I am trying to use internet recovery to install OS X Yosemite and dual boot it with High Sierra on my 2015 model 13-inch Macbook Pro, but I’m having some issues. I can boot into Internet Recovery, can choose an internet connection, but after doing that, absolutely nothing happens. The earth icon is still spinning, I can change to a different wifi, NOTHING happens. Is there anything I can do to start Internet Recovery properly? By the way, the computer already has High Sierra installed, and works properly.
