Apple announced El Capitan the latest version of it’s OS X operating system, 10.11, on the 9th September 2015, at the Bill Graham Civic Auditorium in San Francisco, California in the United States. A very important question at this moment is Should you upgrade to EI Capitan? As per me i would say yes, you should. But won’t recommend to rush for it. Before you rush to new upgradation, back up your Mac first, because your Mac is well within supported model range and should handle EI Capitan quite well.
