Mac OS X Yosemite is a whole new world [1] for your computer. Text everyone in your Contacts [2] from a Mac, get extra storage through iCloud Drive [3], and enjoy an updated Safari [4]. But before you start the download, follow these steps to ensure the upgrade goes off without a hitch.
Verify Your Apple Device
OS X Yosemite will only run on the following Apple products:
- iMac (mid-2007 or newer)
- MacBook (late 2008 Aluminum, 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)
Check System Requirements
- Must have OS X Mavericks, Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed on computer
- At least 2GB of memory
- At least 8GB of disk space
Back Up Your Computer
Just in case, it's always ideal to back up your Mac's data with Time Machine before downloading a new operating system.
Once your computer is ready to go, start downloading Yosemite from the App Store [5].
