M-x in Evil mode

[wiehen]

Hi.

I am new to emacs, so my doubt may be really basic. But I could not solve it 
with research.

How am I supposed to execute commands (M-x), when working in Evil mode, as Vim 
uses <ESC> already?

I am on MacOS, executing Emacs in the terminal. When I use Emacs without Evil 
mode, <ESC> works for M-x. 

I also have problems getting Emacs help in Evil mode 

Thank you.
