Last Saturday, Apple has released their new operating system, the Mac OS X Leopard. (I managed to captured this before it launched haha) It has 300+ new features and it is the most impressive Mac OS X version yet. The highlighted features will be the Time Machine and the desktop Stacks. The Time Machine is the breakthrough automatic backup that’s built right into Mac OS X. It keeps an up-to-date copy of everything on your Mac such as digital photos, music, movies, TV shows, and documents. Now, if you ever have the need, you can easily go back in time to recover anything. Secondly will be the Stacks feature, it organize files in a neat stack on the Dock. One click and the stack springs open, revealing items in an elegant arc or an at-a-glance grid. Videos after the jump.
