Apple has officially announced the new MacBook Pro

Apple announced a new line of MacBook Pro laptops on Thursday.

The biggest new feature on these redesigned computers is a new kind of keyboard with an integrated touchscreen strip that replaces the traditional function keys called Touch Bar.

The new MacBook Pros also have a larger trackpad.

"The Mac is so incredibly important to us," Apple CEO Tim Cook said at a media event held at Apple's Cupertino, California headquarters.

Here's what you need to know:

The new MacBook Pro comes in 13-inch and 15-inch sizes.

Both versions are thinner than Apple's old MacBook Pro. The 15-inch model weighs 4 pounds.

The new touchscreen part of the keyboard is called Magic Bar. It changes and adapts to whatever software the user is using at the time. For example, if you're in Safari, you'll see shortcuts. There's also an emoji keyboard as well.

As you're typing, Touch Bar can also show quick type suggestions, like the iPhone keyboard does.

There is also a TouchID fingerprint reader integrated into the Touch Bar, which enables purchases with your fingerprint, and presumably, will lock your laptop in addition to a password.
