Sixty Four On Thirty Two (SFOTT)

Yosemite / Mavericks / Mountain Lion on Unsupported Mac

This page is dedicated to Sfott,

this “little” piece of code I did to automate the creation of USB key with the boot.efi from Tiamo’s of MacRumors.

This script aims to prepare a USB or disc media for Unsupported 32bit based Macs that are not eligibles for Mavericks or Mountain Lion.

Cette page est dédié à Sfott,

Ce “petit” bout de code pour automatiser la création d’une clé USB avec le boot.efi de Tiamo’s de chez MacRumors.

Ce script a pour but de préparer une clé USB ou un disque dur pour certains Macs non supportés 32bit et qui ne sont pas éligibles à Mavericks ou Mountain Lion.

    I installed 10.9.0 on my MacPro 1,1 using SFOTT. Worked great. The 10.9.4 combo update installed and I re-patched the system disk, but it did not work. The system disk would not boot. I used 1.4.4 of SFOTT.

    I’ll reload 10.9.0 and get the incremental updates from Apple’s website.

    Thanks for all of your hard work.

    • Great work! One correction on the English instructions: when re-patching after updates the confirmation menu says ‘re-patch again’. This should be simply ‘re-patch’.

      En français c’est comme dire ‘re-correctif encore’.

      English speakers will assume the patch was already applied at the confirmation prompt.

      Un petit problème, mais déroutant au premier abord.

      This may be what gave David problems.

      Thanks for all your hard work on this!

    • Avatar Lee says:

      Hi David or anyone that can offer help or a link if they have come across my issue.

      It seems OEM may be on hols and i really would like some help im in the same boat as you Mac Pro 1,1 2006.

      I have my usb done i have a spare drive for a clean instal i even ran it and had 10.9 running on my 1,1 but i cant understand the steps on how to update ie 10.9.1 to 10.9.2 to 10.9.3 to 10.9.4.

      I used the app store to update to 10.9.4 and it will not boot back into that OS. so i wiped it start again.

      So i can install 10.9 simple but then how do i get to 10.9.4 the instructions are not clear or maybe its me reading them which is the case as many others have already updated.

      What i want to do is this.

      1, install 10.9
      2, update to 10.9.4
      3, check play with for a few days as i only have 7GB of ram and want to make sure of the affect on CPU and RAM.
      4, My now main HD 500gb running 10.7.5 wipe ready for a clean install
      5, Main HD partition for 10.9 say 400GB and 100GB for boot camp windows, would also like to starting using and familiarising myself with Linux so maybe 400gb= Mavericks 60Gb=B/Camp win and 40GB=Linux

      What im not quite getting is the updating of SFOTT to version 1.4.2 to update to 10.9.2 when i already have version 1.4.4 when i made my usb boot disk.

      Any help much appreciated, just need a nudge in the right direction to be able to update and whether or not i can go 10.9 straight to 10.9.4 if so which update to use the combo or app store.

      Thanks in advance to all also OEM for building this and of course Tiamo

      • oem oem says:

        Hi Lee,

        Apologies for the delay….

        if you did not made the update to 10.9.2 yet and plan to go to 10.9.3 or 10.9.4 directly, then yes you’ll have to repatch.

        Repatch and 10.9.2+ update will change boot.efi

        – Update from 10.9 to 10.9.2+ (10.9.2 or 10.9.3 or 10.9.4) from the Mac AppStore.
        – Let it reboot you’ll have a failure, it’s ok.
        – Then either from a SFOTT Key or simpler from another system (let’s say 10.7.x), run the SFOTT script again and choose re-path don’t forget to previously choose the system to repatch in Settings.
        – repatch then reboot.

        Hope I’m clear enough

  2. Avatar Lee says:

    Im just getting round to installing Mavericks on my 2006 mac pro 1,1 i know im very late doing this.

    Anyway open to anyone, can i go straight to 10.9.4 or should i go 10.9.2 10.9.3 10.9.4 anyway whats the best way a link will do if this has already been answered, if so sorry in advance for asking the same question.

    • oem oem says:

      Hi Lee,

      I’m really sorry to answer so lately. you can go on straight to the last version of 10.9.4, this will save you hassle of the the combo update needing re-patch

      • Avatar Lee says:

        Cheers OEM

        Look I’m happy you have responded, your doing this for FREE so thank you very much for all your effort, Im not in work at the moment but will remember, when to drop a little donation in when i am.

        Just to clarify i install 10.9 using the made boot key.
        Then download the standard 10.9.4 update NOT the combo.

        I do not have to patch or run the key at any point between 10.9 and 10.9.4 I think that im over thinking it because its to easy.

        Thanks again will give it ago at some point in the next day.

        • oem oem says:

          Hello Lee,

          I’ve not made all tests but If I’m correct :
          – You will HAVE to REpatch until you reach 10.9.2 or more (as you have 10.9)

          So 10.9 & 10.9.1 WILL HAVE TO REPATCH no matter what, Even if you download via AppStore.
          Once you have at least 10.9.2 or 10.9.3 or 10.9.4, then no re-patch will be necessary.

