Mac Pro 1,1 Yosemite Install

Mac Pro 1,1 Yosemite

Having let the dust settle a little from the initial release of OS X Yosemite, I decided to take the plunge and see if I could coax it on to my Mac Pro 1,1.  As many of you will know the original 2006 Intel powered Mac Pro does not sport the required 64bit EFI to allow either Mavericks or Yosemite to install via the usual method.

You can read all about the method I used to install Mavericks despite this limitation in this previous post:- Mac Pro 1,1 and Mavericks.  Using almost the same method as outlined in that post I have a working installation of Yosemite.

Mac Pro 1,1 YosemiteThere were only two things that I did differently.  Firstly, instead of installing on to a newly formatted SSD I decided to try the upgrade route and install on to my existing drive thus preserving all of my installed applications.  Secondly I used  Pike’s new boot.efi, (thank you to commenter Ralph Sampson for pointing me in the right direction) as I believe Tiamo’s existing version will not work.  More details and latest version here.

The install itself went smoothly and early tests indicate that everything appears to be working with the exception of Facetime which was also broken for me under Mavericks.  Not a huge issue, I may get around to calling customer support as prompted by the pop up window if I feel the need to see if it can be resolved.  I have experienced a few graphical glitches whilst using Lightroom 4.  I’m not sure if this is specific to Lightroom or a wider issue.  I’ll report back in due course.

(Update 18/11/14)

Installed the 10.10.1 update with no apparent problems.  I’ve resolved the graphic glitches for now by selecting ‘Reduce transparency’ in the Accessibility settings.  I’ve also been experiencing random wakes from sleep (wake for ethernet access is not enabled) along with the SSD that I have installed on a card in a PCI slot being randomly ejected.

One other problem that I have which I believe is more likely to be related to some new RAM that I’ve installed is the fans spinning up much higher than usual on wake from sleep.  I decided to try some cheaper RAM without the Apple approved heatsinks to bring the total system memory up to 26 GB.

  1. I was instructed to read this page, when I asked for help about my Mac Pro 1.1 running Mavericks. It seems that with either 10.9.3 or 10.9.5, the system recognizes only 8 MB of memory from the 512 MB my NVidia Quadro FX 4500 has. You seem to be very experienced in these issues, so any help you can provide would be greatly appreciated.

  2. Hi John, I can only recommend that you swap to a supported graphics adapter. With hacks like these certain problems are bound to arise with certain hardware combinations. I would suggest a Mac Edition ATI Radeon 5770 or similar.

  3. Mac Pro 1,1; ATI Radeon HD 5870 1028MB; 16 GB 800 MHz RAM 4@ 4GB, running as 667MHz; updated pair CPUs Intel X5365; four HDs; two DVD-RW. Also MacBook Pro 17”: from 2007 running Yosemite legitimately.

    I had converted my Mac Pro 1,1 up to Mavericks and followed the updates to their conclusion at 10.9.4. No difficulties. Back then I used the method of removing all the HDs from the Mac Pro but one, targeted that drive from a compliant Mac Book Pro running Mavericks and arrived at Mavericks on the Mac Pro on that drive, returning the other drives as well once OS was proven. So when Yosemite came out in GM and after the smoke cleared, I used the most recent form of Piker-Alpha boot file, a thumb drive and Hennesie2000’s excellent guide, that Mr. Zarniwwop had pointed out here:

    The approach worked well, took some time of course loading, and I have been running it for a couple of weeks without any problems. I have full use of my computer and OS. I recommend doing this without reservation to your old Mac Pro. Critical to have updated GPU or course.

    1. You have not indicated the GPU; it is critical though. ATI Radeon HD 5870 or 5770 or equal will work, for example. This is what I have been running for years on my 1,1, even before doing the hack-around.

