I have downloaded the El Capitan dmg file (InstallMacOSX.dmg) provided by Apple. The expanded dmg image contains the package 'InstallMacOSX.pkg' which should be run to create the El Capitan installer but fails with the following message 'This version of OS X 10.11 cannot be installed on this computer.' The copy of the installer app failed. MacOS install media creation exited with a not normal exit code, see previous lines in the log to get more info about the. With that version of Mac OS X, and all versions since, it's been possible to use the Terminal command createinstallmedia to create a bootable installer of the macOS, in this article we'll show you. Copy of install macOS application is damaged and can’t be used to install macOS. There is not enough free space on the selected volume. This guide will give you a detailed rundown of the most common macOS Catalina installation and update errors encountered by Mac users when upgrading or installing macOS Catalina, along with the instructions.
Now that Apple has released their Golden Master seed of OS X Mavericks to developers, the public release could happen at practically any time! With the Golden Master – which represents the final build that Apple will release publicly in the Mac App Store – Apple has changed the necessary steps required to build a fully functional bootable USB installer for the preview.
A USB install disc can be an important tool to quickly and easily install a fresh copy on your Mac, without first having to install OS X Mountain Lion and then upgrade using the Mac App Store method. Since Apple has changed a few things since their first developer preview, we’ve got a new method for creating a USB install disc also – and this one should work for many versions of OS X to come.
Note: While the old method still technically works, it will not install a Recovery Partition, whereas this new method will. Before you proceed, please note that you will need a flash drive at least 8GB in size or larger.
Here’s how to make it work, courtesy of some helpful instructions from MacRumors forum member tywebb13:

Your 8 GB USB drive should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install OS X Mavericks.app and should be in your Applications folder.
Run this in terminal and wait about 20 minutes:
sudo /Applications/Install OS X Mavericks.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install OS X Mavericks.app –nointeraction
You should see something like this:
Erasing Disk: 0%… 10%… 20%… 100%…
Copying installer files to disk…
Copy complete.
Making disk bootable…
Copying boot files…
Copy complete.
Done.
Copying installer files to disk…
Copy complete.
Making disk bootable…
Copying boot files…
Copy complete.
Done.
Patience is key. The process can take up to 20-30 minutes to finish, even though Terminal may not look like it is doing anything. Make sure to wait until you see the “Done.” prompt before exiting Terminal or interrupting the process.
That’s all there is to it! For reference, the original method of creating a USB boot drive can also be found below.

1. Show hidden files by opening /Applications/Utilities/Terminal.app and typing the following:
Macos Createinstallmedia The Copy Of The Installer App Failed Windows 10
defaults write com.apple.finder AppleShowAllFiles TRUE
killall Finder
2. Right click Installer.app file and click Show Package Contents, Open Contents folder, then look in SharedSupport folder. You will see InstallESD.dmg.
3. Mount InstallESD.dmg.
4. Copy the BaseSystem.dmg file out to somewhere convenient.
5. Do not mount BaseSystem.dmg. Just open Disk Utility and restore it to a flash drive.
6. When that’s done look in the flash drive you just restored to and go to /System/Installation/. In that folder you will see a white icon with an arrow called Packages. That’s a broken alias. Delete it.
7. Now go back to your InstallESD.dmg file. Inside is a folder weighing in at about 4.5GB called Packages. Copy that folder onto the flash drive in place of where the alias was.
8. Go ahead and hide the hidden folders again by going back to the Terminal and typing:
3. Mount InstallESD.dmg.

defaults write com.apple.finder AppleShowAllFiles FALSE
killall Finder
9. Done. Boot from the flash drive and get to work.
As per usual, don’t blame me if you screw up.
