Safari 15 crashes constantly Catalina 10.15.7

Also see related discussion under “ Safari update 15.0 not working with any banking websites “ in discussions.apple ( https://discussions.apple.com/thread/253161344?answerId=255948954022&login=true ).

I'm running Catalina 10.15.7 with the security update from 28 Sept , and I installed Safari 15 at the same time.

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.

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.

There have recently been many reports of new problems with Safari. It seems that the recent Safari update has issues. Word has it that Apple knows about the problems and is working on a fix. I assume that it will be released fairly soon. In the meantime, use another browser such as Firefox or Chrome and they should work for you.

I'm running Mac OS 10.15.7. safari 15 doesn't have any audio for Sirius XM radio streaming. all other video and audio works fine for any other website. Sirius XM works fine on Google Chrome. The audio settings in preferences is ok, and well as the volume setting.

seem more than just an audio problem. it doesn't know what time it is, and i have to restart each channel I choose. and then still have to select to go 'live'. but it's a minor problem as it works on Chrome. ??

my access to web sites and banks seem ok after I reinstalled Safari 15. ( I did a Safe Boot, and reset the NVRAM, but I don't think that had any effect. ?)
