Apple has announced OS X 10..9 Mavericks - Available today for free!!

Finally has Apple announced the final version of OS X 10.9 Mavericks, with a lot of new cool features. One of them is a new multitasking feature that saves battery life by putting apps that you don’t use at the moment in a kind of sleep mode, so that they don’t use any power anymore. When you then need to use these apps again, they start immediately, so you will not see or feel any difference. It will not slow down your productivity, just give you more battery life.

Push Notifications from websites

Another cool feature is a new way to keep users engaged with your website. You can now use the Apple Push Notifications Service to send notifications to your website users through popup alerts, the notifications will appear in your desktop and in OS X’s Notification Center even when Safari isn’t running. Safari Push Notifications work just like push notifications for apps. They display your website icon and notification text, which users can click to go right to your website. That’s a pretty cool way to get breaking news from your favorite websites.

iCloud Keychain

Another cool feature is the iCloud Keychain, it takes your saved passwords and credit card numbers in OS X, and makes them available on all your iOS devices. Works only with iOS devices as usual though, so if you have an android phone for example (like me), then you are out of luck on this one.

OS X 10.9 is available from today, and it’s totally free. Yeah you heard that completely right, it’s free for existing users.
