App can't be opened because the developer can't be verified
This is macOS protecting you from unsigned software. It's not a sign the app is dangerous if you downloaded it from a trusted source. The fix is just a couple of clicks in System Settings. If the app is from a company you trust, go to System Settings → Security & Privacy and click 'Open Anyway' next to the app name.
macOS has a security feature called Gatekeeper that checks whether apps come from trusted developers before letting you run them. If an app isn't officially signed or the developer isn't in Apple's database, macOS blocks it. This is a safety feature, but if you downloaded the app from a trusted website, it's safe to override the warning and open it.

Skip — I just want a technicianCommon mistakes to avoid
- Assuming the warning means the app is dangerous. It just means it's not officially signed by Apple
- Not checking where the app came from before clicking 'Open Anyway'. Only override the warning for apps you trust
- Closing the warning dialog thinking it will go away. You need to actively click 'Open Anyway' to go ahead
Signs you need professional help
- You've clicked 'Open Anyway' but the app still won't open or shows a different error The app is from a trusted company and you're not comfortable overriding the security warning
