Create a bootable USB drive for El Capitan

Create a bootable USB drive for OSX El Capitan

Everytime when Apple releases new software, I can’t help it to format my computer. I just don’t seem to trust an update of a operating system. I like to create a bootable USB drive because it’s blazing fast to install the OS. For El Capitan, it took me +- 15 minutes with a USB3 stick.

Luckily it is fairly easy to create a bootable USB drive for OSX El Capitan!

Create a bootable USB drive

  • Have a USB stick ready (USB3 is really fast! :-))
  • Format it with the Disk Utility tool (Mac OSX extended format, give the drive the name Untitled)
  • Download OSX El Capitan from the Mac App Store, but quit the update application when it is downloaded.
  • Open Terminal
  • Use the following command

  • Type in your password when asked
  • Wait a little while the files are being copied to your USB stick
  • TAKE A FULL BACKUP OF YOUR IMPORTANT FILES
  • Reboot your computer and hold the alt key
  • You’ll see a menu where you can choose to run the installer from the USB drive

Done 🙂

    Dus er is geen stap nodig waar je daadwerkelijk je hard drive moet formatteren ?

    • jawel eenmaal je in de installer zit, kan je kiezen voor ‘Disk Utility’ en dan daar je HD formatteren. Daarna kan je gewoon verder gaan met de install.

        Ah, perfect ! Had hem nu gewoon geüpdatet naar El Capitan.
        Maar loopt niet vlot ( enkele preference opties willen niet openen, trage opstart, ‘nieuwe’ spinwheel of death, … Ga hem nu proberen via clean instal.

        Thanks
