Apple, today, released the next generation of the Macintosh operating system: OS X 10.11 El Capitan.
2015 is a "rebuilding" year for both iOS 9 and OS X El Capitan with both new operating systems focused on making things run smoother, faster, more efficiently and securely.
With El Capitan, Apple brings Split view to OS X - one of my favorite feathers - new features to Mission Control, the new San Francisco display font, faster graphics with Metal (requires 2012 or later Macs) and many more features and enhancements.
El Capitan runs on most Macs that have been released since 2007 and requires that the Mac has OS X Snow Leopard 10.6.8. El Capitan requires about 6GB of free disk space. As with the last few releases of OS X, OS X 10.11 El Capitan has been released by Apple for free.
