Type your admin-level account password when prompted, and then press Return.

Paste the copied command into Terminal and press Return. Warning: This step will erase the destination drive or partition, so make sure that it doesn’t contain any valuable data.Launch Terminal (in /Applications/Utilities).Sudo /Applications/Install\ OS\ X\ Yosemite.app/Contents/Resources/createinstallmedia -volume /Volumes/Untitled -applicationpath /Applications/Install\ OS\ X\ Yosemite.app -nointeraction

Select the text of the following Terminal command and copy it:.

(The Terminal command I provide here assumes that the drive is named Untitled.) Also, make sure the Yosemite installer (or at least a copy of it), called Install OS X Yosemite.app, is in its default location in your main Applications folder (/Applications).

Connect to your Mac a properly formatted 8GB (or larger) drive, and rename the drive Untitled.

But I suspect that the vast ( vast) majority of people installing Yosemite will have access to a Mac running 10.7 or later. The only real drawback to createinstallmedia is that it doesn’t work under OS X 10.6 Snow Leopard-it requires OS X 10.7 Lion or later. Using it does require the use of Terminal, but it works well, it’s official, and the procedure is easy enough: If you can copy and paste, you can do it. Starting with Mavericks, hidden inside the OS X installer is a Unix program called createinstallmedia, provided by Apple specifically for creating a bootable installer drive. This time around, I’m sticking with a single method: using OS X’s own createinstallmedia tool. In my older Macworld articles on creating a bootable installer drive, I provided three, or even four, different ways to perform the procedure. If you don’t move or copy the installer elsewhere, you’ll need to re-download it to make your bootable installer drive. The reason is that when you install Yosemite, the installer deletes itself after installation finishes. One other important thing: After downloading the Yosemite installer, but before installing the new OS, you should either move the downloaded installer out of your Applications folder (which is where the Mac App Store puts it), or make a copy of it in another folder or on another drive.

Macworld has a nice tutorial that explains how to properly format the drive.

Your drive must be formatted as a Mac OS Extended (Journaled) volume with a GUID Partition Table. Your OS X user account must also have administrator privileges. You just need the Yosemite installer, which you download from the Mac App Store, and a Mac-formatted drive (a hard drive, solid-state drive, thumb drive, or USB stick) that’s big enough to hold the installer and all its data. (And don’t forget that not all Macs have OS X Recovery.) What you needĬreating a bootable Yosemite installer drive is actually pretty easy.

In fact, I think it’s a better emergency disk than OS X Recovery, because a bootable installer drive includes the full OS X installer, whereas OS X Recovery requires you to download 5+ GB of installer data if you ever need to reinstall the OS. It also serves as a handy emergency disk if your Mac is experiencing problems. 1 It’s great for installing the OS on multiple Macs, because you don’t have to download the 5+ GB installer onto each computer. I’ve long recommended creating a bootable installer drive-on an external hard drive or a thumb drive (USB stick)-for the version of OS X you’re running on your Mac.
