If you have the old MacBook you plan to use as a backup is now the perfect time to upgrade it. After a decade, Apple will finally allow users to download Mac OS X Lion and Mountain Lion for free.
By Cult of Mac, OS X Lion was first released in July 2011, and Mountain Lion was introduced the following year. Both operating systems were important releases that brought new features to the Mac, such as AirDrop, App Store, FaceTime, and emoji integration.
Although users with newer MacBooks cannot revert to these older settings. Those who still want to use older MacBooks as a second computer or backup will find the upgrade invaluable. As a general rule, all programs launched with OS X Mavericks are too new to use OS X Lion or Mountain Lion.
OS X Lion works with Intel Core 2 Duo, Core i3, Core i5, Core i7 or Xeon processors; requires at least 2 GB of RAM and 7 GB of storage. OS Mountain Lion will run on mid-2007-2020 iMacs, late 2008, early 2009 or later MacBooks, mid-2007 or later MacBook Pros, late 2008 or later MacBook Airs, and early 2009 or later Mac Minis.