          Or if you like anyone with 10.9.2 will NOT have to re-patch to go to 10.9.3 or 10.9.4 with download via AppStore.

          Of course if you download a combo update .dmg, then re-patch will be necessary.

    Just to say thank you for breathing new life into my aging mac pro 1, 1.

    I used SFOTT yesterday to install mavericks without any trouble whatever. It just worked like magic!

    I now have dual boot to lion or mavericks on a 2006 machine.

    Next for me, clovertown processors!

    I have an issue with the installer, I had created a Mavericks 10.9.3 installer USB with the 64 to 32 script, I am on Mac Pro 2,1 running OS X 10.7.5, but I can not boot from the USB drive and when I try to install I get an error message: “Could not find installation information for this machine”. Any advise please?. Thanks for the responses.

      Hello Javier,

      Have you runned the auto mode ?
      Did you go to settings and validate them ?

    J’ai installé le tout et ça fonctionne très bien, merci.

    J’ai seulement un doute par rapport à ma carte graphique et à ma carte SATA.

    -Mon ATI Radeon HD 5770 semble manquer un des deux pilotes selon les informations du système. Celui du ATY, VervetParent. Est-ce normal que le menu du Finder se trouve en haut des mes DEUX écrans?

    -Ma carte SATA semble aussi manquer un des deux pilotes, celle du IDE Controller.
    Voici ma carte ainsi que le boitier (enclosure):

    Merci pour tout


    • oem oem says:

      Salut André,

      Content que tu ais pu faire l’installation avec le script.

      Hélàs pour tout ce qui est Drivers & Co, je ne peux aider. Too much configs.
      De plus je n’ai plus accès pour le moment au MacPro1,1 qui me servait de test.

      Tu trouveras beaucoup plus d’infos sur MacRumors et consorts pour tout ce qui touche aux pilotes.

      N.B. : pour le menu sur les deux écrans oui c’est normal (et bienvenue) cela t’évite d’avoir à parcourir tout l’écran. tu cliques sur le menu qui est le plus proche pour toi et il sera celui qui est actif.

    Gracias por el fantástico trabajo.He instalado mavericks 1.9.4 perfectamente pero el mission control en las esquinas no funcionan correctamente y si por teclado. Alguna idea?
    Y he oído algo de poner tarjetas gráficas de pc cuales son si hay que hacer algo especial.
    Tengo un mac pro 2.1 con la ati radeon HD 5770 de 1024 mb y 12 gb de ram.
    Gracias por todo.
    Y siento escribir en español ya que en ingles no tengo tanta soltura, aunque he visto que también esta en frances y si podría escribir en frances.
    Lo dicho mil gracias.

      Hola Patrick,

      No puedo ayudar for “drivers issues”.
      perdona mi español, hace mucho tiempo para mi…

      Si puedes escribir (leer) en frances… va sur ou tu trouveras des infos sur les Upgrade de cartes vidéos compatibles.

      Normalemente tu tarjeta grafica esta bien.

  7. Avatar Petr says:

    Hi, can I ask if is SFOTT compatible with latest version of Mavericks install app downloaded from App Store? I spend several hours triing to create Mavericks boot flash for Mac Pro 1.1 (upgraded to 2.1) with same result: it hangs when flashdisk is selected upon boot (holding ALT button). Tried it several times with different flash disc and internal 10 GB partition, always same result – hangs after clicking to SFOTT disk selection. No error, but sometimes after several minutes it boots back to Lion. Tried all manual steps, there is no single error message in the process.

    • oem oem says:

      Hello Petr,

      Well I’m begining to think that MacPro1,1 upgraded to MacPro2,1 can have issues….

      One suggestion would be to repatch the key before using it for the MacPro1,1 too.
      Maybe at some point it could help.

      Now to answer your first question, I don’t remember if in my numerous tries I did create a Key from the latest 10.9.4 downloaded from the App Store…
      I’ll give it a try if I can, but will only be able to test on the Mini for now;

      Q : have you tried with a FW drive ?
      Q : have you tried front AND back USB ports ?
      Q : Have you tried PATA/IDE ? (I did most of my installs on the MP1,1 with an old IDE disc below the Optical drive with success – and also have tried the same disc in FW with an external enclosure)

  8. Avatar Jeff Waldron says:

    I’ve have a 2006 Mac Pro working great for some months now on 10.9 thanks to SFOTT, but I have one issue that I could not see any comments around… my email search returns nothing… so I assume the indexing is broken… Spotlight works on the computer though… I tried to “Rebuild” the mail folders, it goes through the process, but does not change behavior. On this machine I have a separate drive w/ 10.7 installed.

