Apple rebranded Mac OS X as MacOS on Monday at the company's annual Worldwide Developers Conference. In addition to changing the name of its Mac operating system, Apple dropped support for a number of Macs, the first time it has adjusted the hardware requirements for a Mac OS release since 2012 with OS X 10.8 Mountain Lion.

According to a slide at the end of Craig Federighi's MacOS presentation at the WWDC keynote, the following models will support MacOS Sierra:

  • MacBook -- late 2009 and later
  • MacBook Air -- 2010 and later
  • MacBook Pro -- 2010 and later
  • iMac -- late 2009 and later
  • Mac Mini -- 2010 and later
  • Mac Pro -- 2010 and later

From OS X 10.8 Mountain Lion to OS X 10.11 El Capitan, Apple's hardware requirements were:

  • MacBook -- late 2008 aluminum/early 2009 and later
  • MacBook Air -- late 2008 and later
  • MacBook Pro -- mid/late 2007 and later
  • iMac -- mid 2007 and later
  • Mac Mini -- early 2009 and later
  • Mac Pro -- early 2008 and later

This change leaves the following models out in the cold for MacOS Sierra:

  • MacBook from 2008 and early 2009
  • MacBook Air from 2008 and 2009
  • MacBook Pro from 2007, 2008 and 2009
  • iMac from 2007, 2008 and early 2009
  • Mac Mini from 2009
  • Mac Pro from 2008 and 2009
