The link to the pre-patched installer is in the very first post. Take the time to read through it. Also 512MB ram sticks shouldn't be any problem. I ran my Mac Pro with 4 of them and never had an issue.

Hello guys ! I just bought a mac pro 1.1 and I am trying to update it. Thanks for the massive amount of infos around here quite it can be overwhelming.
The mac pro have 2 GeForce 7300 GT VRAM (the original video card but in double, probably the previous owner wanted to have multiples monitors at the same time...).

My mac pro model :
http://www.everymac.com/systems/apple/mac_pro/specs/mac-pro-quad-3.0-specs.html

I am an audio engineer doing music mixing and recording and recently more audio mix for video media (movies, commercials...). I plan to work with this thing, not gaming.

It still rolls on OSX 10.7.5 and I just put 32 Go of ram in it.
Next steps are to :
- Upgrade the graphic card so I can install El Capitan and use this beast in 64 bits instead of 32...
- Possibly upgrade to 8 cores instead of 4. I read it was possible and not too expensive.

1st question : I understand that in order to install El Capitan, I need to use Piker's boot.efi and I have a couple videos and this tread to help me. I understand as well that my actual video card won't support 64 bit environment and that I need to upgrade it. What should I do first ? The El capitan upgrade with my current card and change the video card for a better one just after that or replace the video card and then do the El capitan upgrade ? Remember that I am still in 10.7.5.

2nd question : For my use, do you think a GeForce GT 120 would be enough (there are plenty of used ones on ebay for a reasonable price, around 120 $ CAD) or should I really go for a AMD Radeon R9 280/AMD Radeon HD 7950 (used on ebay for around 450$ CAD, another used at 300 $ on amazon.ca).

Thanks for your help !

My mistake - I was so used 512 RAM being an issue with El Cap i forgot it was OK with Yosemite.
[doublepost=1455910826][/doublepost]Hi, you will perhaps get better response over on the El Capitan on a 1.1 thread where you will also find almost all there is to know on running El Cap on a 1.1. As I understand it, it does run at 64 bit already but the boot efi is 32 bit - hence the need for a fix. If you look for posts by rthpjm you wont go far wrong as he has written some scripts following on from Pike's work to make this process much easier and to allow App Store updates without breaking anything.
Your RAM is fine and overcomes the first obstacle but I can't help much with video cards - I run an Apple 5770 which I updated a while ago and happily it works well. I also upgraded CPUs and added an SSD and it now runs great. Good Luck.

Dear All

I'm a macuser from France (sorry)

I have a 1.1 Macpro with SSD, 8go of ram and a pc version of the ATI HD5770 under 10.7.5

I try ones to up date with El capitain by installing it on an external drive with a supported mac then change the two boot.efi files and plug in the external drive in my macpro...

It work without problem in a first time,(boot ok) but after fives minutes on the desktop my macpro restart with karnel panic.
Now the restart is just after the login screen.. and it's every time

So i have tow questions :

- any idea of what should i do to fix it ?

- I'm perfectly ok if i have to go for Mavericks or Yosemite but i can't find an "appstore ok" version of both OS, so were should i download them/it ?


Cheers mates for any idea !
Have nice evening

[doublepost=1455956298][/doublepost]bonjour
pour avoir El-Capitan sur un mac pro 1,1 il faut 12 G° minimum et aucune ram de 512 m°. bonne continuation en espérant que cela te soit utile cordialement

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.

