Create Install Media Yosemite

Locate the file named Install OS X Yosemite, and then right-click the file and select Show Package Contents. Open the Contents folder, then open the Shared Support folder. Here you will find the disk image that contains the files you need to create a bootable installer. Double-click the InstallESD.dmg file. Doing so will mount the InstallESD. A bootable installer is one of the fastest ways to install Mavericks. Rather than copy the installer to a local drive you can run it right off a USB disk (or Thunderbolt if you dare). Such a little USB drive would be similar to the sticks that came with the older MacBook Air, when we Continue reading Create Mavericks Installation Media. You can use an external drive or secondary volume as a startup disk from which to install the Mac operating system. If you're interested in running Mac OS X, but you don't want to pay ridiculous prices for a normal Mac, then a Hackintosh just might be fo.

Apple stopped making their software available on CD/DVD ages ago. Applications including the entire OS is downloaded only through their App Store.

When you download and install the OS from their App store, it performs an upgrade to the existing operating system. Your applications and a large majority of your settings are preserved. But what if you want to perform a clean install? Wipe everything off and start anew? Well to do that, you'll need to have the installer on another media. Such as another hard drive you can connect to, a CD/DVD, or flash memory (thumb drive, SD card, etc.).

To transfer the OS installer to a secondary storage media requires more than just copying the installer to the media. It has to be bootable. You will need to install the OS on the secondary media. The general method is to format the target destination (flash memory, hard drive, etc.) and run the installer on the target.

createinstallmedia is an easy way of installing the operating system to the secondary storage media. This was introduced in Mavericks. (Unfortunately I didn't know about it until now because I skipped Mavericks.) createinstallmedia is packaged in their OS installer. There is no need to download it separately. createinstallmedia is a program that needs to be run in Terminal.

There are numerous tutorials available online (video and writeup). From what I've read and seen, the steps require downloading the OS installer, formatting the target media, copying the code and pasting into Terminal, and then executing the code. The tutorial steps are straight forward. If you don't deviate from them, then you will succeed with a bootable system.

For my tutorial, I'm targeting the command line averse. The method I employ gives more leeway. For example, the majority of the tutorials online have you download the installer from the App Store and leave it alone (that is, don't move it from the Applications folder). Well, say you've downloaded the OS already and have is stored in another folder or another volume (a different hard drive)? If you try to execute the command based on their tutorial, it will fail because the path is wrong. The method I use will ensure the path is filled out correctly. I'm using a USB flash/thumb drive as my target destination, but this should work on any other form of flash memory or external hard drive. The only caveat is the target destination must be large enough to accept the OS (min is about 6GB; 8GB is ideal).

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.

Create Install Media Yosemite

• A Mac, duh. We've created Yosemite USB from both Mavericks and Yosemite, 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 10.10 Yosemite 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—we wrote this article based on version 4 beta 2, but if a 'final' version is released alongside Yosemite we'll update the article. This app is free to download, but the creator accepts donations if you want to support his efforts.
• An administrator account on the Mac you're using to create the disk.

The easy way

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 10.8, 10.9, and 10.10, but we're only interested in Yosemite today.

Diskmaker X has actually been around since the days of OS X 10.7 (it was previously known as Lion Diskmaker), but it's more important now because Apple has made alterations to the installer that prevent easy USB drive creation using the built-in Disk Utility app. It's still possible to create a disk manually using a Terminal command (which we'll go into momentarily), but Diskmaker X presents an easy GUI-based way to do it that is less intimidating to most people.

Select OS X 10.10 in Diskmaker X, and the app should automatically find the copy you've downloaded to your Applications folder. If it doesn't detect the installer (or if you click 'Use another copy'), you can navigate to the specific installer you want to use. 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 below.

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 Yosemite 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 a Yosemite install drive by typing the following command into the Terminal.

sudo /Applications/Install OS X Yosemite.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install OS X Yosemite.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 Yosemite as you normally would.
