So I just contacted Apple Support VIA live chat, I needed help formatting my SSD on my new 2015 13" rMBP as it's getting sent back tomorrow. As I've never formatted a Mac, I had no idea what I was doing, hence why I contacted them. BIG mistake. The assistant was utterly useless, and as a result ruined my Machine. He walked me through the steps whilst I was talking to him on my other Mac, and once I hit the 'Erase' button he asked me to select the 'Restore' button. I told him the options available in that panel... Something like, Disk: Macintosh HD - Destination: (blank) and that the restore button was greyed out. The assistant then went completely unresponsive and for 10 minutes I waited for a response. The chat then ended, and not knowing what to do I exited the the Disk Utility and restarted my MBP. Only to be presented with a black screen and a large icon in the middle of the screen (no access symbol) and could not load my BRAND NEW MBP. I am now in the process of re-installing Yosemite from the recovery utilities on boot up and have no idea if this is going to work. I am extremely pissed off and shall be filing a complaint.
