I just got a new 1TB SSD that I'm upgrading to and would rather do a fresh install than to clone my current drive over. I already downloaded Sierra to it, but I honestly don't like the flat icons, plus I'm thinking Mavericks will run on my 2011 better than Sierra would. I'm wanting to make a Mavericks Boot Drive so I can install to the SSD, but obviously the installer is no longer offered by Apple. Does anyone know where I can download the installer? I managed to find the ESD, but that isn't doing anything for me. Any help would be appreciated.
