How to Upgrade to Mac OS X Yosemite

The latest version of Mac OS X 10.10 (Yosemite) offers a lot of new features, including a new design and the ability to make iPhone calls from your browser. Fortunately, this upgrade won't cost you much time or any money. Here's how you can upgrade to Yosemite from OS X Snow Leopard (10.6.8) or higher. In addition to a few minutes of your time, you will  need 2GB of memory and 8GB of available disk space.

1. Check your system hardware and software by going to the apple menu, and choosing “About this Mac.”

2. Click on the “More Info...” button. Mac OS X Yosemite requires Mac hardware from no later than 2007 to 2007. Visit for more info.

3. Visit the Mac OS X Yosemite page on the Apple App store.

4. Click on the Download button to start downloading OS X Yosemite.

5. Click on the Free button and enter your Apple ID username and password to start downloading OS X Yosemite.  This will take several minutes, and it will first close out all your open apps and restart.
