There are certainly 21st century settings of Macbeth--that is, performances of the play which are set in the present day. The film made in Australia in 2006, directed by Geoffrey Wright and starring Sam Worthington is certainly an example. In that example, Macbeth is a crime lord.
If on the other hand, you are talking about Shakespeare's language, you have a problem. The problem is that there is no such language as "21st century" and Shakespeare's language is as much English as what you and I are communicating in right now. The reason people have trouble understanding Shakespeare is not that his language is old, but that he is writing in poetry, and complex and difficult poetry at that. For example:
Tomorrow, and tomorrow, and tomorrow creeps in this petty pace from day to day to the last syllable of recorded time. And all our yesterdays have lighted fools the way to dusty death. Out, out, brief candle! life's but a walking shadow, a poor player who struts and frets his hour upon the stage and then is heard no more. It is a tale told by an idiot, full of sound and fury, signifying nothing.
Every single word in that passage, except possibly "player" for which we might substitute "actor", is modern 21st century English. How would you "translate" that into the language in which it is already written? How about this one:
I have given suck and know how tender it is to love the babe that milks me. I would, while it was smiling in my face, have plucked my nipple from its boneless gums and dashed the brains out had I so sworn as you have done to this.
Where are the non-21st century words in that? Maybe we'd say "baby" instead of "babe". Otherwise, sorry, there's nothing to translate.
Possibly what you are looking for is a paraphrase of Shakespeare's poetry that leaves out the complexity and the powerful poetic wording and replaces it with banal and trite lines. Such things do exist. But although you might summarize Macbeth's "Tomorrow and tomorrow and tomorrow" speech as "Life's f___ed up", what you end up with is no longer Shakespeare's play or Shakespeare's characters. It's another play with the same sort of plot.
