    Hi guys
    I am probably asking something stupid, but I don't know how to do it as I have never done it before.
    Basically I have a middle 2011 macbook pro with el capitan installed, it has been a trusted partner in crime but at this point I would like to install again the operative sistem and format the hard disk. I have never used time machine, so I don't have any saved version. I Have all the data backed up but where do I get el capitan and how I install it?
    Thanks in advance

    With clean installs, I have used the USB method where you backup all files-->download El Cap-->make a bootable USB installer with El Cap-->boot into the USB installer-->erase all contents on the startup disk-->run Disk Utility-->then Install Mac OS X from the USB installer

    This may be of use :)

    El Cap can be downloaded from the Mac App Store - it should be available under a 'Purchased' tab, where you can download it. You will get a message telling you that you already have El Cap installed - just click the message that allows you to download it again
