The new MacBook Pro has one feature that is not like all the users — if you open the lid and connect the power, it automatically switches on. Honestly, it’s hard to think of cases when you need to use a powered off MacBook Pro with the lid open (except to wipe the keyboard), but users are actively searching the Internet for ways to get rid of this.
How to disable automatic download when you open the lid of the MacBook Pro:
Step 1: Go to the applications folder in Finder, then find the Utilities folder and open the Terminal application (or, alternatively, open search and type “terminal” in the command line).
Step 2: In Terminal, run the following command:
sudo nvram AutoBoot=%00
This will help to undo the continued inclusion of the laptop with the lid open when you connect the charging. This setting will remain until you reset NVRAM. To return all to its original state, simply repeat the same steps and add the following code:
sudo nvram AutoBoot=%03
In both cases you will be asked to enter the administrator password. Commands do not work on the 12-inch MacBook and an older Mac.
The new MacBook Pro lost some physical function keys, which replaced the bar Touch Bar, the backlight of the Apple logo and a full-sized USB ports. As it turned out, they also differ from all previous models of absolute silence when turned on. The new MacBook Pro also does not emit any sound, except when the system detects an error.

How to enable sound welcome to a new MacBook Pro
To activate a sound when you turn on the laptop is very simple. To do this, simply enter the command in the Terminal:

I hope that this information will help you.
