MAMP is not working. I ask for advice, what is wrong?

Question

MAMP

Good afternoon. I'm looking for a method to install WordPress, so far I've stopped on this program, some difficulties have arisen.
1. Installed MAMP (from the site, free version), but he does not see Apache. What could be the problem?
2. Installed the same MAMP, only version 3.1. Everything is great, just not compatible with WordPress. Is it possible to integrate the new PHP into it?
3. Where can I download the full cracked version of the program (Mac os) (excluding torrent)?
Thanks..

Answer 1

1. Well, guessing on coffee grounds is not here.
2. Isn't it easier to install php, nginx, mysql through the terminal and run projects?
3. Somewhere it is possible, but isn't it easier to use a completely free analogue of https://www.apachefriends.org/en/index.html
