OS X El Capitan review: bringing even older Macs up to speed

Latest version of Apple's laptop and desktop operating system gains an injection of speed, a new font and a raft of useful small tweaks

The latest version of Apple's laptop and desktop operating system OS X 10.11 El Capitan will genuinely speed up your computer, particularly if you've got an older Mac.

As with Apple's other recent Apple software updates, El Capitan is very much a blink-and-you-miss-it update. Visually it's almost identical to the current OS X Yosemite and you will be hard-pressed to see what's changed other than the new San Francisco typeface from iOS 9.
