Problem repeatedly occurred" error in Safari 14.1

I have the same exact issue. I did the update that was available for Catalina and my Safari was updated to 14.1 as part of that.

It is now unusable. We should not have to reinstall the operating system. This was an apple update. My computer was running perfectly before update. I am seeing many people with the same issue. Hopefully there will be a fix.

I agree with you 100% - this is insane. My computer was working perfectly until I did this update. The answer from Apple is to Reinstall the operating system. I am on Catalina and I found out from a friend that even if you upgrade to Big Sur the problem is not corrected. I tried all suggestions.

Same problem for me. Catalina 10.15.7. Safari 14.1. ebay, att.com, mlb.com, cnn, probably many others. Ironically, the MacRumours site is affected as well. Using Chrome until they fix this. Ugh. I was forced to do the update when I got my new iPhone 12 Pro this week.

Out of sheer obstinacy I spent an hour or so yesterday seeing if I could find out from Apple support whether anyone could estimate the time it will take to release a patch, to help decide what workarounds to adopt. After slowly elevating up through several levels I did reach someone who acknowledged this was now a known problem, and that there are valid reasons (i.e. mission-critical 32-bit legacy applications) that some users do not wish to upgrade to Big Sur, which was the solution offered repeatedly along the way. But no answer as to if and when to expect a fix.

I tried to go to

Global.adsbexhange.com

and

adsbexhange.com

Safari, Chrome and Firefox all cannot load, server os not responding. Checked on www.isitdownrightnow.com and the site is DOWN.

I think your problem is not related to the browsers.

Yes, I am.The problem is a specific part of the site global.adsbexchange, the site itself is accessible. But when I want to go to the radar picture, the screen starts flashing and a message appears that something went wrong. It is the same in Firefox (88.0) but only on the iMac. In Safari on my iPhone and iPad everything goes smoothly, no problem (ios 14.5 and iPadOS 14.5).

The problem on my iMac (Catalina 10.15.7) started after upgrading Safari to 14.1, before updating there was no problem. It is strange that Firefox has the same problem.

A new Safari Software Update release has shown up today for my Cat MBP after the original 14.1 was pulled on 4/30. I never installed the original 14.1 release, so I can confirm that it disappeared from Software Update from 4/30 - 5/4. Can someone please confirm that it is now working as intended? AND can someone please post the original 14.1 BUILD number? and if someone has today's 14.1 BUILD number, please post? Why they didn't change the version number is... well... Apple nowadays. Here is what I am seeing in my Software Update now, 5/4 (I did not take a screen shot of the original release):

Please read my earlier posts. If I am too specific I violate the restrictions of Apple. My problem with one site occurs in Safari and Firefox only on Catalina 10.15.7. On opening the site the site opens and closes and gives an error, then I have to restart the browser.

No problems with the site on BigSur 11.3.1 in Safari and Firefox, no problems on iPhone iOS 14.5.1 and iPadOS 14.5.1

At first I thought the problems was caused by the Safari update, but the Security Update seems more probable now.

Just adding to this post and waiting for Apple to provide a Fix. My problem started last week when I wiped my HD and did a clean install of Catalina. Reinstalling the OS will not work unless you opt. security update. Using Chrome as the workaround until a Fix. Was ****** when I spent the time to do a clean install to make and this started and if the only way to fix was to reinstall again, I hope it's not the case!

Same problem: Mac Mini with Mojave 10.14.6. After updating Safari to 14.1 along with a security update at least half of the usual websites I use regularly now "crash" (reload), on some of them part of the content just disappears - and reapperars after I mouse-over to a specific point.

Chiming in to confirm that the updated version of Safari 14.1 does work with websites like Ebay and those bank sites that I use that had not worked on the original version of 14.1. This on two Macs running Mojave.

@Don Mactavish

I was able to refactor some web components with high performance requests. This leads to solving the issue. Seems like Safari was having trouble with the performance.

So end of the story is: Not having this issue any more.

That's not a solution. Apple has to correct it. Safari 14.0.3 works just fine.

Thanks SupaMac... Safari Technology Preview works fine.

I just tried this site on my iPad and it worked just fine. But not with Safari 14.1 on my iMac (macOS Catalina 10.15.7). So the problem is related to Safari 14.1 for Mac.
