Apple’s released its latest version of OS X for free for users of Mountain Lion, Lion or Snow Leopard, and it’s available right now.
It’s a pretty hefty download, weighing in at 5.9GB, and it’s quite likely that Apple’s servers will go into utter meltdown today; it’s also announced iWork and iLife updates available today.
Hit the link here to get Mavericks now… but be prepared to wait.
