Safari 15 not opening websites - "a problem repeatedly occurred"

To Wheel64:

This is an update to my original post and referencing your problems. Like you I suspected it was not just Safari 15. So.....

I reinstalled my Hard Drive -using the Restore feature - from my Time Machine Back-up of a few days before, i.e. before downloading the Security Patch and Safari 15.0 at the same time on Sept 21. which then caused all these problems.

The re-install took about 3 hrs. but it sorted everything out, and no issues. NOW the good part...

I decided to move step by step to update, to be current.

So I only allowed Apple to download and install the Security Patch, on its own. Once installed I checked everything was OK. And everything worked OK as before, but I am still using Safari 14.1.2

So, then and only then I downloaded and installed, ( as separate instruction) Safari 15.0 and nothing else. This item just took less than 5 mins. and my system didn't need to re-boot.

Again I tested everything and everything worked... no issues.... all websites opening their log-in pages.

My only thought is that installing the Security Patch and Safari 15.0 simultaneously caused the bug on my MacBook pro to prevent accessing -in my case - a whole host of financial institution log-in pages. However by downloading these 2 items separately allowed my system to update with no errors or issues.

I spoke with Apple support today. I had already reinstalled the Safari 15.0 app again, from an apple link.

they advised me to do a reboot into "Safe Mode". it apparently clears out the caches, and other items as part of the boot up.

Intel processor

1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.
2. Release the key when you see the login window, then log in to your Mac. 
3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window.

After doing this, I can receive texts from the bank for 2 factor authentication , and login .

still have no audio when streaming SiriusXM, but that is a minor problem. ( we tried resetting the Nvram, but it didn't help)

You might want to try if you are having trouble with safari.

I have had the same problem ( but only for Financial Institutions websites, including insurance co.s - one outlier -Xfinity and AT&T) Originally like you I thought it was Safari 15.0 which I downloaded on 9/21/21. So I reinstalled Safari 14.1.2 from Time Machine Back-up and the same problem continued.

It's not Safari...it's the Security Update to MacOS Catalina 10.15.7 which I believe is causing the problem.

So I re-installed ( Restored) my previous MacOS operating system /Hard Drive ( not just HD Mackintosh - Data) but everything as at 9/19/21 - i.e previous to the updates. And now everything for me at least works perfectly. No issues

Someone else suggested upgrading to Big Sur but I was not that keen, so effectively I have down graded to 10.15.7 before the Security Update/Safari 15

To Repeat, I don't believe the bug is in Safari.... it's in the Security Update posted at the same time.

But am no expert on this. All I know is that by reinstalling a previous version of MacOS from my Time Machine Back up I solved my problem

Good day.

My father had a similar issue with his older Macbook and asked me for help.

A reinstall of macOS temporarily fixed his problem, until automatic updates brought the issue back.

Reinstalling Safari (the installer package for Catalina) did not fix anything.

In the end, the fix came down to the following:

In the Safari Menu Bar, go to Develop >> Experimental Features >> then check both WebGL 2.0 and WebGL via Metal.

If Develop is not in the Safari Menu bar, go to Safari >> Preferences >> Advanced >> and tick "Show Develop menu in menu bar" down the bottom.

I hope this helps out most of the folks in this thread. Have a nice day!

The problem seems to begin after attempting to login - the redirect confuses the browser. Does anyone know what's going on Switching to Opera and Brave until this gets fixed. See screenshot for typical error page below....."

-------

What to Do:

Boot into Safe Mode [Hold Down: shift key upon boot] and then perform the following:

A. Remove: Login Items:

See if Safari and/or Chrome are Login Items. If so, remove them as such and then restart the Mac, seeing if it/they no longer load(s) at login.  Go Here: Change Users & Groups Login Items preferences on Mac - Apple Support.

