How To Burn OS X El Capitan To A USB Flash Drive

It s easy enough to upgrade to OS X El Capitan from the App Store, but downloading the software multiple times isn t a great idea if you have more than one Mac, or a Hackintosh. Here s how to burn El Capitan to a USB drive instead.

As with all OS X upgrades, once you run the installer on your system, it disappears from the Applications folder. You can get it back by holding down the Option key while clicking on the App Store s Purchases tab to re-download the file, but to save you time, it s best to put it on a USB before you update your Mac.

The Easy Option: Diskmaker X

How To Burn OS X El Capitan To A USB Flash Drive

As has been the case for the last few releases of OS X, the easiest method to make a USB install drive is with the free program, Diskmaker X.

It s been updated today to support El Capitan. As of this writing, it s only available in French, but the installer works the same either way.

  1. Download the El Capitan installer and Diskmaker X1.
  2. Insert an 8GB (or larger) flash drive. If you have any other data on that flash drive, back it up now, because the installer will delete everything on it.
  3. Start DiskMaker X, choose El Capitan from the list of options, and it ll handle the rest.

When it s done, you can insert your USB drive into any Mac and then launch the installer by holding down the Option key when you boot up your computer.

The DIY Option: Terminal

If you don t want to use Diskmaker, you can burn it for yourself with no extra software and a simple Terminal command.

  1. Download the El Capitan installer.
  2. Insert an 8GB (or larger) flash drive and give it a name.

    For this tutorial, we ll use the name Untitled. Make sure the drive is formatted for OS X Extended (Journaled). If it isn t, open up Disk Utility and format is so it is.

    Before you do so, back up any important data on that drive.

  3. Open up Terminal (Applications > Utilities).
  4. Type (or copy and paste) this command into Terminal, replacing Untitled with the name of your drive, then press Enter: sudo /Applications/Install OS X El Capitan.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install OS X El Capitan.app –nointeraction
  5. Type in your password when prompted and press Enter.
  6. Let the command line to its work and don t interrupt it until you see the final line that says Done.

    This can take up to a half hour, so be patient.

When it s done, you can insert your USB drive into any Mac and the launch the installer by holding down the Option key when you boot up your computer.
