Apple has released Mavericks. The latest OS X operating system for Mac computers could now be downloaded without cost from the Mac App Store. The OS X 10.9 Mavericks, as it is officially called, featured updates on the iBooks and Maps applications. The Calendar app was also redesigned. Apple's web browser, Safari, also got updated in Mavericks.

The update also introduced the "iCloud Keychain," which would allow users to sync their computers across devices. In addition, the "iCloud Keychain" enabled users to make more secure passwords and give them the opportunity to save their credit card details.

In August, Apple Insider reported that the company was able to sell 3.8 million Macs for the third quarter of 2013. This was lower by 200,000 compared to the 4 million Macs sold in the same period last year. In the September quarter of last year, however, Apple sold even more computers when it posted sales of 4.9 million Macs.
