More than five months after Apple first spread the word about its latest desktop operating system, OS X 10.8 Mountain Lion finally landed Wednesday, and if you’ve got a late-model Mac, you can upgrade for just $19.99.
Following in the footsteps of iOS, Mountain Lion includes Notes, Reminders, Game Center, AirPlay, and Twitter integration, among other new features. It also boasts Gatekeeper, a security feature meant to protect users from malware.
Here’s what you’ll need to have in order to run Mountain Lion:
- iMac (mid-2007 or newer)
- MacBook (late 2008 aluminum, or early 2009 or newer)
- MacBook Pro (mid/late 2007 or newer)
- MacBook Air (late 2008 or newer)
- Mac mini (early 2009 or newer)
- Mac Pro (early 2008 or newer)
- Xserve (early 2009)
