After removing Oh My ZSH! problems with the terminal - how to fix it?

Question

Command line

Greetings
I decided to try Oh My ZSH! for the terminal, installed, uninstalled, noticed that now instead of:
Mac-name:~ user$
Here is such a thing:
Mac-name%
And you know, it worries me. It seems that everything works, but I would like to return the invitation to the input of the former earlier.
Why did this happen, are there consequences hidden from me and how can I fix it?

Answer 1

delete zsh configs
rm ~/.zsh(rc|env)
