Get your Mac ready for Mavericks (OS X 10.9)
Apple has released to developers the golden master of Mavericks (OS X 10.9)—the final non-public version, and most likely the build that will become the official 10.9.0. That means that the official public release of Mavericks isn’t far off. We’re still waiting on a specific date for that release—at WWDC earlier this year, Apple said only "this fall"—but for those aiming to upgrade as soon as the new OS drops, the golden master means that now is the time to start getting your Mac ready for Mavericks.
As with Mountain Lion (OS X 10.
last year, and Lion (OS X 10.7) before that, Apple is advertising Mavericks as a major upgrade that’s nevertheless simple to install. But as with every big upgrade to OS X, there are a few things you can do before upgrading to ensure that your Mac is ready to go.
What you need
Apple hasn’t officially released the system requirements for Mavericks, but from what we’ve seen so far, the new OS supports any Mac that works with Mountain Lion and is already running OS X 10.6.8 or later. That list of compatible models is:
iMac (Mid 2007 or newer)
MacBook (Late 2008 Aluminum, or Early 2009 or newer)
MacBook Air (Late 2008 or newer)
MacBook Pro 13-inch (Mid 2009 or newer)
MacBook Pro 15-inch (Mid/Late 2007 or newer)
MacBook Pro 17-inch (Late 2007 or newer)
Mac mini (Early 2009 or newer)
Mac Pro (Early 2008 or newer)
Xserve (Early 2009)
(Note that while the above computers should be able to install Mavericks, some features, such as Power Nap, AirPlay mirroring and extended desktop, and AirDrop, have stricter requirements.)