The 'Fix' is a script that checks whether the boot.efi in /Volumes/Yosemite/System/Library/CoreServices and /Volumes/Yosemite/usr/standalone/i386 are modded, or stock . . . if an Apple update decides to replace (e.g., "re-stock") said boot.efi's, the script notices the change, and re-copies the modded boot.efi back over the re-stocked boot.efi's



https://forums.macrumors.com/threads/2006-2007-mac-pro-1-1-2-1-and-os-x-yosemite.1740775/

More specifically (as noted--and written--by @Hennesie2000):

https://www.icloud.com/pages/AwBUCAESEIHvYxwJ7bfbQYZU8VqSphwaKdQEguSH2mGxgP5wk66iL6UtsMOX4MbJpAHpIQHV06hXsjj-VxPhjMWuMCUCAQEEIF5RLaPjoQEXqY55rowLfyEbKKz2FJoGHyk_VYi20E1F#Yosemite_on_a_Mac_Pro_1,1_or_2,1_-_Boot.efi_Method

The | is to allow one to get an install running as effortlessly as one with a 'Supported' piece of hardware could.

pre-patch is more than just the boot'efi's (see "_Method", above), and 'The Fix' does not allow upgrades, but "fixes" what the upgrades do . . . .



You can, and it will probably work (God knows there are way, way too many variables involved in these types of things to safely say "Yah; this always wurks.").

I'm writing these words from within 10.10.5 (daily-driver), even though I've run-through four or five handfuls of clean 10.11.x installs.

This is my current Stable, baseline environment, and I would not replace this with anything I have not fully tested.

As for your eBay purchase (and any pre-patched installer d/l from teh interwebs): you are placing a great deal of trust in the veracity of another's works, and you need to accept that you know not what you are getting, or installing (much like a .dmg "...from an unknown developer").

My choice is that which I create by-mine-own-hand from legitimate Apple sourcing, that it provides the degree of Trust I need to conduct my Business.

On the flip-side . . .

I trust Pike--and Pike's creations--as I've sourced the code since Tiamo first psoted it, and have inspected every line of the code. I understand far less than I would like (most of it's as good as a Chinese manuscript, to me), but I can and have seen all the changes, throughout. What I do know is that Pike's mods only make it possible for those of us with un-supported" hardware to avail ourselves of the latest OS'es.

Pike's a real fsck'n bad-as coder . . . .

Give the @Hennesie2000 guide a look-see, that it may educate on what you have in the pre-patch, and that you become confident in knowing further what these things are, and how they work.



You're welcome. Glad these thoughts are of some help.

"Forward..."

Hey splifingate! I'm back (work took over, big time) and finally able to get at the business of getting my Mac up to speed and I managed to get El Capitan 10.11.3 running smoothly with your help. I did rebuild my own installer flash and all seems to have worked great.

I had a Q; I updated to 10.11.3, and then manually replaced the boot.fi files using Terminal, but as I recall Pike had written a patch for Yosemite that replaced his boot(s) back in place automatically. Has there been a similar patch written for El Capitan?

And speaking of Pike, has any word come of his condition? I hope he is doing better.

Thanks again sO much for all your help! I could never have done it without your assistance and this forum's help in general, and of course Pike's efforts. What a great community, man.

peace & bananas | deg

My Yosemite partition has stopped booting. I get the black and white startup screen and then it switches to a grey startup screen and pauses there indefinitely.

I reblessed the harddrive but no cigar.

Anyone have any ideas?

Thank you! This worked perfectly for me.

I just bought a Mac Pro 2,1 3.0Ghz with eight cores off Craigslist for $100 which I think is a steal. I upgraded the ram from 6GB to 32GB and installed first installed El Capitain but found it unstable (random reboots) and then I installed Yosemite using your DMG and it works perfectly.

Thanks for putting it together.

Help!

It was working fine for the last four weeks. I did change the partition size on the drive it was on. Would this mess up the boot thing? Should I run Disk Utility from my patched Yosemite installer?

 

[Jayss321]

I can send you a download link to my installer with everything applied already all you have to do is use SuperDuper to clone it to a partition it only needs to be 8 to 10 GB,(I don't know if it works on a USB drive I dont see why not, but if you have a spare drive it will be quicker then using a usb drive)
It was created following Hennesie2000's guide doc.

