Validate Your Success: After installation, double-check that the PostgreSQL service is running smoothly.

Seamless PostgreSQL Setup for macOS

MacOS users can efficiently install PostgreSQL using Homebrew or the user-friendly Postgres.app. Both provide streamlined processes suited to your preference.

Quick Homebrew Installation
