10.9.5 Update and SFOTT | All smooth but BEWARE (again)

10.9.5 Update runs smooth.

No need to repatch the System once done, like for the previous 10.9.3 / 10.9.4

I’ve just downloaded and installed the 10.9.5 Update on my Guinea MacMini2,1 with no hassle.
Note I do not have access to the Macpro1,1 for now.

This Update still installs in two steps :

  • 1°) (download from Mac App Store, then) installs stuff BEFORE rebooting
  • 2°) continues the install on a second step after reboot.

Like 10.9.3 / 10.9.4 , it goes fine and the boot.efi is not replaced like it had been in the 10.9.2 previous update. Thanks Apple ;)
IF YOU ALLREADY installed either one combo (10.9.3 / 10.9.4 ) or the 10.9.2 and patched the boot.efi again, then it should run fine.

Note: I’ve tested from 10.9.4 to 10.9.5.


If you download the Update via AppStore: working out of the box.

No Need to repatch this time:

If you download the Combo from Apple website.

I’ve not tested this, but as said above, if you have not 10.9.2, then you’ll surelly have to rematch “again” once update is done. please follow the steps from the 10.9.2 procedure here

La mise à jour 10.9.5 se déroule bien.

A nouveau pas besoin de Re-patcher le Système cette fois-ci.

Je viens de télécharger et installer la mise à jour sur mon MacMini2,1 cobaye sans accroc.

Cette MàJ se fait toujours en deux étapes :

-1°) (téléchargement depuis le Mac App Store, puis) installation de l’étape 1 avant de redémarrer.
-2°) Redémarrage et retour sur le système.

Comme pour les MàJ 10.9.3 / 10.9.4, tout se déroule bien et le boot.efi n’est pas remplacé comme ce fut le cas avec la 10.9.2 précédente. Merci Apple :)
Attention, si vous n’avez jamais installé la 10.9.2 (soit directement soit via la combo 10.9.3 / 10.9.4 ) alors cette 10.9.5 sera une combo et vous devrez quasi certainement suivre la procédure pour le “repatch” de la 10.9.2 en suivant les instructions ici

note: J’ai fait la MàJ depuis 10.9.4 vers 10.9.5.

! Attention !

Si la MàJ est téléchargée via l’App Store, elle se déroule sans problème, depuis une 10.9.2 ou 10.9.3 ou 10.9.4

Pas besoin de repatcher cette fois-ci, non plus.

Si vous téléchargez la Màj depuis le site Apple,

Faites attention, si vous n’avez pas DEJA installé la 10.9.2 alors vous devrez certainement patcher en suivant la procédure pour la MàJ 10.9.2
de la même façon si vous télélchargez la MàJ “Combo” vous devrez à coup sur repatcher encore. Evitez les MàJ Combo sauf gros problème si vous avez deja fait 10.9.2 et/ou 10.9.3 et/ou 10.9.4

    Just wanted to let you know I successfully updated my MacPro 1,1 to 10.9.5 via AppStore without any problems.

    Thanks for all your great work.

    Best regards,

    Just updated my 10.9.4 MacPro 2,1 to 10.9.5 from Apple updater … also no problems.

    FYI … I just used SFOTT last week to update my MacPro to Mavericks. The current Mavericks installer from App Store installs 10.9.4 so only single patch is needed.

    ALSO … just for new folks wondering ….

    The 10.9.4 Mavericks Full Installer was able to UPDATE my Mac OS 10.7 boot disk … no need to do a fresh install of Mavericks. So all my Applicatons, settings, etc … were all still there after upgrading from OS 10.7 to OS 10.9. I was under the impression that a clean install was required but that was not correct.

    • oem oem says:

      Hello Dan,
      thanks to report.

      Well it’s good to know for sure about upgrading directly from a Lion System. This is a confirmation.

      Actually, even if I may not have been clear about this, I usually prefer to tell people to FIRST try on a Fresh Disc / Fresh install, and keep the running Setup in place at hand as a debugger/backup Setup.

      Then of course, Once it is sure that Mavericks runs smooth, try it on an existing system can ease things up.

      IN ANY CASE, for the readers I STRONGLY SUGGEST to always keep a CLONE (image and/or Disc) Of the current Setup (10.6.8 10.7.x) to prevent any trouble in case of… whatever.

