How to make your own bootable OS X 10.11 El Capitan USB install drive

It was 2009 when Apple last released a new operating system on physical media. Things have proceeded remarkably smoothly since version 10.7 switched to download-only installers, but there are still good reasons to want an old, reliable USB stick. For instance, if you find yourself doing multiple installs, a USB drive may be faster than multiple downloads (especially if you use a USB 3.0 drive). Or maybe you need a recovery disk for older Macs that don't support the Internet Recovery feature. Whatever the reason, you're in luck, because it's not hard to make one.

As with last year, there are two ways to get it done. There's the super easy way with the graphical user interface and the only slightly less easy way that requires some light Terminal use. Here's what you need to get started.
  • A Mac that you have administrator access to, duh. We've created El Capitan USB stick from both Yosemite and El Capitan, but your experience with other versions may vary.
  • An 8GB or larger USB flash drive or an 8GB or larger partition on some other kind of external drive. For newer Macs, use a USB 3.0 drive—it makes things significantly faster.
  • The OS X 10.11 El Capitan installer from the Mac App Store in your Applications folder. The installer will delete itself when you install the operating system, but it can be re-downloaded if necessary.
  • If you want a GUI, you need the latest version of Diskmaker X app. Version 5 is the one with official El Capitan support...

  • Once you've obtained all of the necessary materials, connect the USB drive to your Mac and run the Diskmaker X app. The app will offer to make installers for OS X 10.9, 10.10, and 10.11, and it should run on OS X versions all the way back to 10.7—support for 10.6 was dropped in the most recent release.

    Diskmaker X has actually been around since the days of OS X 10.7 (it was previously known as Lion Diskmaker), and it's still the easiest GUI-based way to go without intimidating newbies. If you're comfortable with the command line, it's still possible to create a disk manually using a Terminal command, which we'll cover momentarily.

    Select OS X 10.11 in Diskmaker X, and the app should automatically find the copy you've downloaded to your Applications folder. It will then ask you where you want to copy the files—click "An 8GB USB thumb drive" if you have a single drive to use or "Another kind of disk" to use a partition on a larger drive or some other kind of external drive. Choose your disk (or partition) from the list that appears, verify that you'd like to have the disk (or partition) erased, and then wait for the files to copy over. The process is outlined in screenshots above.

    The only slightly less-easy way

    If you don't want to use Diskmaker X, Apple has actually included a terminal command that can create an install disk for you. Assuming that you have the OS X El Capitan installer in your Applications folder and you have a Mac OS X Extended (Journaled)-formatted USB drive named "Untitled" mounted on the system, you can create an El Capitan install drive by typing the following command into the Terminal.

    sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction

    The command will erase the disk and copy the install files over. Give it some time, and your volume will soon be loaded up with not just the OS X installer but also an external recovery partition that may come in handy if your hard drive dies and you're away from an Internet connection.

    Whichever method you use, you should be able to boot from your new USB drive either by changing the default Startup Disk in System Preferences or by holding down the Option key at boot and selecting the drive. Once booted, you'll be able to install or upgrade El Capitan as you normally would.

OS X El Capitan Download Available For Apple Inc. Mac Desktops Starting Wednesday

Apple's latest desktop operating system, OS X El Capitan, can be downloaded through the Mac App Store

Apple’s desktop computers are getting a software upgrade. Starting Wednesday, Mac owners can download the latest version of its desktop operating system: OS X El Capitan.

The follow-up to OS X Yosemite comes with a number of small and large changes, ranging from a split-view feature that lets users view apps side-by-side to a new Notes app that can add photos, PDFs and videos. One of the biggest changes in El Capitan is a revamped Spotlight search, which goes beyond searching for files. With the update, Spotlight can be used to check stock prices, weather forecasts, sports schedules and more.

“People love using their Macs, and one of the biggest reasons is the power and ease-of-use of OS X,” said Craig Federighi, Apple's senior vice president of software engineering, in a statement. “El Capitan refines the Mac experience and improves performance in a lot of little ways that make a very big difference. Feedback from our OS X beta program has been incredibly positive, and we think customers are going to love their Macs even more with El Capitan.”

Other changes to OS X include a system font change to the San Francisco typeface, which is also used in iOS 9, tvOS and watchOS. San Francisco replaces Helvetica Neue, which was used in OS X Yosemite. El Capitan also comes with more support for international languages, including a new Chinese system font with 50,000 designed characters and support to transform Hiragana into written Japanese text. Beyond aesthetic changes, Apple claims El Capitan brings performance improvements to the Mac -- up to 50 percent faster system-level graphics rendering to speed up apps.

OS X El Capitan will be available for download through the Mac App Store. Apple’s latest version of OS X supports all Macs introduced in 2009 or later. Some models introduced in 2007 and 2008 are also compatible.
