I have a mid-2012 MacBook Pro, with root setup and SIP disabled.
I was downloading files today, and suddenly my computer couldn't connect to the internet (it said that it had a self-assigned ip). No problem, I get an ethernet cord.
Later, my apps start freezing, so I restart my computer. When I log in, I got stuck at the login window, but on top of the login window, messages launches. I shut down my computer, restart in Recovery mode, and re-install macOS Sierra (with ethernet to download it quicker).
As soon as it's done, I try logging into my user account. It loads infinitely. I then try logging into my user account and root through the other users option. Doesn't load.
Is there any way to login? I've never had this problem before, though I periodically have to re-install macOS Sierra.
