Craig Federighi spoke to us at this year's WWDC Keynote about the compatibility of the new OS X Mavericks with two or more monitors which the current OS X Mountain Lion does not allow. Personally and unfortunately, I do not have the possibility to test this great compatibility of the new OS X 10.9 with several monitors, but below we will see a video in which up to 6 monitors can be seen connected at the same time (on a Mac Pro) and how Apple's new operating system works perfectly on them.
You can see some of the improvements implemented in the first beta of OS X Mavericks by simply observing the option to use each screen individually for applications, we also see in the video a menu bar for each of the monitors, but let's better see the video that this user posted on youtube.
The video shows good performance and fluidity with the new multi-display support of OS X Mavericks on this Mac Pro, but its creator also talks about small bugs found that Apple is expected to correct in later versions of the new operating system. You can also see in this DP1 how the small but necessary improvements of Mission Control gives us the possibility of using an application for each monitor individually.
Without a doubt and considering that it is just the first beta of this new OS X 10.9 Mavericks, it is possible that in the final version of the operating system that is expected for autumn some changes and improvements will be made in what many Mac users were waiting What is it the ability to use multiple monitors with OS X.
