Introduction

Keep your aging Mac from going obsolete by installing a patched version of macOS Ventura.

If you cannot Download MacOS Ventura on your Mac, download it after you installed OpenCore, as we will explain in step 11.

    • If you're currently running macOS Mojave, click this link to find the Mojave installer in the App Store. For Catalina, click here.

    • For all earlier versions of macOS, launch the App Store on your Mac, and search for the macOS version you want (this option is only available when running macOS High Sierra and lower)

    • Click Get or Download

    • If you have previously downloaded this version of macOS using the current Apple ID account, you might find it in the "Purchased"tab.

    • The installer is not directly available to Windows users. If you're using Windows, in order to get access to the installer, you'll need to borrow a macOS machine, go to a Apple Retail Store and download it there, or use a Hackintosh.

    I have previously downloaded this file, but it does not show up on my purchased list. Also tried Apple Support downloads, but they only have “Update” versions to download.

    Peter Simons -

    If, you’re on macOS Majove, it’s impossible to download previous versions of Mac systems. Excepted, macOS High Sierra but, I don’t know for how long.

    Anthony Fassler -

    If you have issues logging into the (App Store -> purchased) due to 2FA, get the code sent to your device and append it to your Apple ID password to log in

    Joe Verba -

    You can download older versions of the OSX. Here are the download-links (unfortunately an article in german, but you can find the download-links below):

    https://www.macwelt.de/a/high-sierra-sie...

    Gerrit -

    If you already have Mojave and just want to download the installer, you might not able to until you disable auto update.

    Just head to the Mojave page:

    https://apps.apple.com/ph/app/macos-moja...

    Then click the download button.

    Software Update will come up, click Advanced and uncheck the auto update.

    You will be able to download now.

    Hélas , en effet : j’ai été prise de vitesse car je pensais devoir acheter un MAC neuf , et quand j’ai vu les performances à prix égal à celui payé en 2013 , j’ai dit NON !

    Comment continuer de me servir de mon MAC BBOK PRO ?

    Votre site répond à toutes nos question , même l’assistance en ligne de APPLE est incompétente !

    Merci

    I’m trying to make a bootable usb for El Capitan for a SSD - my current working mac is High Sierra - is this doable? I keep getting errors because El Capitan is too old to run on my working mac.

    Hi Claire did you get any response about this enquiry?

    • After the downloading process is complete, close the App Store. The installation window should appear afterwards.

    • [*red]Click the "Install macOS (whatever version you have downloaded)" menu at the top left of the screen, and select "Quit Install macOS (whatever version you have) ."

    Il est également possible de passer par le soft “DiskMaker” pour faire cette clé.

    Il est gratuit, le prendre en fonction de la version de l’OS.

    Frédéric LEGER -

    Merci Frédéric !

    La solution à ce problème peut être très simple, comme vous l'avez écrit.

    Hermes Serrano -

    I downloaded High Sierra on a MacBook Pro already running 10.13.6 and then quit the App Store. No installation window appeared. What does ‘close the App Store’ mean?

Karl Heinz Darwin schildert über seinen Bruder Johannes Darwin seine dümmliche Idee der Natürlichen Zuchtwahl. Es gelang ihm der wissenschaftliche Beweis, das alles Negative wie Wirtschaftskrisen aufgrund der natürlichen Habgier von Managern, Bürgerkriege und Völkermorde sowie Rassendiskriminierungen biologisch auf Darwin zurückzuführen sind. Sie haben alle denselben Vorfahren, nämlich Charles Darwin.

    You actually have to run the InstallMacOSX.dmg, then the InstallMacOSX.pkg

    Malheureusement aujourd’hui il ne sert plus à rien de créer une clé bootable pour MacOS X 10.11 El Capitan, les serveurs Apple refusant de valider les paquets à l’installation…=> on se retrouve avec une brique inerte en guise de Mac !

    • Insert your USB drive into your Mac's USB port.

    • Open Finder to find your USB or if your Finder preferences have been set, you can find it on the Desktop.

    • Your USB drive will be completely erased in the following steps. Make any backups of your data beforehand.

    • Launch Terminal.

    • You can either use Spotlight or navigate to "Utilities" inside of Applications within Finder and double click Terminal.