      If you look back into this subject here, you will find info on the CPU requirement and recommendations. In my case, I stepped up to two quad Intel X5365 CPUs and had already mounted them before the hack-around. I think these particular CPUs are the most advanced a 1,1 can operate with. Since you are in the act of preserving your MP for years to come apparently, a CPU upgrade is a very good idea, even if it might not be required to run Yosemite via Pike’s Boot.efi.

        4. has the default Sata drives in it. Would like to go to a SSD boot drive. Any suggestions?

        Software: i have downloaded Piker-Alpha’s pre-patched Yosemite installer.
        My question is – After doing the hardware updates and ensuring things are ‘working’, would i be fine to just go straight to getting the Piker installer onto a new SSD boot drive and then bring up the MacPro (essentially skipping the mavericks step) or would you recommend getting the Hardware + Mavericks Step 1st and then go with the Alpha installer to ‘upgrade’ to Yosemite.
        You help is greatly appreciated in advance.

  5. I managed to easily install Yosemite on my MacPro 1,1, by using Piker-Alpha’s pre-patched bootable Yosemite installer:
    http://forums.macrumors.com/showpost.php?p=20537556&postcount=2184
    “that can be restored to a USB flash drive using Disk Utility (http://support.apple.com/kb/PH5848).
    This method, a fork of tiamo’s bootloader, uses a replacement native EFI32 boot.efi boot loader that thunks EFI64 calls from the 64-bit OS X kernel to the EFI32 firmware…
    Those who want to manually build their own bootable USB flash drive installer can follow the guide to installing Yosemite using the Piker-Alpha boot.efi.
    While this method is preferred because it’s a native EFI boot, there is some risk is that installing future Yosemite updates could overwrite Pike’s EFI32 boot.efi if Apple were to update the stock EFI64 boot.efi. This would be unusual, but it has happened in a few previous OS X updates and is now expected to happen again in the 10.10.2 update. If this were to happen, the system would no longer be natively bootable on a 2006/2007 Mac Pro until it had Apple’s stock boot.efi replaced with Pike’s boot.efi again…” (see http://forums.macrumors.com/showthread.php?t=1740775)
    It works flawlessly if you replace the standard graphics card (XT 1600 or GT 7300) with an ATI Radeon HD 4870 (like i did) or a 5870 etc.

    1. Using my USB drive set up to install Yosemite via Piker Alpha, I saw the kernel has changed. The file was dated for this download so that means trouble, unless P-A will continue to work and just needs to be reapplied per our method. Or will this mean that Piker-Alpha’s file can’t be reapplied and we need an update to it to get 10.10.2 to run? When I blithely installed 10.10.2 Combo, I was also stopped at my restarting monitor blinking forever in primary colors.

    -HD
    – Added a Apricorn Velocity Solo x-1 Card &

    -Video : changed to Radeon HD 5870.
    My plan is to install Yosemite straight to the SSD and boot from it.
    Can you pls. point me to the latest STABLE config that i can configure and have up and running on the SSD
    I have backed up the OS already.
    I have seen a lot of instructions around the net, but this forum seems to have the most stable set of instructions. However, the latest discussions around 10.10.1 and 10.10.2 etc leads me to believe that its sort of a hit or miss. i don’t have to be on the latest update. i am just trying to get to the latest stable build of Yosemite.

    one more clarification. i have this macpro and nothing else. so any setup to do the SSD to Yosemite is something i have to set up 1st and then take the machine down and switch to a SSD based boot (today its a ~500Gb in the macpro with the os @ 10.7.5).

    Thanks in advance.

