Safari 15.0 Update Issue, macOS Catalina

"Website was reloaded because of a problem"

"A problem repeatedly occurred with (site)"


After the Safari 15.0 update on macOS Catalina 10.15.7 I'm getting the above errors on dozens of sites. The website will attempt to load several times with the "Website was reloaded" message at the top, then finally divert to a blank screen with the "A problem occurred" message in the center. The button option below is "Reload Webpage" and then the cycle repeats itself.


Computer has been restarted, Safari has been restarted, history/cache has been cleared, etc.


Is there something I can do to get this to stop so that I can actually use Safari again?

Thanks for that, bryanr14


Before reading this thread I had re-installed Catalina and still had the reload problem with Safari 15.


After reading your reply, I've never heard of swcdn.apple.com so I did some checking. It seems to be a legitimate server for Apple but I still have one question.


Why is Apple providing a fix with this stand alone installer rather than including it in the Catalina re-install? And why aren't they making this known to us?


How did you find out about this link?


I guess I'm just trying to be careful...and a little curious


Thanks again
