Big Sur Download Stuck?

[countryside]

Should I be concerned if my MacBook has been sitting at the last leg for 20+ minutes?

I was installing Big Sur on an old iMac 27 retina (2014 late), and I experienced the same problem — white logo on black screen for hours and the progress bar stays at about 90%.

Restarted into safe mode, the Big Sur screen appeared and got me logged in. Yet, the system runs in a slow and buggy way and blacked out to reboot.

I restarted mine too... not into recovery mode (I know, very risky... I have backup). It went to login screen. Seems fine, a little slow.

I don't remember having five of these in Disk Utility.
