Can't really see how I can do this procedure wrong. Is does mount as it should on my desktop, though, and I'm able to run the installer from the USB. However, the install-USB is not bootable and does not show up i the 'Startup disk preference panel'. As I've done a thousand times before I created an install-USB by downloading El Capitan from the App Store and compiled it on to the USB-drive by using Apples own terminal command. I have decided to go with a fresh and clean install of OS X 10.11 El Capitan this time. Heres what I've tried so far: - Redownloading El Capitan from the App Store (if something was wrong with the first image) - Tried creating the USB on three different Macs (with Mavericks, Yosemite and El Capitan) - Tried creating the USB by using Diskmaker X 5.0.1 instead of the terminal command (on three Macs) - Formatting the USB a thousand times (GUID / OS X - journaled) - Testing the USB on four different Macs - none of them recognizes the USB as bootable So what do you wise people say? Why can't I create a bootable OSX-install-USB like before?