    • In Terminal, type one of the following commands, depending on your version of macOS. (The name of the version of macOS, is the one you want to install on the key and downloaded.)

    • Instead of "/Volumes/MyVolume", type the name of your USB drive. Type everything else exactly as you see it (or better yet, copy and paste it from here).

    • For El Capitan : sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app

    • For Yosemite : sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ Yosemite.app

    • For Mavericks : sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ Mavericks.app

    • For Sierra : sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ Sierra.app

    • Other versions, see the next step.

    Are these referring to the OS you're making the bootable device for or the one you're making it from?

    Joshua Montzka -

    Looks like it is probably for the OS that you are installing.

    Joshua Montzka -

    Yes it's for the OS that you want installing on USB key.

    Anthony Fassler -

    Add ““ at start “/Applications/Install OS X El Capitan.app” and at end

    Bitsn Bytes -

    For High Sierra: sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ macOS\ High\ Sierra.app

    Александр -

    definitely copy/paste there are spaces in the command that aren’t obvious in what you see in the instructions. Also, in the replacement of Volumes/MyVolume - only replace the word MyVolume with the name of your USB - this wasn’t clear from the instructions.

    If you need to change the name MyVolume you should copy/paste in pieces as you can’t go back and type over what you input in Terminal

    lch63 -

    Great point. That saved me! Thanks!

    Magnus Dalen -

    what is the application path if I had not downloaded it from the Mac App Store because its not available? I downloaded it from an download-link, but the path is not showed. need help

    Zoran Borschak -

    The best way to make it, is to delete the path after sudo until —volume and to go in your installer with right click, select contents, go in folder Ressources and drag and drop createinstallmedia on your terminal after sudo. after that, check the space after sudo and before —volume.

    Anthony Fassler -

    Easiest way to carry this out is to rename your USB volume “MyVolume” before you do anything else. This lets you copy and pate the Terminal commands without worrying about getting every last keysrtoke and space correct.

    You can rename it to whatever you like afterwards.

    James Demers -

    Worth noting that this generates an installer volume. It won’t boot the Mac with a fully functional OS.

    James Demers -

    James Demers last comment on this whole process “won’t boot the Mac with a fully functional OS” is a show stopper if true? The title of this page completely leads one to believe the solution will be created after going through this process. Aside from that when running … sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app - (yes I named my USB ‘MyVolume’) After being prompted for this users password and entering it, the terminal is presenting "User is not in the sudoers file. This incident will be reported’

    Kevin Russell -

    “"no such file or directory”” this is my response message on this step

    Constantin-Romica GRIGORIU -

    bonjour j’ai besoin d’aide… COMMAND NOT FOUND. J’ai téléchargé OS X ELCAPITAN mais il se nomme donc : InstallMacOSX.dmg comment je fais ? Quelle est la bonne ligne à rentrer dans le terminal ? Je sèche, j’en ai besoin pour cet apres midi. Le InstallMacOSX.dmg je l’ai mis ds mon dossier APPLICATIONS car il etait ds téléhargements

    guigui.laetitia -

    Renaming my USB drive MyVolume worked perfectly.

    The mistake I made was dragging instead of Copy and Paste. Once I did copy and paste it worked.

    James Mulligan -

    I keep getting the error : /Volumes/MyVolume is not a valid volume mount point.

    Andrew -

    Apparently there’s a problem with the Sierra installer downloaded from Apple recently, making you end up with a Terminal response “MyVolume is not a valid volume mount point.”

    After searching through the Internet I found the solution here https://www.reddit.com/r/macsysadmin/com...

    Something’s wrong with Apple’s new installer, so you need to fix it first, with the following command:

    sudo plutil -replace CFBundleShortVersionString -string "12.6.03" /Applications/Install\ macOS\ Sierra.app/Contents/Info.plist

    Then follow the instructions in step 5.

    Nicolas Bertin -

    Bonjour, s’il vous plaît par quoi remplace t-on le chemin du fichier qui ce trouve après "applicationpath"?

    ERIC N'SAH -

    Il n’y a rien a changer après "applicationpath"

    Anthony Fassler -

    I downloaded El Capitan directly from the Web & not the AppStore. How can I get the path to work properly?

    Jeff Jotz -

    Hello,

    On the Terminal, write “sudo” and after drag and drop your El Captain file.

