just with the modified boot.efi.

You misunderstand what has been said. Several or all of the people who have been fiddling with Pike's boot.efi had already installed Yosemite using Chameleon or Clover. Reinstalling it using a second or third method is not required. All that is required is booting with the custom-made boot.efi bootloader INSTEAD OF the Chameleon/Clover bootloaders.

Once Pike's boot.efi is completed, a method will be devised whereby Yosemite installation will be achieved on old Mac Pros WITHOUT Chameleon or Clover.

Good news, I have Yosemite running on my MacPro2,1 without using clover /chameleon.

- Did a fresh install of Yosemite GM on an empty HD with the help of my MacbookPro5,2 17".
- After waiting 16 minutes to complete installation. After restarting, shut down laptop again and boot to Original OS and then I replaced both boot.efi using Mikeboss boot.efi.
- If your machine is not boot properly since installation of OS was disrupted, go in Recovery mode and select your original startup disk.
- Transferred HD to MacPro2,1, Voila!

Now, need to tinker with Yosemite since my wifi is not working at the moment.

Thanks all!

Congratulations!

Good idea - I've tried the same: cloned with Carbon Copy Cloner a already installed Yosemite from a supported Mac and exchanged only the Boot.efi with the new one.

Yosemite boots now on my MBP2,2 (late 2006, EFI32). Wi-Fi worked 'out-of-the-box'.

 

[Hennesie2000]

Finally had some time to revisit compiling the source code and I did have success this time around with Tiamo's source code. No hopefully I can be of more assistance.

 

[bulgakov]

thanks Pike and others

I was going to write about the clone way but somebody already did.
I have the public early release beta and it needed a special number to download.
I am not sure if it will work on more than one install but I will give it a shot
