Redesigned interface. Completely new. Completely Mac.

With OS X Yosemite, we set out to elevate the experience of using a Mac. To do that, we looked at the entire system and refined it app by app. Feature by feature. Pixel by pixel. And we built great new capabilities into the interface that put need-to-know information at your fingertips. The result is that your Mac has a fresh new look, with all the power and simplicity you know and love.

Mac and iOS are connected like never before.

Use a Mac or an iOS device, and you can do incredible things. Use them together, and you can do so much more. Because now OS X and iOS 8 enable brilliant new features that feel magical and yet make perfect sense. Make and receive phone calls without picking up your iPhone. Start an email, edit a document, or surf the web on one device and pick up where you left off on another. Even activate your iPhone hotspot without ever taking your iPhone from your pocket or bag.

Do everyday things in extraordinary ways.

One of the best things about a Mac is that it comes loaded with state-of-the-art, beautifully designed apps you’ll love to use every day. In OS X Yosemite, those apps give you new ways to do some of the things you do most. The apps you use to surf the web, read your mail, send messages, and organize your files and content have a simpler, more elegant look, and we’ve enhanced them with powerful new features.

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 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.