  9. Avatar Jeff Waldron says:

    my bad, ignore that question… i had my Mav 10.9 drive in the privacy section in Spotlight

  10. Avatar Anthony says:

    I bought a Mac Pro 2.1 which had Maverick 10.9.1 installed. It did not come with the Maverick reinstaller in the application folder or elsewhere on the computer. I have no idea what software was used to make the conversion. I was told not to install 10.9.2 or it would freeze. I do not know how to get the 10.9.1 installer to make a USB startup drive as per instructions here. The AppStore will not let me in to get it. Can I buy a Maverick 10.9.4 startup USB drive and then install SFOTT? At least I would know what conversion system I am using.

    • oem oem says:

      Hello Anthony,

      Can you be more explicit on the “AppStore will not let you in” ?
      Maybe a Cameleon install – which I don’t know a single stuff on.

      1st) don’t buy anything but a new (virgin – empty) USB Stick.

      2) if you can’t get Mavericks from Appstore :
      2.1 to get it, try a friend or MDE – Maverick Download Enabler – from rastafabi on Macrumors.
      2.2 buy a NEW HARD DRIVE to test on, and remove you current system HDD and any other, as if it was mad by alternate chameleon instll you don’t want to mess things up and crash your actual setup.

      2.2.1 nuance : use you actual setup to create a SFOTT USB stick, then remove all drive but the TEST Hard Drive.
      If you succeed, then you’ll be (should be) able to go to AppStore

      Hope I’m clear, come back if I’m not ;)

      my best

  11. Avatar Patrick says:

    SFOTT saved me a lot of time in after both my backup and main HD crashed during a backup (doh!) last night. Being completely devastated by this event, I really wasn’t into going the traditional route in recreating a proper installation USB stick at 2am in the morning. Luckily I found SFOTT and in no time I had my MacPro1,1 back on 10.9.5. A real time saver and god sent gift.

    Thanks for your work, thanks for keeping this free to the community!
    Looking much forward on your work for Yosemite …
    Best, Pat

      Hello Stoney,

      This is quite strange indeed. What I understand here is that the boot.efi files are not present.
      Where did you get the installer ? Did you downloaded it from the AppStore.

  15. Avatar james hughes says:

    just want to say how awesome it is that I can use my Mac Pro V1,1 again. thanks you so much for this installer.
    Mavericks is rockin on it, and I had a ASUS HD 7890 lying around that’s working nicely.
    I didn’t realise that it would also let me use PC versions of Graphics cards. Is this all part of the features of the patch?
    Is there a list of graphics cards that will work anywhere?

    nice work guys.

    • oem oem says:

      Hello James,

      Great it worked. For the graphic cards, it is since Mountain Lion that PC cards can be use.
      No it is not because of me, way more beyond my skills. I’m not Netkas nor Tiamo :)

      Note : the only issue with PC cards is that you surely will have a black screen at boot until drivers are loaded. Always keep the original graphic card if possible so you can chooose disc at boot and debug in case of trouble.
      For a list of graphics cards, xlr8yyourmac and macrumors are a good starting point.

  19. Avatar Masahiro says:

    I have succeeded installing Mavericks 10.9 and upgrade to 10.9.5 successfully thanks to your software, however, every time when I use Apple Emigration Assistant to transfer my data from 10.7 drive, it fails to restart back to 10.9.5. (The computer starts with Vermose mode and hangs up.)
    Do you have any suggestions what to do? I am curious what are other people commentating about the file transfer after finishing the installation?
    I would appreciate if you could let me know.

    • oem oem says:

      Hello Mashiro,

      I’ve not tried Migration Assistant, but other did. I you have such behaviours,
      I’d suggest you do it step by step…. like
      Users first, I would not try settings, I’d hope for Apps to be transferred.

      • Avatar Masahiro says:

        Hi Oem,

        Thank you for getting back to me.
        If the boot.efi is rewritten by using Migration Assistant, is it possible to patch and reinstall the boot.efi by using SFOTT?

        Someone also said that Applications is OK by using Migration Assistant but not Personal or Networking Set up.


        • oem oem says:

          Hello Masahiro,

          yes there is function in the latest Sfott to repatch the system.
          either you install the SFOTT (via the installer) on the key to be sure everything needed is there, or you use target mode if you have another bootable system. Then using re-pach System from the script will replace the boot.efi once again.

          For migration Assistant I’ve not tested it actually… obviously Computer Settings and others Networking do not work. (I’m surprised but it seems to be)

            Hi oem,

            I wanted to try installing Yosemite by using your latest SFOTT installer (ver.1.4.4).

            I launched this SFOTT and only found 10.9 and Mavericks pre-written in your Terminal text. No 10.10 or Yosemite are written in it. Can I still use this version or you have a newer version for Yosemite?


          • oem oem says:

            Hello Masahiro,

            There is a “beta” version of Sfott for Yosemite. I have to finish the code and include it in the Official release.
            for now, please go there : AND READ ;).

            Week-end was busy so I do not code much, but I’ll do my best to release it ASAP officially.

  20. Avatar Masahiro says:


    I used your “beta” version of Sfott for Yosemite” and successfully installed a retail version of Yosemite.
    All I did was to rename ‘Install OS X’ to ‘Install OS X Yosemite’.
    I haven’t had any problem so far.
