How to Come Out of the Clamshell Mode

That is pretty simple to do. All you have to do is lift the display lid of your MacBook. So, the display will now stop on the external display and show up on the MacBook.

Keep in mind that even if you close the lid of your MacBook, it is still running. With the display closed on the keyboard, it may cause overheat depending upon what application you are using and how much memory is being spent.

Make sure that you have placed the MacBook in a proper place so that heat ventilation is happening properly. You may also see the fan of the MacBook spin faster while the lid is closed. When you keep its display lid open, the fan speed is comparatively lesser.
