I cannot open webarchive files recently created by Safari
I created two *.webarchive files today under macOS 11.6 and Safari 15.0. Although I can open older *.webarchive files with Safari, I cannot open these new ones. The error message I get is as follows:
I am not ready to upgrade the OS yet so need a resolution that will work with 11.6. This appears to me to be a bug and not a feature of gatekeeper.
