Creating USB installers for older versions of Mac OS X can be tricky, so I decided to put together a more detailed walkthrough. High Sierra is similar, but you actually want to use a different date timestamp!
El Capitan Create USB Command:
sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/el-cap --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app
El Capitan Date Change Command:
Date -u 0923020415
High Sierra Date Change Command:
date -u 0818025919

Brother Thank you so much 😊. You covered every steps that needed to be done for this process to work. I lost a lot of time trying to figure it out from others.
Thank you! After 2 days of trying different methods, yours was the only one that worked.
Glad to hear!
Nothing else worked, but these instructions were clear, perfect and useful. Thanks!
Thanks dude your video was so helpful... Was able to recover my old 2009 MacBook Air👍🏻
Thank you! This video was VERY helpful. I had some issues along the way but have been getting them sorted out! Bought a 2009 iMac for basically nothing at all and am trying to fix it up as it was broken in the previous owners eyes.
BRILLIANT, cheers very much mate!
You’re awesome, I’ve just been able to get this done finally....it took me longer tho but I did it.
You are a life savior! Thank you so much!!!
Such a great video. thanks for the help!
Glad it was helpful!
I have an official El Capitan installer but each time I try to install I got this annoying error message: "This copy of the Install OS X El Capitan application can't be verified...". Any idea on how to solve this issue? Thx [ Problem solved. You have to input the date of the day you downloaded the .dmg from Apple]
Very helpful, thx a lot :-)
@Powergeek2011 LEGEND!!!!! thank you i've been trying to sort this out for DAYS
It works on me. Thank you so much bro :)
you were so helpful
There's one important thing in the text string that you HAVE to change for this to work. In the string, his thumb drive is named "el-cap." You HAVE to change that to whatever you named your thumb drive when you format it.
Also, changing the date string to the one listed also caused issues - I changed it back to the current date and all was well and everything is working fine now.
very helpful... thanks
What version of macOS you had on your Mac when creating a Marcos El Capitan pls.. I’m trying to make a bootable for elcapitan on Mac OS Catalina it’s say command not found :(
Hey bro, thanks for the hack! but just a quick question on the date format. I don't quite understand it, could you please explain the format. cheers
where can I get the EL CAPITAN APP , i cannot run pkg installer
what If I don't have a working MAC book and I need to create a USB bootable for El Cap because of corrupted hard disk. Can I create a bootable usb for MAC OS X El capitan using windows pc?
i get this error . sudo /Applications/InstallOSXElCapitan.app/Contents/Resources/createinstallmedia--volume/Volumes/el-cap: command not found
me too!
THANX MAN!
You're welcome!
When i go into the startup boot menu thing it doesn’t bring up my USB only the recovery drive
It says "command not found" The only thing I can find on the internet is too vague to be helpful. Can you please help? Thank you so much! Doug
Hi! Trying to do this for my old MBP 2010. I am on OSX Catalina, and whenever I mount the el capitan installer, it wouldn't want me to open. It says warning. I can't mount it to the Application. Any recommendations?
I had to download an El Capitan image file (from where I cannot say...) and run it in VMWare (you can get a trial version that works fine). Then download the dmg from Apple within the virtual machine, unpack the pkg and finally create the install media from that file. All in the virtual machine. I tried several methods of unpacking the file using various terminal commands but the resulting installer simply wouldn't work. It was a real pain but I got there in the end.
Hi, where did you download the dmg with the El Capitan installer? When I get it off Apple's site it's a dmg with a pkg file in it. Thanks!
You have to install the app by executing the pkg, then an El Capitan APP installer will be created at the apps folder
@@ideasanli4925 Thanks but this only works if unpacking the pkg on El Capitan or older. In the end I had to download an El Capitan image file and run it in VMWare. Then download the file within the virtual machine, unpack the pkg and finally create the install media from that file. I tried several methods of unpacking the file using various terminal commands but the resulting installer simply wouldn't work. It was a real pain but I got there in the end.
@@MikeyC314 i just did this on My MacBook running Catalina to fix a 2009 MacBook with forbidden icon error, and worked, just did it yesterday
@@ideasanli4925 I install it and but does not show in app folder
good
when installation starts it prompts that "copy of install OS X El Capitan application can't be verified" and cancels the installation. I couldn't get terminal open (no "utilities" -tab at top panel, only "edit" and "window" shows up) while in install OS X, so I did it while in OS X utilities (prior to install OS X). Is this the cause of install error?
Yeah - you have to set the date in the installer or it will fail like you have mentioned.
@AI If you go with the mouse to the top of the screen you get a menu and you can disable the Wifi and then do the change on the date. Make sure you have unplug the network cable if you have it connected. then restart and it should do the installation. I wasted a ferw hours till I found this: apple.stackexchange.com/questions/394259/mac-stuck-in-el-capitan-installer-loop-no-packages-were-eligible-for-install
terminal on my end says el cap is not valid volume mount point
Running BigSur on my main machine, it is literally stopping me from doing anything. It's like I'm not supposed to fix my old iMac. I can't even get the installer to copy to a USB drive without error. (error code 100006). Just 1 road block after another. damn
got it to mount on another older computer, typed in the code now all I get is no file or directory found or some BS. Bangs head against wall.
Have all the stuff but it will not allow me to install OS X without being on the internet. So will not reinstall. I do get a reinstall on the internet but it will take 1,467,687 hours and 46 minutes?????? I have turned off the internet but it tells me it needs to be on the internet.
I still got an error this time saying “an error occurred while preparing the installation. Try running the application again “ I even set the the date to 1 month later
Like @Powergeek2011 mentioned in his comment : it seems to work with date of download too. in my case it was successful with a 2008 imac 24" installing el capitan. The format is Date [4Digit month day 4Digit Time 2 Digit year]. Thx a lot :-)
I have a brick now ….did everything right erased the hard drive to start installation ant when was starting to install said that the file El Capitan or complete was not compatible . And I don’t have mother Mac to do another pen you forgot to tell to disconnect the internet…. Important step
not working on Macbook Pro 17inch 2009
Given a Mac Pro 3,1. Made the USB boot following the instruction - All OK - but it won't boot up from it. Crashes halfway through loading at Apple icon. Your machine encountered a problem. It does this everytime. Good video though!
Hi its says that the install OS X APPLICATION can’t nbe verified. it may have been corrupted or tampered with during download
you need to do current month date time year eg. date -u 1113092220 and try it should work .
perfeito
not happening for me. I typed each letter and confirmed just like your sentence and followed the same naming and all I get is "no such file or directory" another dead end for me
Hi that code don’t work in terminal
thank you sir
What’s the link to the dog file bro
Can it not be a 4gb USB?
Not it has to be at least 8gb or it won't install. The dmg file is 6.2gb
How to install the dmg file
Did u find out
Hi when I put the link and my password this is what I am getting
/volume/el-cap is not a valid volume mount point.
Is it something I am doing wrong?
Kind Regards
You have to rename the memory stick without spaces, then where it says volume change his el-cap to the name you give it. I renamed mine Elcap. It found it and worked but it failed to install. So now I'm stuck.
