• Terminal: A method for power users and developers who want fine control or need open-source tools.

How to Install Software from the Mac App Store

The Mac App Store is the safest and easiest method for installing software on a Mac. All apps in the store are verified by Apple to ensure they meet security and quality standards.

Steps to Install Software from the Mac App Store:

Installing Software from Third-Party Websites

Some apps, like Google Chrome, Zoom, or Microsoft Office, are not available in the Mac App Store. To install these, you’ll need to download them directly from trusted third-party websites.

Steps to Install Software from a Third-Party Website:

1. Find the Developer’s Official Website: Always download software from the official developer’s website. For example, to download Google Chrome, visit google.com/chrome.
2. Download the Installer (DMG or PKG): After finding the software, click the Download button. Most Mac software comes as a DMG (Disk Image) or PKG (Package) file.
3. Open the Installer: Double-click the DMG file from your Downloads folder. You’ll usually see an app icon and an Applications folder.
4. Drag the App to the Applications Folder: To install, simply drag the app into the Applications folder.

Installing Software Using Terminal Commands

For advanced users, installing software using the Terminal can be faster and more efficient, especially for open-source software or command-line tools. The most popular way to manage software via the Terminal on macOS is by using Homebrew, a package manager for macOS.

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

   For example, to install wget, you would type:
   
   brew install wget

   1	brew install wget

3. Manage Software with Homebrew:
   
   brew update brew upgrade
