Creating a bootable OS X installer isn’t as simple as it used to be, and things are a little bit more complex with the Developer Preview of OS X Yosemite.While there are multiple methods that will work, here’s the easiest way to create a bootable OS X 10.10 Yosemite USB Installer. The workaround is to create a bootable USB flash drive containing the OS X Yosemite installer. While it's easiest to use a USB flash drive as the destination for the installer, you can use any bootable media, including hard drives, SSDs, and USB flash drives.

There are many ways that you can create a bootable Mavericks USB Drive but this seems to me the far easiest way to do so. In this article I will assume that you already have a reasonable grasp of the OSX system and cut out the lengthy text:
1. Download Yosemite from the Apple Store
Yosemite can be downloaded directly from Apple Store here. After download it will try and install automatically on your Mac. Just cancel out of this.
2. Verify the Installation Files are present
Head over to your Applications folder and check that there is a file which says Install Yosemite
2. Prepare a USB Flash Drive (Must be 8Gb or larger)
- Plug the USB Drive in to your Mac and open “Disk Utility” (found under applications / utilities in finder)
- Select the USB Drive
- Select the Erase tab
- Ensure that the format is Mac OS Extended (Journaled)
IMPORTANT – Leave the name as “Untitled”. If you change this the next step won’t work
3. Create the Bootable Yosemite USB Drive

The all now OS X 10.10 Yosemite is out now and its a free upgrade like Mavericks. It’s very simple task to upgrade an exsisting os to Yosemite with “App Store”. It’s actualy one click away from Yosemite. But if you need to install a fresh copy of Yosemite into your macbook, you will need either a DVD installer or a Bootable Yosemite installer.
Why a fresh install
Many people says slow issues after upgrading to old version Mavericks. And after upgrading some of your already installed apps wont work. Keeping a USB installer drive is a good idea to use it for recovery or troubleshooting purposes. And if you have one bootable installer, you can use it with your other Macs to install the Yosemite. It really really helps you by avoiding downloading the Yosemite installer file in each Mac.
What to backup
Before you start installing Yosemite, you should backup all the important data to an external resource. Installing the OS X is a kind of formatting your Mac. The process will wipe out the entire Hard disk. And more thing, you done need to backup or note a product key like windows product key in your mac. Mac doesn’t ask any product key while installing. Your Apple hardware is the product key for all your OS X installations.

OS X Yosemite hardware requirements
You should check wether your current hardware is compatible with Yosemite. Minimum ram required for Yosemite is 2GB. But 4 GB or higher is recommended for best performance. A hard disk space of 40GB is recommended for installing Yosemite with ease. Please note your entire HDD will wipe out while installing the Yosemite.
- Macbook air late 2008 or later
- Macbook Pro mid 2007 or later
- Mac mini early 2009 or later
- iMac mid 2007 or later
- Mac Pro 9 early 2008 or later
Making a USB installer is an easiest task if you already downloaded the Yosemite installer “.App” file. For downloading the file you should go to the “App Store” and then select the “Updates” tab on the top right position. Click on the “free upgrade” option for downloading the Yosemite installer file. The app file size will be 5.16GB as i can see here. Now the installer file is downloading to the /Applications directory.
You need a 8GB or higher capacity USB pen drive which formatted as “Mac OS Extended (journaled)”
Prevent auto deleting the downloaded file
After completing the download you should copy the downloaded file from /Applications directory to somewhere (i.e. to desktop). Because the downloaded file will automatically delete after starting the automatic upgrade process. Make sure you copied to a different directory. The downloaded file name and extension should look like Install OS X Yosemite.app. Now you are not far from create bootable usb of yosemite.
