Safari 14 on Catalina: App signature cannot be verified

Hi,

I have a Mac running on Catalina 10.15.7 that recently updated Safari to version 14.

After that I noticed that Little Snitch cannot verify app signature (Code signature: Resource or signature modified). And when I run codesign on terminal it reports as follows:

codesign --verify --verbose /Applications/Safari.app

/Applications/Safari.app: a sealed resource is missing or invalid

[+ a number of files added]

Is this normal and expected behavior? Is the app signature somehow purposefully broken with Safari 14?

Thank you for your advice.

MacBook Pro 13″, macOS 10.13

It's due to Safari's new security model and yes I experienced the same issue immediately after Safari update took place; Little Snitch had no response. I didn't trust it so rather than live with the error I chose to reinstall Mac OS and stay at the previous version of Safari until I see either party clarify that this issue has been resolved.

To follow up on this thread. I have upgraded to Big Sur version 11.0.1 and installed Little Snitch version 5.0.2 and issue is resolved. fyi - prior to upgrading make sure to check and make sure the applications you are running are compatible with Big Sur -
