New macOS High Sierra emoji
The macOS 10.13.1 update adds over 70 new emoji to your Mac. This arrives in tandem with the iOS 11.1 update on the iPhone and iPad and brings those same emoji to your computer.
If you are a huge fan of emoji, or even if you just get a lot of emoji sent to you, this is a feature worth upgrading for. You will need macOS 10.13.1 to send the new emoji and to see the new emoji.
Sure, Emoji aren't groundbreaking and won't help you get more done, but it's nice to see a lot of emoji arrive all at once.
