Sometimes one display isn't enough. Maybe you want to watch some Netflix while working on an email or doing research file writing a paper. Things can get pretty crowded, with windows squeezed into little corners or tabs that need constant switching back and forth.
Apple's new OS now supports multiple displays, allowing users to get even more stuff done on their Macs. Users can open apps in full screen mode on their second monitor without affecting the main screen or work side by side with multiple windows. Plus, those with Apple TV can connect their computer via AirPlay and turn their television in to a full-powered display.