    Paste after “.app” this “/Contents/Resources/createinstallmedia --volume“

    Put a space after volume en drag and drop your USB key.

    Put a space again and paste it “--applicationpath”.

    Put a space again and drag and drop your El Captain file.

    Anthony Fassler -

    Thank You very much Jeff, you solved my problem !!!

    Sabine Kenouch -

    Make sure that Finder or any other app doesn’t access the USB drive, otherwise the deletion/formatting may fail

    Beate Tatzel -

    try erase and partition the usb before sudo command in terminal

    Hello. Rename USB key to MyVolume but still have the message: sudo: /Applications/Install macOS Sierra.app/Contents/Resources/createinstallmedia: command not found

    Hi I have a mid MacBook Pro 13’ mid 2010 with Mac OS High Sierra 10.13 on it trying to create a bootable usb done all the steps but when it comes to terminal it advise Sudo : command not found… please help

    Ridzal Yusri -

    Remplacer le chemin "/Volumes/MyVolume" par celui de votre clé USB, Pour ce faire, supprimez le chemin actuel puis faites un glisser-déposer.

    Comment connaître le “chemin de ma clé USB” ? Qu’appelle-t-on le “chemin actuel”? Merci d’avance.

    Malzieu -

    Le plus simple c’est d’effacer /Volumes/MyVolume et de faire un glisser déposer

    Anthony Fassler -

    Ich bekomme die Fehlermeldung:

    No auch file or directory

    Reza Eskandari -

    First you should make sure you replaced "MyVolume" with the actual name of your device, if it doesn't appear on your desktop when you insert the drive you can easily get it by opening Finder and checking under "devices" in the sidebar. As Ich63 pointed out you will need to copy/paste in pieces as the terminal will not allow you edit the text that much. Alternatively, just rename it "MyVolume" as suggested by @jpdemers and copy/paste the command as is.

    Simone -

    I keep getting a command not found in terminal even though i copied and pasted exactly as written after replacing the volume/myvolume

    Brian O'Keefe -

    I'm running a 2016 MBP running Monterey and looking to create an installer for el capitan so I can resurrect my old 2007 Imac 24 that I have Ubuntu running on. Where can I get an installer for El Cap. Every one I get has the dmg but won't go any further.

    Ralph Fasano -

    You can download the El Capitan image here : https://mega.nz/file/xw8yEAoJ#r0_KpSdrpP...

    Anthony Fassler -

    I have a M1 mac and cant install intel macOS, I dont know how to install El captain or Yosemite any way else. I need it to install some sort of macOS on a 2008 iMac. I saw the link someone posted above but when I tried doing the command it said "the developer cannot be verified".

    Jeremy T -

    Hello,
    Have you tried to open the image by right click and open, before launch the command in the Terminal ?

    Anthony Fassler -

    I just tried that and now it says that it is too old to be opened.

    Jeremy T -

    Ok now, put the El Capitan image in the Applications folder and try to create your USB stick by the Terminal.

    Devern -

    For what OS ? I remind that, it’s for the system that you want install on your USB Stick not, the one that you’ve on your Mac.

    Anthony Fassler -

    Did not work I get a message that ot had to run on root

    Luis Suarez -

    For versions of Mojave 10.14 and higher, the proper command is:

    sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume

    James Demers -

    I want install High Sierra on usb. Get this error

    “sudo: /Applications/Install macOS High Sierra.app/Contents/Resources/createinstallmedia: command not found”

    Richard Littell -

    I get a “/Applications/Install macOS High Sierra.app does not appear to be a valid OS installer application.” error. What now?

    tsa -

    Me too! I cant install it on USB. I tried everything

    Jan -

    für die mojave version führt folgender befehl zu erfolg:

    sudo /Applications/Install\ macOS\ Mojave.app/Contents/Resources/createinstallmedia --volume /Volumes/stick

    das usb medium in stick umbenennen oder den namen im befehl editieren zb in notizen

    Christian Razborsek -

    It keeps saying that my usb stick is not a valid volume mount point

    Lars K -

    The terminal command posted here to create a bootable drive installing High Sierra is not valid! Not a valid mount point.

    randy3833 -

    Instead of “MyVolume”, input the name of your USB Drive. Need to replace only the Highlighted part of the command

