The latest update of the apple operating system has come with many new features. Each and every one of them makes the system management and the user experience is exquisite.
With OS X Mavericks We are going to be able to get more out of all the screens that we have connected to our Mac to be able to work as we want, and now there is no longer a main screen and a secondary screen.
In the very renewed OSX Mavericks, now each screen has its own menu bar and the Dock appears in the one you are using at all times, so we can say that finally those from Cupertino have stopped to improve support for external screens by doing make everything much easier when using a second or third monitor.
In previous versions of OS X the Dock was only accessible from the main screen, making it somewhat uncomfortable to have to move the cursor to the main screen every time you wanted to use it.
Now, in Mavericks, when we connect a second monitor, just move the cursor to the bottom of the screen so that the dock goes from the main screen to the secondary screen automatically. Also, you can move it to the sides of the secondary screen.
As you can see, little by little we are informing you of the features that the new OSX Mavericks has. We encourage you to try them and keep reading us.
