Apple is slated to release Mac OS X Lion 10.7 later this month. Mac OS X Lion boosts over 250 new features such as Mission Control, Launchpad, Versions, FaceTime HD, AirDrop, Multi-Touch Gestures, Resume, Auto-Save, Full-Screen Apps etc. At just $29.99 for the upgrade, Mac OS X Lion is a no brainer upgrade for Mac users.
Apple also drops some features out of Mac OS X Lion compared with Mac OS X Snow Leopard. These ‘missing features’ will be kept intact If you’re upgrading from Snow Leopard. If you install Mac OS X Lion from scratch, these tools will be gone.
iSync is the utility that allows you to sync the information on your Mac with Bluetooth devices. For example, iSync plug-in software is used in order to sync calendar and contacts info on your Mac over to your Nokia phone. Apple uses iTunes for its content sync, iSync is meant for supporting third party hardwares and it meant little for Apple to support iSync further.
Front Row is the TV-oriented media center playback app for your photos, music and movies in iTunes. Front Row was released in 2005 together with an IR remote to control its functionality. Apple has stopped bundling IR remote with iMacs and other models, signaling a lack of interest in Front Row.
It is not a surprised that Front Row is dropped from Mac OS X Lion. AppleTV is the device of choice for streaming iTunes content, and Front Row functionality is now the interface for AppleTV.
Rosetta is the piece of system software within Mac OS X that enables software compiled for PowerPC processor to run on Intel Macs. Rosetta is not supported in Mac OS X Lion, thus PowerPC software such as Appleworks, Office 2004, Quicken 2007, Photoshop CS 4 etc will not work under Mac OS X Lion.
Java runtime used to come preinstalled in Mac OS X, but it is no longer the case with Mac OS X Lion. Apple no longer maintains and supports its version of Java runtime for Mac, instead Java for Mac will be part of OpenJDK going forward.
When you attempt to run a Java app, Mac OS X Lion offers to look online for a version it can install.
Similar to Java runtime, Mac OS X used to come preinstalled with Adobe Flash and plugins. Starting with Mac OS X Snow Leopard for MacBook Air, users are advised to download Flash software from Adobe website if required.
Mac OS X Lion will be available only from Mac App Store. There is no retail box that you can buy.
Mac OS X Server
There is no separate Mac OS X Server for Lion. Lion Server will be an add-on to Mac OS X Lion. There will be a $49.99 download of a software bundle of server components directly from the Mac App Store. The pricing is a sharp contrast with $499 for Mac OS X Snow Leopard Server.
Core 2 Duo 64-bit processor required
Mac OS X Lion requires 64-bit CPU, with a minimum Core 2 Duo processor. Any Mac bought within the last 5 years should have the Core 2 Duo CPU minimum. Snow Leopard is able to run under older Core Duo.
There is no official USB 3 driver under Mac OS X Lion. Understandably as there is no Mac with a USB 3 port yet as Thunderbolt is the next-gen device interface for Mac.
