macOS Sierra installation stuck
I’m trying to do a fresh install on a 2013 MacBook Air. I formatted the disk, and started the installation. After it was 2/3 finished the first time, I got an error message saying that the download of macOS failed, and to check my purchase (whatever that means). So I quit the installation and restarted it. Now it’s been stuck on “5minutes remaining” for 4 hours, and the progress bar is completely empty.
