Problem repeatedly occurred" error in Safari 14.1

On Catalina (v10.15.7)…

• the build version of Safari 14.0.3 (before the 14.1 update) was 15610.4.3.1.7
• the build version of Safari 14.1 (buggy update, released Apr 26th) was 15611.1.21.161.5
• the build version of Safari 14.1 (corrected update, released May 4th) is 15611.1.21.161.7

On Mojave, the build numbers for Safari 14.1 are the same as above, except that they begin with 14 rather than 15.

Detailed info about the security content of each of the two Safari 14.1 updates are available at the following links:

• Safari 14.1 (buggy update, released Apr 26th)… <https://support.apple.com/kb/HT212318>
• Safari 14.1 (corrected update, released May 4th)… <https://support.apple.com/kb/HT212340>

Note that the description of the latter says that it "includes the security content of" the former.

More info about this issue is available in the content and comments of the post "Apple has pulled Safari 14.1 update for Mojave and Catalina" at Howard Oakley's wonderful Mac tech blog, The Eclectic Light Company.

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've just installed Safari 14.1 on a MBP running Mojave after the OS suggested the update along with a Security update and have the same problem, Ebay and several other sites constantly failing to load pages and throwing out requests to reload. Your suggestion is to re-install the OS because Apple broke the browser? What is that based on ? It would seem better to just use Chrome or Firefox until Apple figures out what they broke.

This seems to be similar to issues others are having after the Safari 14.1 update 4/27/2021 that was part of the Catalina 10.15.7 update and it relates to JavaScript.  

Test the following:

Turn off “Enable Javascript” in Safari: Preferences: Security 

See if this resolves the the issue loading pages  

This is not a solution since pages are only partially complete and lacks any Javascript functionality.  

I am still searching for a fix.

Bottom Line: At this point this is most likely an Apple bug/issue related to 14.1 and they need to offer a fix other than an OSX reinstall and that reminds me of the #1 Microsoft Windows issue solution!

Backup first.

Reinstall macOS.

Use macOS Recovery to reinstall the Mac operating system.

I have no problem opening eBay after todays update.

UPDATE:

I love the irony that JavaScript needs to be enable to access these forums...

I have been working on this issue and so far the only current workarounds / solutions are:

1) Reinstall the OS BUT I have not tested and is time consuming...

2) Use Firefox ( My preferred solution while I wait for Apple to release a fix/update. )

3) Use Chrome ( I avoid due to security concerns and data harvesting by the big G. )

4) Install the Apple Developer preview of Safari 14.2 ( https://developer.apple.com/safari/technology-preview/ ) NOTE this is a preview that coexists with the current version of Safari ). Since it is not an official release there are risks. I have tested and it works perfectly opening problem sites.

Some research on the net points to an issue with a file named libwebrtc.dylib. With 14.1 it has the date March 1 2021, the version with the 14.2 Preview is March 30 2021... Due to strict OS integrity controls by Apple (SIP) one cannot simply delete the updated version of Safari and reinstall the previous version from a TimeMachine backup. The same is true for other System files like libwebrtc.dylib . I may test a file swap by disabling SIP, swap the file and reenable SIP but that is a risky test and I need time in case a full OS rebuild is needed.

So far Firefox is the simplest solution.

Prost!

I posted this on the other thread as well. https://discussions.apple.com/thread/252711711

I am having a similar issue. This happens after updating Safari to 14.1. There are a few websites that just won't load up. The message that I'd get is "A problem repeatedly occurred with '[html address]' - Reload Page".

I don't want to reinstall OS (I'm on Catalina 10.15.7) just to fix it. I am hoping the next Safari update will fix it.

In the meantime, I downloaded Safari Technology Preview to use (I prefer not to use Chrome). https://developer.apple.com/safari/technology-preview/

So far, I don't have any issue loading any websites using the Safari Technology Preview.

I hope this helps anyone who still prefer to use Safari but doesn't feel like reinstalling the OS just to fix a Safari issue.

Shouldn't it be possible to just reinstall 10.15.7 (or 10.14.6) to revert Safari to its stable state?

Looks overkill to me, to wipe everything... I'll try this tonight for Catalina:

There was an issue with Safari 14.1 in an update the last week of April. Apple released a Safari

"14.1" fix May 4/5. Have you checked for the latest update?

I have details on the issue, test to identify, work around and where to find the latest update here:

https://discussions.apple.com/thread/252710814?answerId=255146246022#255146246022

Read all postings, there is an update after the "Solution".

I hope this helps.

If you are still having issues with the latest GA release version have you tried to install the Apple Developer preview of Safari 14.2 ( https://developer.apple.com/safari/technology-preview/ ) ?

NOTE this is a preview that coexists with the current version of Safari, it is a separate application in the Applications folder .  When I first ran into the Java issues I tested and it worked perfectly opening problem sites. Many of the normal common or shared OSX libraries are completely separate from the current release.

Hope this helps

The plot thickens. Got this dialog box when trying to delete the very email notification of the previous post in this thread. I've never seen a dialog like this from Apple Mail. This sounds like a file system issue.

Looks like Apple has seriously dropped the ball here.

Same issue using Mojave and Safari 14.1. Updated Safari yesterday and had no problems until a couple hours ago. No problem with Firefox or Chrome. Looked in Develop and see a slew of these JSS errors.

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):

Confirming that disabling Java does allow pages that were in a constant reload cycle using Safari 14.1 on Mojave will now load and stay loaded but of course as you say without Java all sorts of essential functionality is lost.

LOL, like the post button on this post. I had to re-enable Java to post this reply.

I have been using Apple for years and never had this type of issue. I know very little about computers and Apple needs to make the fix in their software.....especially for seniors who have no idea what you are talking about.