B. Uninstall: Security Software:

Any Security Software installed on your computer? If so, uninstall it. Use the Uninstaller for to do so, getting the Uninstaller directly from my Developer’s site, as getting it else where may result in Malware or Spyware being installed. If you are uncertain which to download, then as the Developer. What is it doing is running you through VPN (Virtual Private Network), and your location is seen elsewhere — perhaps a location that this site is inaccessible to.

C. Scan: your Mac for Malware: 

Use MalwareBytes for Mac --- This is software that searches for malware/adware. So, scan with it and then remove what is found. Once removed, uninstall MalwareBytes for Mac. Then restart the Mac.

Downloads:

1. Malwarebytes Anti-Malware for Mac
2. Malwarebytes Uninstaller

D. Clean: Space:

Delete: Unneeded, Large Files:

Remove all unneeded files from your TV and Music Libraries. Full-Movies take up 2-4GB typically, and a bunch of those would take up a load of storage, ideally. So, if you have any movies that are not needed, then delete them.  Virtual Machines can be in the double and triple digits of GBs of data.

E. Clear: Temporary Internet Files:

• Cookies perform remembrance of certain site-entered data.
• Cache keeps a snapshot of the last time you visited a site.

Go Here: Clear the History and Cookies from Safari on your iPhone, iPad, or iPod Touch - Apple Support

On your macOS Catalina —you can try re-installing the Safari 15 (92.5 MB Installer pkg): Safari 15

and see if it sorts your issue. The CDN's cache is invalidated periodically, so may not be a long standing link.

Very nice of you LD - but just in the interest of security, is there a link to the standalone Safari 15 installer direct from Apple's support site? I haven't been able to find one.

On the linked file posted here - “Show Package Contents” option isn’t available - and drilling down in Terminal could be a project if there are multiple levels of nested packages! Not to say anything nefarious is in there but I'm just a couple extra levels of cautious these days. Please no offense.

This is Apple's own swCDN (software content distribution network) as seen from the link's domain name:

swcdn.apple.com/...

reference link:

I found this on another site, works on my mid 2012 MBP:

In the Safari Menu Bar, go to Develop >> Experimental Features >> then check both WebGL 2.0 and WebGL via Metal.

If Develop is not in the Safari Menu bar, go to Safari >> Preferences >> Advanced >> and tick "Show Develop menu in menu bar" down the bottom, then go to Develop >> Experimental Features >> then check both WebGL 2.0 and WebGL via Metal

Hope this helps, sure helped me

Open Safari, go to Preferences, Select the Extensions tab, and uncheck all extensions, restart the browser and try again. That is of course if you have any extensions.

Oldekamp you're a genius. That's fixed my "A problem repeatedly occurred" in Streetview and Strava. On my Safari install WebGL 2.0 was ticked WebGL via Metal was not.

Solved the problem for me :

In the Safari Menu Bar, go to Develop >> Experimental Features >> then check WebGL via Metal.

"Safari 15 not opening websites - 'a problem repeatedly occurred': Thanks TheLittles - I'm sure ABCDE might help some, but this is not happening on just my machine - according to many people across the web today, it's happening to many/most people since the security update was pushed.[...]"

Thank you or the followup reply.

Give Apple Feedback:

Being somewhat new of an issue, I wonder if many have even reported it yet?

Do your Part: Provide Apple with feedback on this, letting them know what exactly is occurring.  Apple may not get back to you directly, but the more feedback they receive on this, the more they will know what is occurring, and what bug fixes to include in updates to come.

1. Go Here: Feedback - Safari - Apple
2. Select: "Bug Report" for the "Feedback Type"
3. Comment: on when you came across this issue, and how you have troubleshot it thus far.
4. Proceed from there as necessary

Updated to Monterey 12.1 with Safari 15.2 and when I click links in one Tab another new Tab opens my Start page and the first/intended link does not resolve. I digested this thread and went ahead and UNCHECKED the WebGL 2.0 and WebGL via Metal. Issue resolved.
