El Capitan but converts the InstallMacOSX.pkg to the Install OS X El Capitan.app which will appear
in your Application folder, it is this you use to create the bootable USB installer.
You can only do this on Macs that can install El Capitan, any Macs that came new with macOS Sierra
or a later OS preinstalled will not be allowed to convert the .pkg to the Install OS X El Capitan.app.
This is pretty dumb of Apple, as many Mac owners might need to use newer Macs to create bootable
installers for older Macs that have experienced difficulties.

I’m trying to sell a 2009 MacbookPro. It’s the model MacbookPro5.5 and Apple supports macOS El Capitan 10.11 as latest available version.
I’ve wiped all data from the installed SSD and had to boot from an external disk. Now I’ve got two problems:
- I’ve only got a Mac with Big Sur and Apple Silicon. I cannot use the package installer from the download provided by Apple to create the installer App for El Capitan. However, I need access to the installer so that I’m able to use the createinstallmedia command.
- The 2009 MacbookPro is already wiped and has only access to the recovery mode. You cannot execute the package installer in Recovery Mode to extract the media.
Luckily I’ve found this blog post from Chris Warrick who explained how to extract the installer App from the package: Ford tractor serial number c5nn.
- Attach an external Disk which contains the downloaded pkg from Apple. You’ll need enough space on that Disk to extract the pkg and it needs to be writeable
- Open the Terminal from inside the Recovery Mode
- Go to the mounted volume
- Extract the package:
Now we can try to create the install media from the installer app. Make sure you’ve attach another disk which can be overwritten by the installer. In this example its named „MyBlankUSBDrive“:
The InstallESD.dmg image is missing, which we’ll need to add to the right location:
Install El Capitan Without App Store
Now we’ll have a valid installation medium which can be used to start the installer from. You can reboot from that disk and should be able to install El Capitan.
However, I’ve encountered another annoying issue which caused the installer to fail:
Os X El Capitan App
El Capitan Installer cannot be verified
Oh great… On to the next commands you can try from the Terminal inside the Recovery OS:
Apple Download El Capitan Installer
installer -pkg /Volumes/Mac OS X Install DVD/Packages/OSInstall.mpkg -target /Volumes/'XXX'where XXX is the name of the disk you’re installing to.- Wait for the installation to say it’s complete. You will not see any sort of progress display.
Install Os X El Capitan App
Great, you’ve got El Capitan installed! Apple had some issues with certificates and people found a way to either use the above commands for installation or you’ll have to tinker with your Macs time settings so that the signature is valid again. I would have expected that Apple resigned all installers so I wouldn’t have to use these commands at all but doesn’t look like they did.
