Install of Big Sur stuck on "installing-calculating"
My computer says it is an early 2014 Mac book Air 13". It has OS X El Capitan right now. It took 3 tries to get Big Sur to download. It kept getting stuck at 12.4gb of 12.4gb downloaded. It finally has made it to installing. But has been stuck on "installing-calculating" for about an hour. Is this normal?
