OS X Mavericks (version 10.9) is the tenth major release of OS X, Apple Inc.'s desktop and server operating system for Macintosh computers. OS X Mavericks was announced on June 10, 2013, at WWDC 2013, and was released on October 22, 2013, as a free update through the Mac App Store worldwide.
The update places emphasis on battery life, Finder enhancements, other enhancements for power users, and continued iCloud integration, as well as bringing more of Apple's iOS apps to the OS X platform. Mavericks marks the beginning of a change in the naming scheme of OS X, departing from the use of big cats and moving to names based on places in California; OS X Mavericks is named after the surfing location in California.
OS X Mavericks was announced by Apple during the company's 2013 Apple Worldwide Developers Conference (WWDC) keynote, held on June 10, 2013. iOS 7, a revised MacBook Air, the sixth generation AirPort Extreme, the fifth generation AirPort Time Capsule, and a completely redesigned Mac Pro were also announced during the keynote. During a keynote on October 22, 2013, Apple announced that the official release of 10.9 on the Mac App Store would be available immediately, and that unlike previous versions of OS X, 10.9 would be available at no charge to all users running Snow Leopard (10.6.8) or later.
On October 22, 2013, Apple offered free upgrades for life on its operating system and business software.
OS X Mavericks is compatible with most Macs that are capable of running OS X Mountain Lion; as with Mountain Lion, 2 GB of RAM, 8 GB of available storage, and OS X 10.6.8 (Snow Leopard) or later are required. Mavericks is free to upgrade and all later versions are free.
The full list of compatible models:
- iMac (Mid-2007 or later)
- MacBook (13-inch Aluminum, Late 2008), (13-inch Polycarbonate, Early 2009 or later)
- MacBook Pro (13-inch, Mid-2009 or later), (15-inch or 17-inch, Mid/Late 2007 or later)
- MacBook Air (Late 2008 or later)
- Mac Mini (Early 2009 or later)
- Mac Pro (Early 2008 or later)
- Xserve (Early 2009)
New and changed features
The following is a list of features that differ from previous releases of OS X:
- Improved multiple display support: The menu bar and the Dock are available on each display; Apple TV can be used as an external display.
- Mission Control has been updated to organize and switch between Desktop workspaces independently between multiple displays.
- Finder enhancements, including tabs, fullscreen support, and document tags. Pinch-to-zoom and swipe-to-navigate-history gestures have been removed, although both are supported anywhere else.
- New iBooks application.
- New Maps application.
- Calendar enhancements.
- Safari browser enhancements.
- iCloud Keychain sync.
- Notification Center enhancements.
- Some skeuomorphs, such as the leather texture in Calendar, the legal pad theme of Notes, and the book-like appearance of Contacts, have been removed from the UI.
- Timer coalescing, which enhances energy efficiency by reducing CPU usage by up to 72 percent.
- App Nap, which sleeps apps that are not currently visible.
- Compressed Memory, a virtual memory compression system which automatically compresses data from inactive apps when approaching maximum memory capacity.
- Server Message Block version 2 (SMB2) is now the default protocol for sharing files.
- LinkedIn sharing integration.
- OpenGL 4.1 Core Profile.
- OpenCL 1.2.
- USB syncing of calendar, contacts and other information to iOS devices has been removed, instead requiring the use of iCloud.
- Some system alerts, such as low battery and removal of drives without ejecting, have been moved to Notification Center.
- The Open Transport API has been removed.
- Quicktime 10 does not support many older video codecs and converts them to the ProRes format when opened. Older video codecs cannot be viewed in Quick Look.
- Improved Privacy: Safari now supports browsing in private browsing mode with certain windows (as opposed to all the windows having to be either in or out of private browsing).
- The "traffic light" close, minimize, and maximize window buttons have appeared somewhat brighter.

One complaint is that Apple removed the local sync services, which forces users to get iCloud to sync iOS devices with the desktop OS. However, this feature has since returned in the 10.9.3 and iTunes 11.2 updates.
During the first few weeks after OS X Mavericks was introduced, a substantial number of Western Digital external hard drive users complained about data losses (and corruption) when they upgraded to OS X Mavericks, especially when the hard drives were used in conjunction with Western Digital's proprietary disk management software. This forced Western Digital to take down a few of its apps such as WD Drive Manager, WD RAID Manager and WD SmartWare and issue statements urging its users to delay upgrading to OS X Mavericks and to stop using the Western Digital software for the time being. An upgrade for WD Smartware introduced on 25 November 2013 has supposedly resolved the issue.
Versions of OS X Mavericks before 10.9.2 can fail to validate a Secure Sockets Layer or Transport Layer Security certificate's signature in cases where the connection is made with TLS versions 1.1 or below or SSL 3.0 and forward secrecy is enabled. This allows a man-in-the-middle attack to take place under these circumstances. This vulnerability has been assigned the Common Vulnerabilities and Exposures number CVE-2014-1266. OS X version 10.9.2 patches this vulnerability.
