Mac OS X Lion 10.7 launch date has been set to July 20th 2011.

Apple has priced Mac OS X in such a way that most users will probably upgrade. Also, rather than having to drive to the Apple store to get the latest OS X, you just need to download it from the Mac App Store. You don’t need to drive to a store, bring home a box, and install a bunch of discs. All you do is click the Mac App Store icon, buy Lion for $29.99, and your Mac does the rest. Just make sure you have what you need to get your hands on Lion the minute it’s available.

Some of the highlights of Mac OS X 10.7 Lion include:

  • Multitouch gestures
  • Full screen applications
  • Mission Control
  • Auto Save and Versioning
  • Launchpad
  • Auto Resume of apps
  • Mac App Store — now with in-app purchase
  • AirDrop – P2P Wi-Fi networks
  • Newly designed Apple Mail
  • Better Search

How to upgrade to OS X Lion 10.7 :

Step # 1 : Make sure your Mac can run Lion.

Your Mac must have either Intel Core 2 Duo, Core i3, Core i5, Core i7, or Xeon processor to run Lion. Also, ensure that you have OS X 10.6.8. A few weeks ago, Apple released Mac OS X 10.6.8 to help prepare users for Mac OS X Lion. To find out if your current Mac has one of these processors : Click the Apple icon at the top left of your screen, then chose About This Mac.

If you don’t have OS X 10.6.8 already, to update your system, click on the Apple menu and select “Software Update.” Go ahead and install any of the updates for your system and official Apple applications.

Certain apps and utilities will need to be updated to work with Lion, so it’s important to make sure you are running the latest versions. If you are using an older printer or scanner, you might want to determine if the manufacturer has updated drivers or has a plan for Lion compatibility.

Step # 2 : Check Disk Space

OS X Lion 10.7 will need 4GB of space. Make sure you have that much free space available. If needed, make room for more free space. Probably one of the good reasons to remove some unwanted stuff.

Step # 3 : Check compatability

Apple is officially dropping support for Rosetta. Rosetta was a technology that Apple developed to help users run older PowerPC apps on Intel Macs. Over the last five years, most major Mac apps have been updated or rewritten to work natively as Intel Mac apps or as universal binaries. A handful of older applications (for example : older versions of Adobe Creative Suite and Quicken 2007) will not work with Mac OS X Lion. You’ll have to upgrade to newer versions or find replacement apps.

Step # 4 : Backup your Mac

Do take a backup of your system disk before any such major upgrade. While OS upgrades are more or less error-free now-a-days, there’s nothing worse than realizing later that you should have taken a backup. Preferably use a external hard disk to take a backup.

You use Time Machine to take the backup. Just open up the app in your Applications folder or from its panel in System Preferences. Just plug in a hard drive, and tell Time Machine that you want to use that drive (or a partition on that drive) for your backups.

Step # 5 : Download OS X Lion from the Mac App Store.
