How-To: Make your Mac run silent, cool and fast under OS X El Capitan

As expected, Apple’s release of OS X El Capitan for Macs was less about adding major new features than “refining the experience and improving performance” from Yosemite — in other words, under-the-hood optimizations to make any Mac run more reliably than before. Thanks to El Capitan, my older (mid-2011) 27″ iMac is running better than it has in years: fast, quiet, and cool enough that it might as well be fanless. Rarely does the volume level in my office climb above a whisper, an experience I’ve come to love so much that I’d never want to return to a loud computer.
