OS X Yosemite

OS X Yosemite (version 10.10) is the upcoming eleventh major release of OS X, Apple Inc.'s desktop andserver operating system for Macintosh computers. OS X Yosemite was announced and released to developers on June 2, 2014, at WWDC 2014and it was released to public beta testers (the first one million people to sign up for the public beta) on July 24, 2014. Yosemite is scheduled for final release to consumers in late 2014. Following the new landmark-based naming scheme introduced with OS X Mavericks.

Design

Yosemite introduced a major revision to the operating system's user interface, designed with inspiration from iOS 7, while still maintaining the OS X look and feel. The interface incorporates a flatter visual appearance with blurred translucency effects.
Other notable design changes include new icons, light and dark color schemes, and the replacement of Lucida Grande withHelvetica Neue as the default system font.The dock is now a 2D translucent rectangle instead of a skeuomorphic glass shelf, reminiscent of the dock design used in early versions of OS X.

Continuity

Many of Yosemite's new features focus on the theme of "continuity", increasing its integration with other Apple services and platforms such as iOS and iCloud. The Handoff functionality allows the operating system to integrate with iOS 8 devices overBluetooth LE and Wi-Fi; users can place and answer phone calls to and from an iPhone using their Mac as a speakerphone, send and receive text messages, activate personal hotspots, or load items being worked on in a mobile app (such as Maildrafts or Numbers spreadsheets) directly into their desktop equivalent.

Notification Center

Notification Center features a new "Today" view, similar to that in iOS. The Today view can display information and updates from various sources, along with widgets. The widgets in the Today view are similar to those of iOS 8.

System requirements

All Macintosh products capable of running OS X Mavericks are supported by Yosemite; as with Mavericks, 2 GB of RAM, 8 GB of available storage, and OS X 10.6.8 (Snow Leopard) or later are required. However, in order to take full advantage of the features in Continuity, a Mac with Bluetooth LE (Bluetooth 4.0) is needed.
These are the models compatible with OS X Yosemite:
  • iMac (Mid 2007 or later)
  • MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
  • MacBook Pro (13-inch, Mid-2009 or later), (15-inch, Mid/Late 2007 or later), (17-inch, Late 2007 or later)

  • Mac Mini (Early 2009 or later)
  • Mac Pro (Early 2008 or later)
  • Xserve (Early 2009)
These are the models that have Bluetooth LE support, and that therefore support Continuity:
  • iMac (Late 2012 or later)
  • MacBook Pro (Mid 2012 or later)