      1. Rakneesh, the main challenge you have is getting a copy of “Install Yosemite.app” to build your USB bootable drive. Since your Mac 1,1 is not allowed to get it from the App Store and you don’t have a compliant second computer that would be allowed to download Yosemite installer, you have to get it from one of the many torrents. Search “Install Yosemite.app torrent”. Then build the bootable drive as per “Guide for Installing Yosemite on a Mac Pro 1,1 or 2,1”. Note we think you also need “PikeYoseFix.pkg”, linked just above, to subsequently get to 10.10.2. Go here for comprehensive discussion first. http://forums.macrumors.com/showthread.php?t=1740775

  10. Ha. I can’t seriously believe it’s that easy. I’ve got folders full of research about upgrading my Mac Pro 1,1. I’ve tried all the installer stuff: hackintosh Chameleon, changing the board ids and Tiamo’s boot.efi and blessing this and that, and couldn’t get a boot. In the meantime, I had installed Yosemite on an external disk drive for my 2008 MacBook Pro 4,1, just to see what it looks life (wife doesn’t like changes in her cages, she’s got a 2013 27″ iMac and still whines about Eudora), and upgraded it to 10.10.2 and then I read your article. “Wha?” I mumbled. Anyway, I thought I’d tried that. So I swapped out the original boot.efi files (backed up of course ) for the Pike boot.black.efi, and rebooted with the drive attached to the Mac Pro, and up it came, nice black screen, nice blue desktop, latest version. Of course, I still have the original GeForce 7300 GT video card (and the original processors) so it doesn’t really work very well, but it works! Anyway, this is just say thanks for the extremely useful and straightforward and simple approach. What do you recommend for an affordable video card upgrade (I’ll probably never replace the processors — that’s kind of out of my pay grade)?

Using a guide I found on Google it was quite simple to flash the 5770, altho’ I haven’t been successful trying to flash other video cards that Google searches say are supposed to work. If you check around you’ll probably find that the PC versions of the 5770 are relatively cheap compared to the Mac versions of the same.

I then unplug that Ethernet cable and plug it in to the other Ethernet connection at the back of the MP1,1, and all is well, for a few days anyway.

        Also, alternately, after both of the integrated Ethernet devices en0 and en1 have failed, I restart/reboot the MP1,1, and connect the same Ethernet cable to one or both of en0 or en1, I get Ethernet back as soon as the MP1,1 has finished restarting.

        And to re-state what I said earlier, I have numerous devices, iMacs, MacMinis, three or four Hackintoshes, a couple of PCs, my wife’s MacBook Air, a couple of computers running Linux, none of which have ever exhibited this behaviour.

  16. I ran into a wrinkle I hadn’t considered. As you know, just about any Nvidia graphics card will work with OS X 10.8 and above, but if it’s not flashed for a Mac EFI, you won’t see a “boot screen,” you won’t get a display until it’s actually booted. Well, fair enough. I thought I might put the old 7300 into slot 4, and use it at x8 (there’s a configuration for that). So I bought a cheap GT 610, passive, with a big sexy-looking heat sink, and I thought I could put it into slot 1 which is where it needs to go to get x16 speed. When it arrived, of course, I found that the mounting screws for the heat sink raise it enough (off the top of the memory cage) so that it won’t go into slot 1.

    It works, and the Expansion Slot Utility finds it, but I need it in slot 1.

      I then booted up from another drive, unlocked the new boot.efi, replaced it with Pike’s boot.efi from a backup, changed the start up disk back to the main HD and the updater picked up from where it was left and completed the update.

      I now have 10.10.3 running. So far no issues.

      1. Kudos for being one of the first to try the update. So it sounds like 10.10.3 rewrites the boot.efi. Did you have Pikes Yosefix installed?

      2. Thanks!

        Yes, the new update rewrites them.

        I did not use Pikes Yosefix, but downloaded these (forums.macrumors.com/showpost.php?p=20283936&postcount=1616) and chose the easy way for the big upgrade, and kept a copy of them.

        Note: After the 10.10.3 update fails, both boot.efis need to be unlocked using the Terminal first in order to replace them (rubenerd.com/tiamos-32-bit-efi-mavericks-10-9-2/).

        Good luck!

