Upgrade to OS X Yosemite?
Is upgrading to OS X Yosemite really worth it? OS X Mavericks already has a better bunch of Yosemite-like features that I found. Please tell me!
MacBook Pro (Retina, 13-inch, Late 2013), OS X Mavericks (10.9.5), null
That's a personal preference. Yosemite has a few features that Mavericks doesn't, like SMS messages in the Message app and making calls on the Mac. If you see no new features that you need, then stay with Mavericks if you are happy with it.
Best thing to do is to install it on another drive and see how you like it.
