It can be quite easy making an update to the OSX 10.10 Yosemite from the Mac App store for one computer, but when it comes to making updates for several Macs, or even doing a fresh install, you might find it really stressful having to make those updates separately. One way to save yourself the hassle is grabbing the Mac update on a USB thumb drive and installing the update using same drive on all your Macs.

Create A Bootable Yosemite USB. Step 1: The user will need to download OSX Yosemite from the link is given above in the article. Step 2: The user will need to make a USB Drive that is bootable. To get that, the following needs to be done. Insert a high memory USB Drive. Yosemite Bootable Usb Download Software; Yosemite Bootable Usb Download.

It is important to note that running the Yosemite update on your Mac before following the below procedures would erase the installer from your Applications folder. So it is necessary you firstly perform this tutorial using any of the below methods, unless you wish to download a fresh copy of the update again from the app store. Let’s move on to the tutorial.

Things You’ll Need

• A Mac
• An 8GB USB Flash Drive or larger where you would be burning the OSX Yosemite copy to.
• The OS X 10.10 Yosemite installer from the Mac App Store in your Applications folder
• An Administrator account on your Mac

Method 1: Using DiskMaker X

Using Diskmaker X is the easiest way to burn or make a bootable USB Flash drive. Here is how to go about it.

A little 'guide' about the creation of a bootable OsX 10.10 usb installer for the SurfacePro, this can be done on a Vm, another hack, or a real mac. For files and guide visit: http://www. 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. As you know, Apple releases a new OS X operating system every year, and the new OS X can only be downloaded via the Mac App Store (currently OS X Yosemite).

1. You need to download the Yosemite installer as stated above from the Mac App Store and DiskMaker X .

2. Insert your 8GB (or larger) flash drive into your MAC. Make sure you must have backed up all important stuff, as you will loose them in this process from the flash drive.

3. Launch DiskMaker X. The app will offer to make installers for OS X 10.8, 10.9, and 10.10. Since we wish to install Yosemite, you will have to select 10.10 and let DiskMaker X handle the rest. DiskMaker X would find the Yosemite Installer and have it installed on your thumb drive. If it doesn’t find it, you can click on “Select an Install File” so you can easily navigate to the installer.

After the whole process must have been completed, you can now use this flash drive to install OSX Yosemite to any MAC. It’s actually that simple.

Method 2: Using Terminal

If for some reasons you couldn’t get DiskMaker X working for you, you might want to follow this geeky steps using Terminal to achieve same result.

1. Firstly Download the Yosemite installer.

2. Insert your 8GB (or larger) flash drive (make sure you assign a name to it – I’ll be using Untitled as my drive name for this tutorial). Make sure you format your USB flash drive in OS X Extended (Journaled) using Disk Utility.

3. Launch the Terminal application on your MAC. Then type (or copy and paste) the following command into your Terminal window. Make sure you replace Untitled with the name of your drive. Then hit Enter on your keyboard.

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

4. Now you would be prompted to type in your password, then press Enter again.

Allow terminal to complete the process (this could take close to half an hour). You can take out your USB Flash when you get the Done prompt. After it’s done, you should be able to use your USB Flash drive as a bootable disk to install OSX 10.10 Yosemite on any MAC computer.

Note: The Bootable USB Flash drive would not only be used to install Yosemite on Mac computers, but would also have utilities like Disk Utility and Time Machine recovery.

To make use of this thumb drive to install the OSX 10.10 update, you can change the default Startup Disk in System Preferences or by holding down the Option key at boot and selecting the drive.

I hope you find this useful.

[3/7/2017 update: Just a reminder that Apple has released a good number of major updates to OS X 10.10 Yosemite since its initial release. Unfortunately, if you created an installer drive with an older version of the Yosemite installer, you can’t easily update the installer drive so that it installs the latest version of Yosemite. If you want to create a bootable drive that installs the latest version of 10.10 directly, you’ll need to download the latest version of the Yosemite installer from the Mac App Store, and then repeat the procedure below using that newer installer app.]

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.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. It also serves as a handy emergency disk if your Mac is experiencing problems. 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. (And don’t forget that not all Macs have OS X Recovery.)

What you need

Creating a bootable Yosemite installer drive is actually pretty easy. 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 [SSD], thumb drive, or USB stick) that’s big enough to hold the installer and all its data. An 8GB thumb drive is perfect. Your OS X user account must also have administrator privileges.

Your drive must be formatted as a Mac OS Extended (Journaled) volume with a GUID Partition Table. Macworld has a nice tutorial that explains how to properly format the drive.

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. The reason is that when you install Yosemite, the installer deletes itself after installation finishes. If you don’t move or copy the installer elsewhere, you’ll need to re-download it to make your bootable installer drive.

The best option: createinstallmedia

In my older Macworld articles on creating a bootable installer drive, I provided three, or even four, different ways to perform the procedure. This time around, I’m sticking with a single method: using OS X’s own createinstallmedia tool.

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. 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.

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. But I suspect that the vast (vast) majority of people installing Yosemite will have access to a Mac running 10.7 or later.

The steps

1. Connect to your Mac a properly formatted 8GB (or larger) drive, and rename the drive Untitled. (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).
2. Select the text of the following Terminal command and copy it:
3. Launch Terminal (in /Applications/Utilities).
4. Warning: This step will erase the destination drive or partition, so make sure that it doesn’t contain any valuable data. Paste the copied command into Terminal and press Return.
5. Type your admin-level account password when prompted, and then press Return.

The Terminal window displays createinstallmedia’s progress as a textual representation of a progress bar: Erasing Disk: 0%… 10 percent…20 percent… and so on. You also see a list of the program’s tasks as they occur: Copying installer files to disk…Copy complete.Making disk bootable…Copying boot files…Copy complete. The procedure can take as long as 20 or 30 minutes, depending on how fast your Mac can copy data to your destination drive. The process is finished once you see Copy Complete. Done., as shown in the screenshot above. If you like, you can then rename the drive (in the Finder) from its default name of Install OS X Yosemite.

Booting from the installer drive

You can boot any Yosemite-compatible Mac from your new installer drive. First, connect the drive to your Mac. Then, if your Mac is already booted into OS X, choose the install drive in the Startup Disk pane of System Preferences and restart; or, if your Mac is currently shut down, hold down the Option key at startup and choose the install drive when OS X’s Startup Manager appears.

Once booted from your installer drive, you can perform any of the tasks available from the OS X installer’s special recovery and restore features. In fact, you’ll see the same OS X Utilities screen you get when you boot into OS X Recovery—but unlike with recovery mode, your bootable installer includes the entire installer.

1. One of my favorite annual Macworld projects was writing a comprehensive installation guide for each year’s version of OS X. (Here’s last year’s OS X 10.9 Mavericks edition.) The most popular of those articles each year, by far, was my guide to creating a bootable OS X installer. Back in July, I wrote a version of that tutorial for pre-release versions of Yosemite; since I’m no longer at Macworld, I can’t update that article for the final release of Yosemite, so I’m publishing final instructions here. ↩