Then Boot from it and follow the install instructions as normal, after install you will have a fully functional 10.10.5 Yosemite, that can be updated from the appstore without any problems.
Several people have used without any problems as long as it's a MacPro 1,1 or 2,1, when I was creating it I put all the info in for both.

Ok this is what I have, right now I have 2 HD of one being 200GB that has my OS 10.7.5 right now, and another spare drive I have thats installed as a Junk HD of 250GB, ( its used for spare files and such as Minecraft saves and backup saves nothing huge ), sorry for the late replay I'm my fathers care taker and can't get anything as in money right now so I have to use what I have. anyways I'm not the best at computer know how so ya have to bare with me. Let me know what needs to be done as well that you Deepwinter awesome job .

Also, this is for anyone here that has tried this and has gotten it to work, I have been told if this works the computer is slower as awhole is this true, I don't want to screw up my only computer I have in my life right now only to have it messed up for good. (I'm literary broke all I do is take care of someone that's it ( care taker ).

I have use the Pre-Patched instructions and have it running on our MacPro 1,1. It works GREAT! Thank you very much for that. Quesion...Is there a pre-Patched bootable Installer for El Capitan anywhere? Or, would I need to follow the instruction for making my own bootable USB but use the El Capitan Installer file?

This first post is usually updated with recent summarized information.


Two approaches that can be used to boot OS X 10.10 Yosemite on unsupported Mac Pro models:


Piker-Alpha bootloader (preferred approach)

This method, a fork of boot.efi boot loader that thunks EFI64 calls from the 64-bit OS X kernel to the EFI32 firmware.

Additional information about Pike's boot.efi is available at Pike's blog, Universum. There are two variations available, one with a legacy light grey background/dark grey Apple logo boot screen boot.efi that blends with the native EFI32 pre-boot screen (2008-2012 Mac Pro-style), and a new black background/white Apple logo boot screen boot.efi (2013 Mac Pro-style).

• The simplest install on a 2006/2007 Mac Pro is a pre-patched Piker-Alpha bootable Yosemite installer that can be restored to a USB flash drive using Disk Utility.

I have not seen patched El Cap installer but the El Cap thread has all you need to know. You will need 12gb of RAM if you are using the USB installer method and NO 512mb memory sticks making that up. If installing via another Mac and manually swapping the .efi files then the RAM isn't so critical.

Good morning,
I've downloaded this image.
I wanted to know some information. I imagine it must be changed by the graphics card. Right ? Recommended the ATI HD 5770 or the GT-120 to avoid having problems ?
After I changed the graphics card I can safely follow the instructions, and then starting with the installation, or you need to make changes to the image ?
Thanks,
Vincenzo

Hello everybody ! I just bougth a Radeon XFX for my mac pro 1.1 rolling on osx 10.7.5. I bougth it on ebay from someone telling that is was straigth out of his mac pro (so I figured out it was already flashed...)

This model :

http://www.materiel.net/carte-graphique/xfx-radeon-hd-5770-1go-directx-11-ati-eyefinity-52013.html

http://www.evertek.com/viewpart.asp?auto=79492&cat=69

Just plugged it, the computer is starting well and the fan of the card is active. But I have no signal coming out of the DVI ports. I know the computer is well started (I waited for 30 minutes).

I eventually want to upgrade to yosemite or el capitan.

I need help... I am not sure if it is the version of my osx (boothing in 32 bits) that cause the problem or something else...

Would you recommend :
-To return the card, get my money back and to buy one made by Apple ?
-To try to flash the card (seems like something quite hard...) ?

Thank you for your wisdom...

Here is the response of the seller, what do you think ?

Hi, I would recommend upgrading to at least 10.8, 10.7 will require modified kexts to get the displays to work with all outputs. As my Mac Pro is hooked into a 27 Apple Cinema Display I did not have a need to use the DVI port in Mac OS. I did however test the card in a PC before I shipped it out to you, all 4 ports worked. Definitely upgrade your OS, 10.8+ has native support for the 57XX family.