    Andy -

    Thanks Andy! Sorry, I just noticed your helpful reply. I somehow figured this out on my own.

    randy3833 -

    I’m trying to create a Catalina boot utility on my macbook pro for an IMac that was given to me. The IMac has the flashing screen of file folder with question mark inside of it. I just upgraded my Macbook to Catalina from Sierra last night in order to create this boot disk on my “Untitled” drive. I’ve typed the following:

    sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

    And it gives me a command not found error. What am I doing wrong? I have typed my password and it still says not found.

    sudo: /Applications/Install macOS Catalina.app/Contents/Resources/createinstallmedia: command not found

    Damon Grier -

    What macOS do you have on your MacBook Pro ? If your Mac is using macOS Sierra or earlier, add

    --applicationpath /Applications/Install\ macOS\ Catalina.app

    So,

    sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ macOS\ Catalina.app

    Or if you have macOS High Sierra or higher,

    sudo /Applications/Install\ macOS\ Catalina.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled

    Of course, you must have the Install macOS Catalina on your Applications Folder.

    Anthony Fassler -

    I was getting this error:

    createinstallmedia: unrecognized option `--volume /Volumes/HS --applicationpath'

    THIS WORKED:

    I RENAMED ‘Install macOS High Sierra.app’ TO ‘IHS.app’

    I NAMED MY USB ‘HS’

    sudo /Applications/IHS.app/Contents/Resources/createinstallmedia --volume /Volumes/HS --applicationpath /Applications/IHS.app

    Ready to start.

    To continue we need to erase the volume at /Volumes/HS.

    If you wish to continue type (Y) then press return: Y

    Erasing Disk: 0%... 10%... 20%... 30%...100%...

    Copying installer files to disk...

    Copy complete.

    Making disk bootable...

    Copying boot files...

    Copy complete.

    Done.

    I hope this helps someone

    Paul Anderson -

    the path for the El Capitan Version seems to be wrong? I used the path from the apple site “sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app” and that one is working!

    ptherbert18 -

    I keep getting a command not found in terminal after copying an pasting :

    sudo: /Applications/Install macOS Sierra.app/Contents/Resources/createinstallmedia: command not found

    here is what i pasted in: sudo /Applications/Install\ macOS\ Sierra.app/Contents/Resources/createinstallmedia --volume /seirraInstall --applicationpath /Applications/Install\ macOS\ Sierra.app

    is something missing?

    Brian O'Keefe -

    I found this confusing but discovered that only "MyVolume" needs to be changed to the USB name - not all of the bold text. So, to install Big Sur (with the USB called BigSur) one would make the following command: sudo /Applications/Install\ macOS\ Big\ Sur.app/Contents/Resources/createinstallmedia --volume /Volumes/BigSur Hope this helps!

    • After correctly entering the command with the name of your USB drive, press the [return] key.

    • Enter the macOS administrator password.

    • Your password will not be displayed.

    • Press [return].

    • Check the name and path of your USB key. If it looks correct, press the [Y] key, then press [return].

    • The bootable drive creation will begin. Please wait until the process completes.

    I did as suggested and named my USB drive “MyVolume” and copied & pasted command line for El Capitan.

    Got these messages about the USB drive erasure failing:

    “Ready to start.

    “To continue we need to erase the disk at /Volumes/MyVolume.

    “If you wish to continue type (Y) then press return: y

    “Failed to start erase of disk due to error (-9999, 0).

    “A error occurred erasing the disk.

    Any suggestions?

    Happened with two different USB drives; one was brand new.

    Should add that I’m doing this on a 2010 MacBook Air running 10.6.8

    Richard Harley -

    I think you have to change the format first of your USB. I did it with a brand new USB and had not trouble. To do so, insert your USB and open Disk Utility and go to Erase in the upper menu. Choose to erase your USB and change the format to APFS or MacOSPlus (with register).

    Luxedrina Trementina -

    I’ve done all of the steps and unfortunately, Terminal keeps coming back with this response:

    “APFS disks may not be used as bootable install media.”

    Would you happen to know a workaround? I’d like to be able to use my external SSD usb drive as a boot drive. Many thanks.

    Glenn Howard -

    Make sure that Finder or any other app doesn’t access the USB drive, otherwise the deletion/formatting may fail

    • When Terminal indicates the process is "Done," the creation of your bootable drive has succeeded.

