OS X Mavericks (version 10.9) is the tenth major release of OS X (now named macOS), 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 upgrade through the Mac App Store worldwide.
The update emphasized battery life, Finder improvements, other improvements for power users, and continued iCloud integration, as well as bringing more of Apple's iOS apps to OS X. Mavericks, which was named after the surfing location in Northern California, was the first in the series of OS X releases named for places in Apple's home state; earlier releases used the names of big cats.
Apple announced OS X Mavericks on June 10, 2013, during the company's Apple Worldwide Developers Conference (WWDC) keynote (which also introduced iOS 7, a revised MacBook Air, the sixth-generation AirPort Extreme, the fifth-generation AirPort Time Capsule, and a redesigned Mac Pro). 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 can run on any Mac that can run 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 and later versions are all available for free.
The full list of compatible models:
The menu bar and the Dock are available on each display. Additionally, AirPlay compatible displays such as the 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.
OS X Mavericks introduced App Nap, which sleeps apps that are not currently visible. Any app running on Mavericks can be eligible for this feature by default.
Apple now supports OpenGL 4.1 Core Profile and OpenCL 1.2. Server Message Block version 2 (SMB2) is now the default protocol for sharing files instead of AFP. This is to increase performance and cross-platform compatibility.
iCloud Keychain stores a user's usernames, passwords and Wi-Fi passwords to allow the user to fill this information into forms when needed.
The system has native LinkedIn sharing integration.
IPoTB (Internet Protocol over Thunderbolt Bridge) Thunderbolt networking is supported in Mavericks. This feature allows the user to quickly transfer a large amount of data between two Macs.
Notification Center allows the user to reply to notifications instantly, allow websites to send notifications, and the user returns to a Mac in a sleep state, the user will see a summary of missed notifications. Some system alerts, such as low battery, removal of drives without ejecting, and a failed Time Machine backup have been moved to Notification Center.
The "traffic light" close, minimize, and maximize window buttons have appeared somewhat brighter.
The new iBooks application allows the user to read books purchased through the iBooks Store. The app also allows the user to purchase new content from the iBooks Store, and a night mode to make it easier to read in dark environments.
The Open Transport API has been removed. USB syncing of calendar, contacts and other information to iOS devices has been removed, instead requiring the use of iCloud. QuickTime 10 no longer supports many older video codecs and converts them to the ProRes format when opened. Older video codecs cannot be viewed in Quick Look. Apple also removed the ability to sync mobile iCloud Notes if users upgraded their phone OS from iOS 9 to iOS 10, effectively forcing all Mavericks users to update or upgrade their computers.

OS X Mavericks has received a mixture of positive and negative reviews on the Mac App Store.
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.
