--- Comment #11 from Viacheslav <pritykin.a...@gmail.com> --- I forgot to mention this command I ran with the original dmg file: /usr/sbin/spctl -a -t exec -vv /Applications/kdiff3.app > /Applications/kdiff3.app: rejected". I uninstalled the original kdiff3.app (to be clear, it started working after the actions I described in the previous comment) and installed the one you provided. The new app does not have the "“kdiff3” is damaged and can’t be opened" issue and only has this issue which could be overcome from the "Privacy and Security": https://share.cleanshot.com/rrQdpqWj > "kdiff3" Not Opened > Apple could not verify "kdiff3" is free of malware that may harm your Mac or > compromise your privacy.
