Apple launched its new MacBook Pro laptop with Touch Bar, the biggest change to the design is the touch bar, new OLED touch panel above the standard keyboard. A small touchscreen, which changes depending on the app being used.

It's a retina display, multitouch, responding to gestures and taps. We call it Touch Bar. First, it replaces the standard system functions, but it goes way beyond that. It adapts to whatever software you're using." says, Phil Schiller, senior vice president of worldwide marketing for Apple.

My main criticism so far is that since the Touch Bar is so small, it can be hard to see which tab is which on the Touch Bar. It would be easier to differentiate between tabs if the Touch Bar showed the logo for the website instead of a miniature version of the page, as per Fortune.

And here are the most useful features worth considering:

Touch ID

The same as that featured on iPhones, has been integrated directly into the power button on the new Macbook Pro. As well as being a secure method to login to the MacBook Pro, it also offers a secure, not to mention fast, way to buy goods online, which might help fight fraud. You can also register the fingerprints of different (hopefully trusted) users. Touching ID will then let you quickly switch between profiles sharing the same machine, reported by IB Times.

Emojis

There can also be a full emoji bar on Touch Bar, much easier to reply and send reactions to messages without leaving the keyboard.

FaceTime

When you receive an incoming call via FaceTime or through your computer, the Touch Bar will automatically transform into a place where you can accept, decline, or send a message, much like in iOS. PayFor the first time, Apple is putting Touch ID on the Mac, and with it, you can make purchases via Apple Pay right on the web.

Function Keys

Even though Apple replaced the function row with an OLED display, that doesn't mean that you still can't access the function keys when you need them. All you need to do is hit the Function (FN) at the bottom and boom, there's your F1 through F12 keys.

Edit Photos and Videos

Photoshop gets sliders for brushes and other tools. More importantly, Touch Bar tools allow you to edit photos in fullscreen mode without having to clutter up the image with your modules. You'll be able to scroll through your photo library with your finger, select a photo, rotate images, crop an image, add a filter, mark images as a favorite and move through a video.

DJ Pro

DJ Pro fans will also be overjoyed to know the Touch Bar will also be compatible with this app, allowing you to mix songs and access features with your fingers. Compatibility will arrive end of this year.
