I just wiped the hard drive on a 2010 mac pro using the recovery mode partition, but now when I try to reinstall (Sierra) I discover that it can't connect to apple because it has to go through the corporate proxy (because reinstalling the OS is obviously something that no-one in a corporate network would ever do…?).
I tried using
networksetup in a terminal, but it doesn't seem to have it: I just get
-bash networksetup: command not found
when I try it.
I tried using a hotspot on my phone, but it still didn't connect so plan C is ruled out too.
What are my other options (Apart from doing the sensible thing and installing Linux)?
