There are several ways to install PostgreSQL on macOS, one of which is to use the Homebrew package manager. The following are the steps to install PostgreSQL through Homebrew:

1.If you have not installed Homebrew yet, please run the following command in the terminal to install Homebrew:

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2.Update the local database of Homebrew:

brew update

3.Install PostgreSQL using Homebrew:

brew install postgresql

4.Start PostgreSQL service:

brew services start postgresql

5.Create a new PostgreSQL user and database:

createuser --superuser myuser
createdb mydatabase

6.Login to PostgreSQL:

psql -U myuser -d mydatabase

Congratulations, you have successfully installed PostgreSQL on your Mac!

If you are too fond of tedious operations and command-line installation, then I recommend another way, servbay, which is a graphical way to install PostgreSQL and is also very convenient for one click deployment.
