Security update for Safari 14.1 Makes It Useless, any ideas?

This update renders Safari useless with constant page reloads, anyone have a solution? Apple help suggested installing the latest OS update Big Sur which is not a solution.

Have you launched Safari by holding the shift key to prevent it reloading its last application state? This would also be a good time to clear browser cache on the Develop menu, and clear all browser history. If you have any extensions loaded, I would uninstall them one at a time to see how the browser behaves on a relaunch. Also, ensure that of those extensions, that they are the most current updates.


Safari 14.1 is working just fine for me on macOS Mojave 10.14.6 and Big Sur 11.3. I purposely have no Catalina installed in the house.

Hey! Thanks for your response, Im on Catalina not Big Sur. Ive tried everything you suggested its super frustrating trying to work and then the page just starts reloading itself. I shouldn’t have to upgrade the OS because a security update has screwed up how my apps are working. I couldn’t even revert using the latest snapshot so it’s alot more than just Safari.
