Problem repeatedly occurred" error in Safari 14.1

Fixed!! Just my luck decided to a clean install and this bug showed up! Apple fixed in a week!

Just as Shazbo19 posted below. Uncheck Auto updates, and the update will show up. Not sure how that makes sense, but issues resolved.

SupaMac's suggestion to use Safari Technology Preview works... and you get to keep your passwords!

After downloading the newest update which came in these days (Version 14.1 (14611.1.21.161.7)) the problem seems to have disappeared.

Same problem for me. Took the Catalina 10.15.7 update and got Safari 14.1. Now it's worthless on my MacBook Pro 16". Time to change Default Browser to Firefox or Chrome until Apple gets around to fixing it (don't hold your breath... seems to be a recurring issue for them)

I had this problem as well. I am using Mojave 10.14.6 (18G9028)

I used this webpage to fix the problem on my system.

I have not seen any side effects.

I downloaded the current version 14.1

I just installed today's release (on Mojave 10.14.6) and it is

Version 14.1 (14611.1.21.161.7)

and seems to be working fine on all the websites I checked that were crashing the previous 14.1 release.

Why the stealth mode on functionality, who knows.

Yup. Use Firefox.

I found my solution... changed the default browser to Firefox. Works great. I've already imported Bookmarks in the past, so same familiar use. Screw Safari.

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.

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.

Installed the new build and websites seem to be working fine now. Glad I held off on restoring from time machine. Apple needs to do better to let people know that they F’d up. The support advisor I talked to about this two days ago didn’t have a clue even though the broken safari build had been dropped from the security update.

Try opening System Preferences » Software Update, and then clicking the "Advanced…" button. If that doesn't help, then install Howard Oakley's amazingly helpful "SilentKnight" and "SystHist" utilities, and use them to determine what system updates have already been installed (SystHist), and what newer updates have been released but not yet installed (SilentKnight).

Note also that you may find it worthwhile to disable automatic installation of macOS security updates, assuming you're diligent about checking for the release of new ones.

It does indeed have something to do with Java script security validation. Turning this off prevents the issue, but this is a terrible workaround since nearly all web pages use it (including this one... I had to turn it back on to reply now).

The best solution is to stop using Safari, sadly.

Do you keep backups... restore your data.

djogon, My reply was in no way rubbing in the fact that you still have an problem without a solution. Just that Apple is aware of the issue as they have pulled the faulty Safari update, and that it will be rectified soon. I do however have a potential solution for future use. As I have discovered, through much dismay in the last 5 years, Apple is not reliable in their public releases as much as they used to be. I would suggest that people shut off automatic updates and wait a minimum of two days before they update anything. This has aided me in the past, and just helped me again with this lame Safari release... soon to be re-released.