      THe perfect exemple is the 10.9.2+ Update, if you had a running old 10.6 – 10.7 that was easy to repatch, in the other case you only have a Mavericks – Tiamo’s boot.efi, well you had to be a good “geek” and/or use the latest SFOTT version and unpdate the SFOTT key before….

      SO short answer : yes you can upgrade from lower to Mavericks but be SURE to always have a bootable running System at hand if you do so.
      as you may lost DATAS in case of trouble, as we have hacking, cheating tricking here :)

      Glad you made it out with no trouble BTW. !

      • Avatar Blackshapes says:

        I can confirm also that the 10.9.5 update goes buttery smooth over 10.7.
        I used a 10.9.2 installer from my old MBP, and she worked first time.
        Installed to an old 250GB HDD first to be sure, then dropped it straight over my SSD the second time. Worked a treat. Imported everything, apps presets and all. Piece of cake.
        On my MP1,1 it added a massive three seconds to the boot time. Yep. Three whole seconds. For a total of 20 secs from the chime to the desktop. Had a bit of snafu with the wifi at the start, trashed the bluetooth preferences and its like a supported system.
        Magnificent work oem and tiamo! Brava! You made my baby new again!

      hi dan. I have a macbook 2,1 and upgraded to mavericks but now I do not have any sound and video memory i only 6mb. I also canot connect my hdmi screen anymore coz it doesn’t respond when i connect it anymore…..Help please!!!!

      • oem oem says:

        Hello Tate,

        I’m sorry to tell you that, but getting Mavericks installed is one thing (I try to ease with the Sfott Key) getting a working computer is another thing.
        Please read How-to and reported installed pages.
        It is known that video is poor on some setup. My Macmini2,1 has poor video and has no wifi.

        Tiamo’s boot.efi worth it mainly for MacPro1,1, and MacPro2,1 and XServes.
        I can’t help you much more than helping getting a bootable installer USB stick with Tiamo’s boot.efi

        I am pleased to hear that!! I am happy to donate and whilst I am sure you are doing this for pleasure, what about setting up a charity link or something so those that want to, can?

          Hello David,

          you’re right on everything.
          I did plan to do a link if I reached 5K … ;)
          I finally think I’m going to do it so I can be sure I can keep this website up, and maybe buy a MacPro1,1 so I can test at home as I don’t have a macPro1,1 at hand since I changed job lately.
          Thanks again for your proposal;;;

    Mise à jours réussi en 10.9.5 via l’Appstore sur mon MacPro 2006 2.1!!!
    Mon MacPro pourra passer à Yosemite?!?!? Ça serait cool!



    • oem oem says:

      Bonjour SsYlleC,

      Bonne nouvelle pour 10.9.5 …
      Je dois me poser sur YOSEMITE rapidement maintenant,
      j’ai commencé mais un changement de vie et qqes vacances ont un peu ralenti la chose.

  6. 10.9.5 via App store worked perfectly on my old 1,1 MacPro.

  7. Avatar Mark says:

    The stand-alone OSXUpdCombo10.9.5.dmg update replaced Boot.efi on my macpro1,1 which required me to copy them back – so appears different to Apple store update. This was coming from 10.9.3.

    • oem oem says:

      Hello Mark,

      If I understand correctly : you updated via .dmg and had to repatch ?
      in a way, updating from 10.9.3 to 10.9.5 is a combo as you skip the 10.9.4. But I would have said that we would not have to repatch.
      Obvioulsy I would have been wrong. this is good to know and I’ll place it in the troubleshooting.
      Thanks for reporting this issue and tip.

      • Avatar Mark says:

        Yes, correct. I was was on 10.9.3 and used the 982.3 MB .dmg combo download that definitely required repatch – had to remove my gtx660 & put back in 8800GT and boot from back-up 10.9.3 to restore things.

        • oem oem says:

          ok thanks for the details !
          I have to include this on the troubleshooting page.


  8. Avatar Marcesh says:

    unfortunately my macpro2,1 wont boot anymore, after the update was installed via the appstore. all i get is a white screen with a flashing gray folder with a question mark. nothing from the web worked so far.
    normal system, just filevault2 was enabled

  9. Avatar Marcesh says:

    well this is a desaster so far. any help would be appreciated. i tried every hint there is in the web and the mac still wont come up. what i did now is remove the boot hd and connect it to my macbook to see if its damaged, which it isnt. i can access the hd just fine from another computer via a usb/sata adapter.

    to avoid problems with the encryption i used diskutil corestorage to decrypt the harddisk – which takes a while, and then i suppose i have to repatch the system.

    is it possible to create a new sfott key for a macpro2,1 from a valid mavericks installation on a macbook6,1? or is it possible to just repatch the connected macpro harddisk right from the macbook running mavericks?

