Summary : Use a single keyboard and mouse to control multiple computers
Description :
Barrier is software that mimics the functionality of a KVM switch, which
historically would allow you to use a single keyboard and mouse to control
multiple computers. Barrier does this in software, allowing you to tell it
which machine to control by moving your mouse to the edge of the screen,
or by using a key press to switch focus to a different system.
