sudo spctl --master-disable
sudo chmod -R 777 /Applications/LDPartEditor.app
xattr -d com.apple.quarantine /Applications/LDPartEditor.app
xattr -cr /Applications/LDPartEditor.app
The first command allows applications from unidentified developers
The second might be optional but will repair the application's permissions if required
The third and fourth lines will add the application to the whitelist of Gatekeeper, Apple's protection system
Hmm. OK, I'll look more into it. I had been getting an error message with the xattr commands, saying there's no such attribute as "com.apple.quarantine".
But I notice you're acting on the .app package itself, rather than the executable inside it, which might be the reason.
