Create a Bootable Yosemite USB Installer with Terminal

Are you looking to create a bootable Yosemite USB installer? Creating a bootable USB drive for OS X's Yosemite operating system can be a bit of a process, but it's relatively easy and can be done using Terminal. In this step-by-step guide, we'll show you how to create a bootable Yosemite USB installer with just a few simple commands.

Step 1: Prepare the USB Flash Drive

Before you start, make sure you have a USB flash drive that is at least 8GB in size and is empty or has no important data on it. You can use Disk Utility to format the drive as Mac OS Extended (Journaled) and give it the name 'Untitled'. This will erase all contents of the USB drive, so make sure to back up any files you want to keep.

Step 2: Obtain the Yosemite Public Beta Installer

If you're registered for the Yosemite beta program, download the OS X Yosemite Public Beta installer from the Mac App Store. Once downloaded, it will launch the Yosemite installer app and put a file called Install OS X Yosemite Beta.app in your /Applications folder.

Step 3: Create the Bootable Yosemite USB Installer with Terminal

Open Terminal from the /Applications/Utilities folder and enter the following command:

```

sudo /Applications/Install\ OS\ X\ Yosemite\ Beta.app/Contents/Resources/createinstallmedia –volume /Volumes/Untitled –applicationpath /Applications/Install\ OS\ X\ Yosemite\ Beta.app –nointeraction

```

Press Return to execute the command, and enter your admin password when requested. This will create a bootable Yosemite USB installer on your flash drive.

Step 4: Wait for the Process to Complete

The process of creating a bootable Yosemite USB installer can take some time, depending on the speed of your flash drive. Let the tool do its thing and don't interrupt the process until you see Terminal output 'Done' and return to the user prompt.

And that's it! With these simple steps, you should now have a bootable Yosemite USB installer ready to use.
