Do you have more than one Mac on your desk or at your office? If so, then you should grab Teleport and control them all.
Teleport is a system preference that allows you to control other Macs with the keyboard and mouse that you’re currently using. Just scroll off the edge of your screen and on to the other computer. Then keep using the keyboard and mouse as you normally would and you’ll be working on the other computer.
Better yet, it can synchronize the clipboard between machines and you can drag files back and forth between computers.
Teleport is free, extremely easy to install and setup, and works well. I’ve been using it for months with no issues and it comes in extremely handy.
