How to Download and Perform a Clean Install of El Capitan OS X 10.11
El Capitan OS X 10.11 is the twelfth major release of macOS, Apple's desktop and server operating system for Macintosh computers. It was released on September 30, 2015, and it focuses mainly on performance, stability, and security improvements.
In this article, I will guide you through the steps to download and perform a clean install of El Capitan on your Mac. A clean install means that you erase everything on your current startup drive and install a fresh copy of El Capitan. This can help you fix some problems with your Mac, such as slow performance, compatibility issues, or corrupted files. However, before you proceed, you should back up your important data to an external drive or a cloud service, as a clean install will delete all your personal files and settings.
