You know you could say what the download was so as to keep others from potentially having the same issue. Just saying..Followed a download indicated in blue from the article on Safari problems.
Resulted in Apple Support & re-installation of OS.
No further comment.
I never download anything, not from Apple - but I just did - IDIOT!!
Can't speak to what went wrong with your installation/update but it looks like the link is legit.
On reflection - M1 Mac Mini - told you it was my error. But as I say if I can anyone can.
True! Mega mind glitch.Not sure what else you expect MR to do here. The link was enclosed in a section called "Page Loading Issue on macOS Catalina".
