Hi,, i have late 2013 iMac 27" i tried to install elcapitan from the app store,, installation didn't complete, and after that i can't boot into Yosemite anymore!! i tried internet recovery and i left it for 2 days and nothing has changed, so i decided to make el capitan usb installer in "vmware" using windows and (DiskMaker inside Virtual machine) then boot into it and try to reinstall El Capitan OS X.. after i booted into the installer partition and apple logo has appeared and progress bar has completed i got this &%$# SIGN!

Hi GForcee,

That sign means the system has found your bootable installer of Mac OS X on the system, but there is something wrong with it. Some critical system files are missing. If Internet Recovery Mode was the only one you could boot into and even that didn't work (can sometimes be fixed by using an Ethernet cable rather than relying on wifi), then you're on the right track with a USB installer...

If you have access to an OS X Terminal utility from your VMWare virtual machine - then you should create it with the createinstallmedia command based on the following example:

sudo /Applications/Install\ OS\ X\ 10.11\ Developer\ Beta.app/Contents/Resources/createinstallmedia --volume /Volumes/ElCapInstaller --applicationpath /Applications/Install\ OS\ X\ 10.11\ Developer\ Beta.app --nointeraction

If you can't run Terminal from VMWare, then I recommend using SuperDuper (which I know works for this) instead of DiskMaker, which I read failed for others too.

Let me know if this answers your question 🙂

Max.
