Working from home? Add a second display to your Mac setup

If you worked at an office job before the novel coronavirus pandemic, there’s a good chance you’re now working from home. It can feel limiting, especially if you only have a MacBook.Fortunately, you can drastically improve your productivity by hooking up an external monitor to your workstation, usually by using one display as a reference and doing your actual work in the other. (Less wholesomely, you could work in one and watch a movie in another—but I didn’t say that.)
