OS X El Capitan feels like a modest update after last year's Yosemite release. Which brought in a complete redesign of OS X and a much better integration with IOS. If you enjoyed what Yosemite had to offer, you'll appreciate the small adjustments made.
PROS
- Generally faster performance
- Split-screen multitasking
- Transit directions in Maps
- Safari gets pinned tabs and an easy way to mute noisy tabs
- Useful tweaks to other built-in apps, like Mail and Notes
