We're doing an IT refresh at work and have some old mid-2011 iMacs in a classroom. I thought I'd just try wiping one using internet recovery to see what happened (it failed), but thought the estimated download time was pretty hilarious. It did jump down from 53 minutes to 31 before it decided to give up 🤣
I reset my brother’s 2011 MacBook a couple years back and had the same thing happen. The progress bar would get entirely full and the estimated time would be either negative 400 seconds or over a billion hours remaining. It would just sit there with weird estimation times for hours. Had to attempt that reset a few times before it actually completed.
