Download El Capitan dmg via PC
My Mac is stuck on Internet recovery after I performed a disk erase. I want to do a clean install of the OS, so I need to get hold of the El Capitan dmg. I only have access to a PC, so I need to log in to the Apple app store from my PC to download the dmg and write it to a USB stick.
How do I sign in to the Apple app store from my PC? How do I get hold of this dmg?
Mac mini, OS X El Capitan (10.11.3)
