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

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

    Александр - 回复

    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 - 回复

    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 - 回复

    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 - 回复

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

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

    ChingChangChong Chong - 回复

    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 - 回复

    Pretty good guide, especially for a community member. Thanks

    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 - 回复

    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?

You mean create a USB key from Windows ?

Anthony Fassler -

I'm thinking of using this method to revert back to an older os due to my mac slowing down with Sierra. Will I be able to install just Yosemite or el capitan? Without installing previous os upgrades? This way I can have a fresh mac book.

skylerzanth - 回复

Hello,

Yes you can but with this method, we must make a clean install.

So, please sure you save all your data to another hard drive.

Marc Pitchebai - 回复

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 - 回复

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. I feel like my youth playing with LEGO Technics has somehow contributed for my success, but this site was wonderful in all its simplicity!

wshifty - 回复

I have followed directions (trying to make a boot-able flash drive with High Sierra which was downloaded from Apple App Store and in my Applications folder, I am running El Capitan on my MacBookPro)

but get this in Terminal: “Untitled is not a valid mount volume”.

“Untitled” is the name of my 16GB USB flash drive, erased and configured as Mac extended journaled with GUID partition and renamed as “Untitled”:

any advice?

Alan Goldsworthy - 回复

Hello,

Did you copy paste of the command line ? Because, the command line is case sensitive.

Anthony Fassler -

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 - 回复

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…

Katrina Evitts - 回复

It’s written above Time Required 30 minutes - 2 hours.

It depends on the speed of the usb.

If yes, the command line you entered is incorrect. Copy and paste is the better option.

I’ve noticed a lot of people having issues so here is what I done first open terminal and type sudo then a space then go to your OS X app (should be in the application folder) and right click then choose show package contents after that a new Finder window will open double click Contents then Resources and find a file called createinstallmedia and drag it into your terminal window then type a space then “--volume” space then drag then name of your flash drive (should be listed on desktop) to the terminal window then type space then “--applicationpath” space then drag the installer app (should be in the application folder) to the terminal window then hit enter type your password hit enter “y” to confirm then enter