    • oem oem says:

      Hello Marcesh,

      Well 1st for FileVault to work you must have a Recovery Partition. This is mandatory.
      Now to answer your last question :

      You can either create a new Key or repatch via the Macbook with the MacPro HD connected.
      Either way will work.

      – If you want to use the macbook and repatch the hard drive.
      Select the drive in settings, then select the “repatch again” (yeah should be “repatch”)

      – If you want to recreate a Key (you can on any Mac running 10.6.8 to 10.7 or 10.8.)

      You must know the correct Board-id and Model.
      The MacPro2,1 infos should be :

      In both cases you’ll HAVE TO enter Manually the Board-id and Model.
      but you’ll have to so you have to create a key or “patch it” with those infos, that you’ll have to enter manually in the settings.


      Hope it helps.

      Let me know

      • Avatar Marcesh says:

        found my old sfott key and used it to repatch according to your instructions – came up fine again. thank you!

        now i’m trying to move/clone my hdd to a ssd, that didn’t work well so far… no boot at all from the cloned drive…

        • oem oem says:

          Hello Marcesh,

          Glad you did it.
          Concerning cloning your HDD to a SDD I don’t see why you could not.

    Mac Pro 1,1 updated to 10.9.5 via app store. Works perfect.

    Thanks! Thanks! Thanks!

    Just to drop by and thank you for your awesome work :)

    I have updated my old Mac Pro 1,1 (2,1 firmware, Dual Xeon X5355 2.66Ghz, 16gig, GTX570) from 10.7.5 to 10.9.1 yesterday in around an hour and a half in total, upgrade worked like a charm on my first try without any problems at all :)

    I had to use my old 7300GT in PCIEX slot4 for the process (for boot screen), then switch to my main card GTX 570 after the installation to get into the newly upgraded OS.

    After the update to 10.9.1, when I was sure that everything works great, I made a fresh backup through my Time Machine and then downloaded the 10.9.5 combo update through App Store.

    After the system rebooted, I had to let it stand black for the first time and let it not boot (since the patched EFI was replaced by combo update).

    I have shut down my Mac and switched the display connection to the old 7300GT once again while inserting the SFOTT usb stick the the usb port. After the boot, I hold ALT and boot from SFOTT stick. Re-patched my current system in 2 minutes through your 10.9.2 procedure on the front page and voila!! After shut down I took out the old 7300GT and reconnected GTX 570 once again.

    Again, system booted flawlessly with 10.9.5 update!! Everything works great, no errors, nothing – with such simple process!

    Perfect work, I cannot thank you enough. You are the man! :)

    I hope that my comment helps some newcommers who are still on Lion and thinking about upgrading their old machines with the new OS Mavericks.

    Looking forward to Yosemite!

    Kindest regards,

    • oem oem says:

      Hello Tom

      Very glad you did so simply.

      Your comment is a real good, nice and effective synthesis ! I may use it on a short version of a How-to :)

      I’ll do my best for Yosemite

  12. Avatar Emil says:

    I can also confirm that updating from 10.9.3 to 10.9.5 via appstore required repatch, but everything works great. I have MacPro1,1 with 2 boot drives (second drive is Snow leopard) and two video cards so it was easy thanks to your instructions. One VC is ati radeon HD 2600 XT and second geforce 8800 GT for better performance but without boot screen. I was having one small problem with indexing. After transferring user from snow leopard to maverick, I can’t find anything on SL. Finally I discovered that disk with SL is added to privacy tab in spotlight system preferences. It seems like migration assistant added disk there. Before that I try your “enable spotlight” command and Onyx rebuild index but nothing helps.

    THANK YOU very much for your great work (and tiamo of course)
    Greetings from happy new Mac and me:)

    • oem oem says:

      Hi Emil,

      Ok so 10.9.3 to 10.9.5 requires repatch. It did not for me ?! Strange but noted.

      Concerning my Enable Spotlight command it is only fr the Mavericks System as there was a “bug” in some release that I corrected just after.
      The Command is here just in case. And it won’t help for others Disc but the System.

    Wanted to pass on my thanks to you for this wonderful site and it’s information. Jumped directly from Lion, 2007 Mac Mini 2,1 to Maverick 10.9.5 without any problems. Did my combo update from the AppStore this morning . No issues.

