How to Install Software on macOS:
Installing any software on your Mac is a simple process. First, visit the official website or a trusted source to download the setup file (usually a DMG or PKG file). Once the download is complete, double-click the file to open it. Drag the application icon into your Applications folder and wait for the installation to finish. After that, you can launch the program directly from Launchpad or the Applications folder. If prompted, allow permissions for installation, and you’re ready to start using your new software.
