If you do have an operating system on your mac and it is functioning then you can download


El Capitan using this method.




How to get old versions of macOS – Apple Support




Go to Download OS and click on OS X El Capitan 10.11


this downloads InstallMacOSX.dmg to your Downloads folder.




The next section can only be done on a mac that is capable of running El Capitan,


a mac that came preinstalled with an OS later than El Capitan will refuse to do the next bit.




When downloaded open to InstallMacOSX.pkg, double-click on


that and an installation window will open, this does not install El Capitan


but converts the InstallMacOSX.pkg to the Install OS X El Capitan.app which 


you will find in your Applications folder, it should be 6.2GBs in size.




(If the installation window asks which disk you want to install to, you must pick 


the disk that you are booted to at the time. Not any internal or external disk that 


you want to eventually install El Capitan on, that is for later.)




To start the installation of El Capitan double click on the Install OS X El Capitan.app.




The copy of the install app self deletes after installing El Capitan, so make sure you keep a copy of the 


InstallMacOSX.dmg if you need it in future, or you could just make a copy of the Install OS X El Capitan.app 


prior to installing and moving it to an external drive for safe keeping. 


It is also possible to create a bootable USB installer disk using the Install OS X El Capitan.app in the Applications folder and the createinstallmedia 


command in the Terminal app.
