Introduction

Create a bootable USB drive for macOS X El Capitan, Yosemite, Mavericks, Sierra, High Sierra, and Mojave.

(The process is also described on the Apple Support page https://support.apple.com/en-us/HT201372)

  1. 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'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.

    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.

    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.

    • 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.

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

    • Other versions including High Sierra and Mojave : see the next step.

    • If you did not download the file from the App Store, you must modify the file path after "applicationpath".

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

    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

    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 - Reply

    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.

    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.

    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?

    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 :( )

Hi, I made a USB bootable drive with el capitan on it. Everything worked fine. I replaced my old hdd with the guide from this site. My iMac is from 2007. But now when I try to boot my computer with the Usb drive while holding the option key I only get a grey screen with a cursor. Any ideas?

Matthias Caes - Reply

Hi,

You must press the Option / alt key immediately after pressing the start button (no need to wait for the startup sound) and normally you can select your usb key.

Anthony Fassler -

That's what I do though. With all the other key combinations I end up with a blinking folder icon with a question mark. i have tried the vpram reset as well so the problem isn't my keyboard. Could it be the usb itself? Or some other problem? If I did something wrong during the hdd replacement I figure I wouldn't have gotten this far, no?

Matthias Caes -

So, it probably comes from the usb key. When you had done it is that the key had the name of the operating system?

If that is not the case then there was a problem when creating.

Try any other usb port though, it's not already done.

If it still does not work, it will be necessary to put back your old hard disk to be able to start your Mac and follow the tutorial above (be careful to respit spaces and characters in step 5).

And check by pressing "alt" that this works well before putting your new hard drive.

Anthony Fassler -

I used a PC to make the usb drive. Downloaded the installer from the App Store and then transferred it to a pic where I extracted the .dmg file from the installer. I used a programme called transmac. I will see if it is possible to make the usb on another Mac. I know the whole process of making the usb drive on a pc was a detour but I didn't really have any other options... Thanks anyway for the help. I'll post back with progress.

Matthias Caes -

Sorry about forgetting to post back. I did the whole procedure on the PC again and it turns out I skipped a step so it all worked eventually. Thanks again for all the help.

Hi there,

Question for you. The step 5 am I copying the os code on the computer I currently have active or am I selecting the one that I am trying to download for the computer I just replaced the hard drive for? I’ve tried both and keep getting errors.

Here is an example:

Audras-Mac-mini:~ audracarpenter$ sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/BlkBackup --applicationpath /Applications/Install\ macOS\ High\ Sierra.app

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

Usage: createinstallmedia --volume <path to volume to convert>

Arguments

--volume, A path to a volume that can be unmounted and erased to create the install media.

--applicationpath, A path to copy of the OS installer application to create the bootable media from.

--nointeraction, Erase the disk pointed to by volume without prompting for confirmation.

Example: createinstallmedia --volume /Volumes/Untitled

Audras-Mac-mini:~ audracarpenter$

Thanks!

audrajcarpenter - Reply

Hello,

The step 5 is for OS that you install on USB key not for your actual OS.

Regards.

Anthony Fassler -

Hi Anthony, thanks for the response. Ok, so the example I posted above, I am trying to use for High Sierra, which is the one I downloaded from the app store. But I am getting arguments that it’s incorrect. Does anything stand out to you as to what I have posted above?

audrajcarpenter -

You’ve a problem with the path of your Volume.

Copy and paste the command line of tutorial because, there are spaces that are not very visible.

sudo@/Applications/Install\@macOS\@High\@Sierra.app/Contents/Resources/createinstallmedia@--volume@/Volumes/BlkBackup@--applicationpath@/Applications/Install\@macOS\@High\@Sierra.app

All symbol “@” are spaces.

Anthony Fassler -

Hi Anthony, thanks, but there is a space for each of them. I did just copy straight from the page. Any other thoughts what it could be?

audrajcarpenter -

So, format your USB key in format Fat32 with more simple name (UNTITLED) by disk utility.

Then copy and paste this command line :

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

Anthony Fassler -

Hi Anthony that worked! Thanks so much. QQ.. now that I have that drive, I’ve followed your instruction on installing on a new hard drive for a mac book pro 2010 but I’m getting a ‘This copy of the install mac0s high sierra application is damaged, and can’t be used to install macos.’

I’ve tried it twice, but still getting same issue. Do you have a how to around this that I can take a look at?

audrajcarpenter -

It’s an other problem, normally it's because of the time of your Mac that is not fair.

if, you have booted on the usb key. So, you have to set the time of your mac.

So, before click on install macOS, go to utilities/Terminal, enter this command line “date mmddHHMMyy” and change the lettre by the actual date.

mm=mouth, dd = day, HH=hour, MM=minute and yy = year (example = date 0824113518)

Anthony Fassler -

How long should the installer files take to load onto the USB? I’m currently copying El Capitan onto a 16gb USB, the file is only 6.something Gb and it’s already taken longer than 20 minutes…

After I create the bootable flash drive, can I easily transfer the installer to another flash drive (basically by drag n drop)? I installed it on a large 64gb flash drive, but it’s only taking up about 8gb. I’d like to move it to a smaller flash drive so I can use the 64gb for other files.

Or am I able to add on files with it to the 64gb?

Hi,

Before create the bootable usb, you can create a partition for it and a other for your files.

You can make it on Disk Utility when your usb stick is connected on your Mac.

Anthony Fassler -

Thanks for the reply, Anthony. But, I didn’t do that before I created the bootable usb. : ( Can I transfer the installer file from one usb to another?

Lori -

No, you can’t but, you can format your usb drive and create the partitions and for then create the bootable macOS on a partition.

Anthony Fassler -

Please, update the 1st step of the article - in Mojave there is no way to see a list of available OSs. I need a High Sierra image for my old iMac that is not booting up, and I can’t download it. Direct links to the OS update packages to AppStore are not working.
