Hi, thanks for making Sentinel, it's a pretty useful app, I wanted to suggest you to look into error handling and sudo permissions. When you try to act on a file that's on /Applications (And other system directories), since Sentinel lacks permission to modify files there, the operations fail but the "App was removed from quarantine / signed" message still shows, it seems there is no error handling, and it automatically assumes it was successful after running the command or call.

I know this is the case, because I run xattr "/Applications/something.app" and I can see that the quarantine attribute is still there, so in addition to the error handling, there should be a fallback that uses sudo (Getting the correct permission using Touch ID / password) so it works in more cases.

Thanks.
