Solution to fixing "Installation of macOS could not continue." issue
There was an older post that I was unable to reply to to inform others what the solution was, that worked for me and continues to work for me.
When a person gets this issue found down below, which on occur on any iOS. This just happened to me with Big Sur. I copied the image down below from a previous post I was unable to reply to.
Go to Terminal and put in the following
date mmddhhmmyy
mm=month
dd=day
hh=hour
mm=minute
yy=year
Quit out of terminal and try again. It should work now.
The only explanation I can think of, is that it has lost what the date time and year it is.