    • To boot off the USB, first make sure the Mac is off and then press and hold the [option] key when you hear the chime/turn it on .

    Really great guide. Nicely laid out and easy to understand. Nice

    Alec Chandler -

    Overall iFixit guides are great. This one is just good. The instructions are clear and easy to follow. However they involve typing or cutting and pasting a lot of text. This is cumbersome and highly prone to typos, etc. there are several other sites where you can find instructions that talk about free apps that walk you through creating a bootable usb drive. Another one of them has a nifty trick of simply dragging the icon for the usb drive to the terminal window. So while these instructions are clear and work, there are les error prone ways to achieve the same result.

    Stephen -

    Pretty good guide, especially for a community member. Thanks

    Sam -

    I’d add that step 7 can take a while before you see any progress. I’d estimate five minutes (on a 2014 MBP writing to a thumb drive) before the 0% changes to 10%.

    gyorke -

    I’ve created the bootable USB drive with the El Capitan installer downloaded from the app store to my MacBook and successfully booted my 3,1 mac mini with it, but when I try to run the OS X installer I get a message to the effect that it ‘can’t be verified and may have been corrupted or tampered with’ and the process won’t continue. I’ve re-downloaded and tried twice, same thing….. Anyone have any ideas how to proceed?

    echoplex -

    go to http://osxdaily.com/2015/01/19/fix-os-x-...

    Anthony Fassler -

    I really appreciate this guide, as well as the person who took the time to put it together. Personally, the LAST thing I want is to add yet another app to a system when there is a way to do it myself without installing anything. But I am a hands-on kind of gal to start with, & I was a tech dept employee for several years in the school system (right around the time the schools began transitioning from Mac to PC :( )

    Thank you.

    Everything on ifixit.com is great! I following everything successfully up unitl the part that reads: “To boot off the USB, first make sure the Mac is off and then press and hold the [option] key when you hear the chime/turn it on .” I ejected the bootable drive, as I was creating the bootable drive on my Mac desktop, and the MacBook Pro is what I am doing the hard drive replacement and install on. I did not read the very last instruction until I had already ejected it. Once I powered on my MacBook Pro and inserted the bootable drive, the computer came on and showed me a screen for typing in my password, only my password doesn’t seem to be the right one. HELP!!!

    Jeffrey Fox -

    Have you tried with Apple ID and session password ? Otherwise, you can reset your session password with the recovery mode. On start your Mac press the touches CMD + R, when the recovery mode screen appeared, click on Utilities in the menu bar followed by Terminal. On the Terminal enter the following command : resetpassword and press Return

    Anthony Fassler -

    Hi for step 6 it is showing up as createinstallmedia: command not found after hitting enter for my High Sierra OS. let me know what may be some of the reasons why it is not letting me go to the next step is to click “Y” ..

    Remi Oguni -

    Thanks,installed on an external ssd drive using BigSur,super fast now.

    Steve Odonoghue -

    worked perfect, thank you!! Better than Apple’s own support

    Kamil Isik -

    after booting in the new drive, and chose Instal Big Sur, the drive is apparently locked and cannot be written over.

    C Reese -

    All went well. The only difference I encountered was in the info at the top of Step 8: using Terminal with Big Sur 11.7.2, the end of the process did not read "Done" but "Install media now available at "/Volumes/Install mascOS Big Sur"." Ejected the flash drive, and installed it on another device without issue. Thanks!

    • If you cannot download the MacOS intaller of the version you want to install, you can do it using the OpenCore app after you install it. We will see how to do it after we installed OpenCore.

    EqRFgJ4LbYUlPufY

    • Go to this link and check the last release of OpenCore Legacy Patcher. At the time of writing, it was version 0.6.5.

    • Scroll down the page until you find the Assets section of the latest release. Open it and download the file named OpenCore-Patcher-GUI.app.zip.

    • After the download ends, open the zip file to extract the OpenCore-Patcher app and open it.

  11. TBAqqEOLxLrEI3aX

I've been running this on an old Mac Mini Late 2012 semi-successfully. However it seems some menus get blurry and some apps none of the art elements will load. Guessing it's things that try to call on Metal. Anyone seen or aware of a fix for these bugs?
