In this article, we will delve into the world of macOS reinstalling and explore the potential risks and consequences of deleting files during the process.
What Happens When You Reinstall macOS?
When you reinstall macOS, your computer’s operating system is completely wiped clean, including all installed software, settings, and data. This process is called a "clean installation" or "reinstallation." The goal of this process is to start fresh and provide a clean slate for you to set up your computer as you see fit.

During the reinstall process, several files are deleted to ensure a clean start. These files include:
- System files: These are essential files that are required by macOS to function properly. They include system libraries, kernel extensions, and other critical components.

- Software installation files: These are the files that you installed during the reinstall process, including any software that you have purchased or downloaded.