      3. I have 10.10.2 on my Mac Pro 1.1 running fine.
        Installation of 10.10 using the excellent pre-patched Piker-Alpha bootable yosemite installer followed by installing PikeYoseFix. Update to 10.2 painless, but had reservations about the 10.3 update. Looks like I will just have to give it a go.
        Was planning on using target mode to reinstall the boot.efi if things went bad. If boot not possible, would either use my recovery drive or put in my old OS HD in to reinstall the new boot.efi .

        Cheers.

  22. FYI – because I haven’t read this anywhere in here…
    I upgraded my Mac Pro 1,1 (flashed it so it now thinks it’s a 2,1 model) also:
    32GB memory
    3 internal 1 TB drives (left one bay open for eventual SSD)
    swapped out stock video card for a NVIDIA GeForce GT 520 1024 MB
    Pike’s .efi bootloader (with script for shutdown overwrite)
    and all is well in the world!

    One exception… Can’t get anything to show up under “displays” in system preferences? It reads the correct video card under “about this mac” and I don’t see any performance issues. Just wondered if anyone else had this issue? Also, has anyone updated their MP 1,1 to El Capitan yet? If so, anything we need to know?

    Thanks:-)

  23. Can anyone please give DETAILED STEP BT STEP INSTRUCTIONS on how to install Yosemite 10.10.3 on my 2006 Mac Pro 1,1 from Lion OS. Have a 5770 video card installed to use FCPX and Photoshop on my two 30″ Cinema Displays. I have a spare 750 Gb HD to use as the Yosemite HD.

      with the instructions that can be found here:

      Should do you.
      It is essentially a standard install, the patched version includes the alterations to the boot.efi so you do not have to do any terminal jiggery pokery. They you install the pikeYoseFix script (as mentioned on the instructions web page) which ensures the patched boot.fi is reloaded every time the computer reboots so an update that overwrites it does not break the machine.
      This advice comes with no guarantees of course, each system is made unique by its owner and all modifications are undertaken at your own risk. Back up all essential data before modification is always recommended.
      It worked fine for me however.

      1. So in theory, if I’m at 10.10.2 and I run any of the Apple Software updates, all I would have to do if it doesn’t reboot properly is boot to another drive where I could access the file structure and replace that boot.efi?

        A fresh install is one thing, but I’m trying to lock down a procedure for the incremental updates.

  25. Like others, I have tried to install 10.10.4 on a Mac Pro 1,1 with no success. It ran fine with 10.10.3 and I mistakenly ran the update on from the app store as opposed to updating from my Macbook Pro with the MP in target disk mode – temporary loss of sanity. But now I have tried to do a clean install on the MP with no success. Does the latest version of Pike’s boot.efi work on a MP 1,1?. I’m hoping I am just missing something but nothing is working – ugh… Thanks if anyone has some experience with 10.10.4 on a MP 1,1 or 2,1 (I have 3 of these machines that all worked in 10.10.3 but am hesitant to upgrade the 2,1’s until I get this resolved.

    1. Graphics cards are a problem as the standard cards provided with the original 1.1 are incompatible with the upgrades requiring the modified boot.efi.
      I got the ATI Radion 5770, there are 2 ways of going about this. A Mac version (more expensive), or to flash a Windows version (cheaper but more work). Mac is plug and play, I have not tried to flash the GPU and so cannot help there, but there are instructions available on the net.

      1. Not sure I fully understand what you are implying. You need the advanced graphics card for the modified boot.efi to work. An older graphics card does not add anything unless you are running more than 3 screens. Cards such as the 5770 must be in slot 1 as the PCI slots in the 1.1 are not all the same (check the specs for your model). Since you can run 3 screens of one 5770, what are you running that requires the addition of an older card and why would you want an older card instead of the newer one?

Even if i have an image i can setup to restore snow leopard.

It sure would be nice to know how to downgrade after the firmware and chip change. Because I wasn’t planning on putting the w3520 back in just to downgrade the firmware for snow leopard.
