I'm trying to follow tutorial over at: http://osxdaily.com/2015/06/11/make-bootable-os-x-el-capitan-beta-install-usb-drive/
to create bootable usb for El Capitan Public Beta, however after completion I get this error in console:
Mount of outer dmg failed.
I tried running
hdiutil verify /Applications/Install\ OS\ X\ El\ Capitan\ Public\ Beta.app/Contents/Resources/createinstallmedia
And it returned:
hdiutil: verify: unable to recognize "/Applications/Install OS X El Capitan Public Beta.app/Contents/Resources/createinstallmedia" as a disk image. (image not recognized) hdiutil: verify failed - image not recognized
I'm not sure why. I downloaded beta installer and it launched correctly. It sits in Applications folder.
