Common Mistakes to Avoid
1. Incorrect Security Settings
Reason: The System Preferences are not properly configured to allow apps from unidentified developers.
Solution: Go to System Preferences > Security & Privacy > General and temporarily allow the app from the identified developer.
2. Incomplete Download or Damaged App File
Reason: The downloaded application file is corrupted or incomplete, preventing macOS from verifying its authenticity.
Solution: Re-download the application from a trusted source and verify the integrity of the downloaded file.

Solution: Temporarily disable conflicting security software or extensions, then try opening the application again.
