Just a few months ago, Apple announced their latest OS X Mountain Lion at WWDC. With new features across the board such as Notification Center and iMessages, users have been anticipating its release. Apple has released the golden master build for OS X Mountain Lion and has officially announced which Macs will be supported by their newest operating system. Macrumors has provided a list for supported Macs: 

Your Mac must be one of the following models: 

- 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)

It is unfortunate for users who have been waiting so anxiously to be disappointed. On the bright side, this could be a reason for you to upgrade to the latest and greatest Macbooks. Without an official release date for Mountain Lion, we can expect it to be within the next few weeks.
