What can you do with the Mac OS X 10.11 El Capitan Installer Disk?

The Mac OS X 10.11 El Capitan Installer Disk will upgrade earlier Mac systems to El Capitan, or allow you to install a new system from scratch. If your Mac can run Mountain Lion (OS X 10.8) and has at least 2 GB of RAM, it should be able to install El Capitan. Installing El Capitan is a prerequisite to safe upgrades to later systems. 2 GB of RAM should be considered a bare minimum, 4 GB is better if you want your Mac to maintain its speed.

When upgrading to El Capitan, the installer will check your present system to make sure it is running at least 10.6 Snow Leopard. The installer will install El Capitan over systems running 10.6, 10.7, 10.8, 10.9 and 10.10, upgrading them and keeping your files, settings and applications (as long as they are compatible versions).

If you are still running 10.5 Leopard on the Mac you are upgrading, then you might be able to use this disk to upgrade – please check this post.