    • oem oem says:

      Hello Don Carlos,

      Great you too have a Mini2,1 working with Mavericks.
      Note that graphics will be poor and you won’t have wifi unless you use USB dongle o change the card for example.

  14. Avatar Francesco says:

    Hi guys,
    really hope someone can help me. I’ve managed to install Mavericks 2 months ago. Everything run smooth until yesterday, when I’ve updated Little Snitch. My Mac won’t boot anymore! I’m stucked with the grey Apple and the wheel spinning and then again it reboots and again and again.

    I’ve tried booting from teh SFOTT key and repatch the system with no luck. I’m on a Mac Pro 1,1 with Mavericks 10.9.5.

    How to reinstall the system with just the SFOTT key to boot from? Any idea?

    Thanks in advance

    • oem oem says:

      Hello Francesco,

      ok bad news.
      I could suggest one thing.

      boot from the key and before installing, choose the Menu -> disk utility.

      There create a second partition, so you’ll be able to install again. and eventually once done and booted from the newly installed System, ask to transfert Datas Users. I would not check Apps as Little Snitch will also be installed and mess again.

      If you don’t care about your Datas (as you have a Backup somewhere), simply erase the partition instead of creating a new one.

  15. Avatar NKT says:

    Has anyone ever installed Mavericks onto a Mac Pro 1,1 like this?

    1. Install Mavericks using target disc mode from another machine (in my case a macbook pro retina using firewire via lightning to firewire adapter)
    2. replace boot.efi while still in target disk mode

    That’s literally all I did, this was after several attempts to get other methods to work and they just wouldn’t.

    • oem oem says:

      Hi NKT,

      I think some did.
      You also simply use the script to “repacth” the System by choosing it settings.
      As simply changing boot.efi will not pacth needed plist.
      If it did work for you, then of course plist patching may not be as needed as I think.

    hello i need to know how to install the maverick on a mac pro 1.1
    the problem is i installa a new hard drive and i dont have operating sistems what u recomend me i want to run mavericks but how i start from cero and tnx for ur time i apreciate..!!!

    • oem oem says:

      Hi HadesAlec,

      you must have a running system at least 10.6.x to create the sfott key.
      and an Installer of course.
      If you have no running System you’ll have to find a friend to create the key.

    I followed the steps

    1.) I downloaded the Mavericks Install App fro the App Store. on 10/2/2014
    2.)Went through the setup
    3.)It burned the USB stick.
    4.)Rebooted with the stick in the usb port.
    5.)Chose OSx Base system.
    6.)It booted off of the usb stick but is said “A problem with intall.”
    Tried it multiple times
    I am on Mac Pro1,1 with a GTX8800 video card.

    Is the latest version of the Mavericks app a newer and imcompatible version? Or …..

    Please Help
    Thanks in advance

    • oem oem says:

      Hello Christian,

      Could you give the exact message ?
      and describe at what “step” it occurs ?
      boot time, during install, before install but after boot time???

      Some have used the 8800GT, I don’t know for the 8800GTX (not that good with graphics cards)

      Can you try to use an internal disc/and or partition ?

  18. Avatar JustMe says:

    My Mac Pro 1,1 which was 10.9.3 would only show a white screen with folder and Question mark. It killed the boot.efi. I had recently purchased a used MacPro and without knowing the tricks, I just used App Store and clicked update. Lesson learnt – never do this again on the main system.
    I will continue to wait until Yosemite is tested, then I will take a risk. But now I know this website and will use later.
    Thanks for all the hard work.

    first of all, thx a bunch for making all this work!! maverick has been running great, but i have the same problem as stated from some people above, after updating from 10.9.3 to 10.9.5 my mac wont reboot once the patch is installed. only a folder with a white question mark flashing.. (have tried like three times) any ideas on this? im on a 1,1 MacPro btw. its not a big deal to recover with the initial sfott stick, but would be great to be able to do future updates…
    thx again!

    • oem oem says:

      Hey JBC,

      ok so did you updated 10.9.2 or straith to 10.9.3 ?
      was from AppStore? or dmg ?

      Same questions for 10.9.5…

  20. Avatar Colin says:

    Can I update straight from 10.7 to 10.9.5 using the SFOTT key? Or do I need to use a previous version?

    Thanks for all your hard work!

    • oem oem says:

      Hello Colin,

      You normally can update to the latest version and create the key from any. The last version will save you hassle of Updates.
