Jun 05, 2014 Apple released the new Mac OS X 10.10 Yosemite in the Mac App Store for everyone to download and install for free on October 16th, 2014, but downloading a 5+ GB file for each of your computers will take some serious time. The best thing to do is download it once and create a bootable install USB drive from the file for all of your Macs.

Those who are facing performance issues with direct upgrade via App store or installing OS X for the first time on their Macs can follow a simple step-by-step guide to perform a clean install of Yosemite using Disk Utility.

Before we delve into the detailed process of clean installing OS X Yosemite on Macs, there are a few things that need to be taken care of.

Prerequisites

a) Ensure your Mac is compatible with OS X Yosemite. These are the supported devices:

  • iMac (Mid 2007 or newer)
  • MacBook (Late 2008 Aluminium, or Early 2009 or newer)
  • MacBook Pro (Mid/Late 2007 or newer)
  • MacBook Air (Late 2008 or newer)
  • Mac mini (Early 2009 or newer)
  • Mac Pro (Early 2008 or newer)
  • Xserve (Early 2009)

b) Back up important data and settings (photos, videos, music files, documents and the like) on your Mac to an external hard drive. You can do this by using the Time Machine feature in Mac OS X, or third-party software such as Carbon Copy Cloner.

c) Create a bootable USB flash drive with a storage size of at least 8GB.

d) Download OS X 10.10 Yosemite Final from the Mac App Store and save it to the Applications folder – its default location.

How to Create Bootable USB Flash Drive

First, create bootable USB flash drive. Here is how you do it, courtesy of Redmond Pie:

  • Plug in your USB drive into the computer and open Disk Utility (in Applications).
  • Select the USB drive from the left sidebar and click on Erase tab.
  • Choose Mac OS Extended (Journaled) in the format box and let the name be Untitled (default).
  • Now click on Erase button and wait until the format process completes.
  • Then choose Partition tab and select 1 Partition from Partition Layout dropdown menu. Click on Option and ensure GUID Partition Table is selected as the partition scheme, with its name set to Untitled.
  • After downloading the OS X 10.10 Yosemite instakker from the Mac App Store, just quit the installer and set the downloaded file's name to Install OS X Yosemite.app.
  • Launch the Terminal app (in Applications/Utilities) and type or paste the following command in, and then hit Enter:

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

  • This will create the bootable USB flash drive. This takes between 10-20 minutes. Do not interrupt the Terminal or eject the flash drive during the process. Once the process completes, you will see the message 'Copy Complete. Done.'

The OS X Yosemite bootable USB flash drive will be ready for use and you can start the clean installation process.

How to Clean Install OS X Yosemite on Your Mac

Step 1: Ensure the bootable USB flash drive is plugged into your Mac and restart the computer. As soon as the start-up chime plays, press the Option key (Alt).

Step 2: Choose the USB drive on the start-up drive selection screen and hit Enter/Return on the keyboard.

Step 3: Wait until the Yosemite installer appears on screen. This could take a few seconds or minutes.

Step 4: Click on Disk Utility and then hit Continue.

Step 5: Click on Macintosh HD from the left hand-side pane and then hit Erase tab on the top-right portion of the window. Leave all the settings at their default values and then hit Erase button at the bottom right. This will wipe all files stored on your startup hard drive.

Step 6: When the erasing process is complete, return to the first screen where you selected Disk Utility. Now click on Install OS X and then hit Continue.

Step 7: Choose the Macintosh HD partition you erased in step 5 and then click Install.

If you have followed all the steps correctly, your computer should now boot right into the newly installed operating system, OS X Yosemite, and you could cherish its stunning new UI.

Mac Os X Yosemite Features

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