Get a card made for the Mac. Evidently, the card you bought was made for the PC and will not work correctly on the Mac.

http://www.macvidcards.com/ sells video cards for the Mac.

I bought an AMD Radeon hd 5770 video card on ebay for my macpro1,1 and it works great. I had to use a dvi to vga adapter to get a boot screen. It works with the dvi ports.

Hope this helps.

Been running Pikes pre patched image for a while now. Has been running super smooth since day one. I put a Mac ATI 5770 (1 DVI and 2 Display port) in and replaced the boot drive with a good SSD and running 12gb of RAM. I typically run 2 displays, DVI as my main screen and DP1 for projectors (running in a theatre setup). I wanted to add another projector, so total of 3 outputs form the 5770 and things got screwy. Can the 5770 run 3 independent displays with this config?

Ok I need a serious answer, I have been e-mailed ways to boot to a USB flash drive to install 10.10 OS X BUT, I'm still confused ( sorry I'm on a Mac Pro 1.1 2006. ) anyways I'm confused, is there a *file* or compressed set of flies I can download and just run the install? sorry if I'm being noobish here but this is the only computer I have right now. ALSO, I have a WD My Passport will that work as well?? I need to know thanks all.

1) Download the Pre-patched Piker-Alpha bootable Yosemite Installer from here:
https://mega.nz/#!q1IRFJzK!GUinePUGF3jAAu3oUym-GHBC9doWRTU1p6nnkXkJFdQ .

This is in the form of a dmg zip file. Double-click on the file after it is completely downloaded. It is about 5 gb, so it will take a while. It is not necessary to double-click the dmg file.

2) Make a small partition on your hard drive to use for installing the bootloader. Start Disk Utility. Click on the hard drive to be used for the installer. Click on the Partition tab. Drag from the bottom-right of the partition to resize the partition. Make it small -- about 10 GB. Click on apply. Click on the new partition. Click on the + sign below the left panel. Give the new partition a name, for example, "YosemiteInstaller". Click on apply.

3) Drag the Yosemite Installer.dmg file to the left pane of Disk Utility.

4) Click on Yosemite Installer.dmg in the left-hand pane. Click on the Restore tab. Be sure that Yosemite Installer.dmg shows up in the source drive window.

5) Drag the YosemiteInstaller Volume to the destination window. Be sure that "Yosemite Installer.dmg" is still in the source window.

6) Click on the hard drive in which you created the small partition. Drag the small partition, "YosemiteInstaller", to the destination window. Make sure that "Yosemite Installer.dmg" is still in the source window.


7) Click on the Restore button in the bottom-right of Disk Utility. It will take a few minutes for the restore to complete. As soon as it is complete, this partition will show up as a boot drive in System Preferences -> Startup Disk.

8) You are now ready to install Yosemite. Be sure that the drive you are installing on has a GUID partition.

9) Click on Apple Menu->System Preferences->Startup Drive. Click on YosemiteInstaller drive and then Restart. Your computer will restart with the YosemiteInstaller and start to install Yosemite.

10) As soon as Yosemite gets installed, download PikeYoseFix script from here:
https://forums.macrumors.com/attachments/pikeyosefix-black-pkg-zip.521961/
Run it and reboot Yosemite twice. This script prevents Yosemite update from replacing the boot.efi file.

9) Click on Apple Menu->System Preferences->Startup Drive. Click on YosemiteInstaller drive and then Restart. Your computer will restart with the YosemiteInstaller and start to install Yosemite.

10) As soon as Yosemite gets installed, download PikeYoseFix script from here:
https://forums.macrumors.com/attachments/pikeyosefix-black-pkg-zip.521961/
Run it and reboot Yosemite twice. This script prevents Yosemite update from replacing the boot.efi file.

11) Take a look at this thread on macrumors.com:

You can make that partition in one of the hard drives on your Mac. Make it small -- about 10 GB. Yes, the GUID partition can be made with Disk Utilities.
