Mac OS users who are already running Mavericks on their desktop computers are now eligible for free upgrade to OS X 10.10 – Yosemite.
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.'
