So you know what a computer is, right? Well, the people who make computers also make different kinds of computers.
One of these is called a laptop, which is a computer that you can take with you wherever you go. And one kind of laptop made by a company called Apple is called a MacBook.
Now, Apple made a new MacBook that is a little different from the old ones. This new MacBook has a screen that is 12 inches big. That's not as big as some other laptops, but it's still pretty big for a laptop.
The new MacBook is also thinner and lighter than the old ones, so it's easier to take with you. Some people really like that.
Oh, and it comes in different colors, too, like gold and rose gold. So it's not just boring like some other laptops.
But one thing that might not be good for some people is that the new MacBook doesn't have as many ports (that's where you plug things into the computer) as the old ones. That means you might not be able to plug in everything you need to, unless you get some special extra cables.
Overall, the 12-inch MacBook is a new kind of laptop made by Apple that's thinner, lighter, and comes in cool colors, but might not have as many plug-in spots as other laptops.
