And it's been like that for 10 minutes. I clicked the "x" next to the progress bar and when I click the "Download Update" button again it just goes back to "Less than a minute remaining".
Fixed, I didn’t realize that after the download finishes and you see the update thing again, don’t click it, instead look at the top right you will see a little notification that is prompting you to restart, hit that and the update will start

It was a very slow download. It also become stuck for quite a while at the end of the download for me, but I just let it be and eventually the Mac restarted and it updated.
