Sometimes I get this message at the end of the installation thumbdrive making process:įailed to copy kernelcache, The file “kernelcache” couldn’t be opened because there is no such file.

So the error can be either on the installation or the thumb drive itself (bad drive).

When I install using terminal, I get this message at the end of the process, in terminal:Ĭouldn't mount dmg /Volumes/Install OS X El Capitan/Install OS X El Capitan.app/Contents/SharedSupport/InstallESD.dmg (error code 112)Mount of outer dmg failed.Īfter this, when I ran the hdiutil: hdiutil verify Install\ OS\ X\ El\ Capitan.app/Contents/SharedSupport/InstallESD.dmgĬhecksumming Protective Master Boot Record (MBR : 0)… Protective Master Boot Record (MBR :: checksum failed with error 1000.

My thumbdrive is detected inside El Capitan and I can make it bootable and put El Capitan installation on it by using terminal command: sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia -volume /Volumes/Untitled -applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app -nointeractionīut thumb drive is not visible when I hold option on restart. I am using OS X El Capitan on Macbook 7.1 (Mid-2010).
