Go to your Apple menu, select About This Mac, and look for the Memory listing to see how much RAM your Mac has. If you’re not sure how much memory or available storage your Mac has, it’s easy to find out. Apple confirmed that your Mac requires 2GB of RAM and 8GB of free storage space for the installation. Luckily, if you’re already running Mavericks (Mac OS X 10.9) on your Mac, that same Mac is compatible with Yosemite-Mavericks and Yosemite have the same system requirements. But before you begin the installation process, there’s one question you need to answer: Can your Mac actually run Yosemite? Now that OS X Yosemite has officially stepped out of public beta mode and into prime time, I’m sure you’re itching to give it a go.
