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

[vincenzo79]

Hello all,
sorry for the message but unfortunately, being very long, are not able to understand some of the things.
The guide to follow is that of this link ?

https://www.icloud.com/pages/AwBUCA...ite_on_a_Mac_Pro_1,1_or_2,1_-_Boot.efi_Method


Do you know if there are problems using the Nvidia GT 120 ?
I currently have 6 GB of Ram, do you think it will also need to upgrade the RAM ?
Thanks,
Vincenzo

The GT 120 is great and 6GB is enough

Hello,
thanks for the reply...
I hope the last question..
If I download the installer for the firefox browser from the Apple store this currently should be the version 10.10.5.
I wanted to know if there are problems using this version or do I have to download the version 10.10 ?
Thanks

I believe Yosemite is not in the Apple Store anymore...

 

[vincenzo79]

Hello Hall,

yes, I know that Yosemite is no longer available on the store, but with my Macbook Pro from the Apple Store still can't see it, I am attaching a image.

My only doubt is that currently the version that is downloaded is the version 10.10.5, so I wanted to understand if there are particular problems following the guide that was shared.
Thanks

It wil work. El Capitan is also possible but slightly more difficult.

El Capitan will require 12GB ram to do the install using the MacPro1,1.

 

[HAL2010]

Not if you do it with a hard disk and another Mac with El Capitan? Or am I mistaken? That's the way I did it with a Mac Pro with 7GB.

Correct, that's why I said using the MacPro1,1

 

[HAL2010]

Ha. Okay.

 

[vincenzo79]

But to me, personally, the El Capitan is not interested, I'm interested in that you can install Yosemite, which I find much better than EL Capitan, the important thing is that you have the possibility to take advantage of iMessage. For me it is fundamental.
Ok then I proceed with the purchase of the graphics card.

Here's the link to the installer image, Ive been pm'ing to people on request, I'm going out of contact for the next couple weeks so I wont be able to answer requests for the installer.

This is a Yosemite 10.10.5 image patched for both MacPro 1,1 and 2,1

https://drive.google.com/file/d/0B8L9ei8Z-RKUUlJ6dm52aWNSNHc/view?usp=sharing


This is a backup of the install disk after all the patches are applied, i.e. kext files, boot.efi, InstallESD.dmg, adding board id's for both MacPro 1,1 and 2,1 ..etc.. Basically all the steps that are in Hennesie2000's guide which you can read here,
Guide are done and in this image already using OSX 10.10.5

The only difference being I used an internal partition instead of a USB drive, and after following the guide and completing I had the installer on a small internal partition, I cloned this using SuperDuper!

My recommendation of the best way to do this is to mount the image,(Download the file and double click it wait until it mounts) then use SuperDuper! to clone it to a small partition on one of your internal drives once the clone is finished Choose that as your startup Drive.

Reboot to that drive and follow the installer as normal, choosing your preferred Drive/SSD as destination for the install.
When finished you should have a fully functional OS X Yosemite 10.10.5,
You can also update normally using the appstore.
You can also use disk utility I just found SuperDuper! simpler to use.


The partition Size you will need is no more then 8GB to 10GB, even though when you mount the image it will say capacity 22GB, thats only because I used a 22GB partition. If you Get info on it you will see there is 14GB free space.

The instructions may be obvious to some, but for people completely new to the process as I was at first it can be very confusing to figure out what to do and where to start.

oh man, thanks so much for this! this should be included in the first post at the top of the thread. I got yosemite 10.10 working on my 2,1, but couldn't get any updates to install successfully, finally stumbled on this after searching through this thread for days!

for any one else who can't install updates to yosemite this is the solution

First off let me say thank you to everyone on the form for the support found this information invaluable. So here's my problem. I have a Mac Pro 1,1 I used the SFOTT method to upgrade to mountain lion with the 2,1 firmware upgrade. All went well. I recently tried upgrading to Yosemite 10.10 with piker alpha's custom USB that was posted on this forum https://mega.nz/#!q1IRFJzK!GUinePUGF3jAAu3oUym-GHBC9doWRTU1p6nnkXkJFdQ At first I tried cloning my current mountain lion installation to a new internal hard drive and then installing the upgrade on that. Everything went successfully however the drive would not boot. Next I reformatted the drive properly and did a clean install. Everything was fine and it booted up properly. I went through all the prompts to get my OS X installation set and selected the data migration. I migrated all my data from my mountain lion installation. When it was completed it went to reboot but did not reboot successfully. I've tried resetting the PRAM safe mode, No matter what I try it won't boot up unless it's a fresh install. Is there anything I am missing? Do I have to do another fresh install and manually install all my applications and files over? My current system is a Mac Pro 2,1 with 2 quad core 3ghz intel Xenon cpu's, 16 GB of RAM, and a PNY GTX 610 graphics card. I've been working on this for three days it's driving me crazy. Any help would be greatly appreciated.

Just swap out the two boot.efi files again on your Yosemite install. Then make sure you install the PikeYoseFix before doing any updates.

Fixed. Thanks

My Mac Pro 2,1 Octa-Core is not displaying video after installing a 64-bit EFI and El Capitan.

So I followed a guide to get El Capitan on my Mac Pro 2,1 Octa-Core machine. Installed the 64-bit EFI, installed El Capitan, etc. Seemed like it all went fine. But the machine shows just a black screen now. I was using a AMD Radeon HD 6950. I then tried to put in a different card, an AMD Radeon HD 6850. Same result. I then figured putting in the original GPU that came with the machine would get it working. No dice, same result. I'm bummed about it, because the machine, while a little old, is still an absolute beast in my opinion. And it worked great before me messing with it. Now it's basically a big heavy, expensive paperweight.

Can anyone give me some direction on what to do now? While I'd love to get the machine working with El Capitan, at this point I would settle for going back to an earlier OS if necessary.

Original GPU should at bare minimum give you boot screen and allow you to choose start disk.

Let us know what you get holding "option" key

Not quite sure I follow but you will have to reinstall Windows.

I have Mac OS X 10.10.5 successfully installed. Two questions.
1) Can I install Windows 8.1 on Bootcamp an a separate HDD without it conflicting with the modified boot EFI?
2) Can I install Parallels without it modifying the boot EFI? (This was in the install instructions)

Neither of them use or will touch the boot.efi files

Hi...quick question... My MacPro 2.1 is running Yosemite and I recently update to the pikesyosefix, now all of a sudden my Mac won't shut down...its was running fine until I ran the script. Is this common and is there a fix?

Have you looked if any apps are still running and preventing shutdown with Activity Monitor?
Have you tried manually quitting all apps before shutting down?
I have not heard of this issue being caused by Yosefix and I ran it without any problem.
