If you’re installing an app on Mac OS that is not from App Store, you may likely to receive this error:
<APP-NAME> can’t be opened because it is from an unidentified developer.
To fix this issue, try these steps:
- Click on Apple logo in Menu bar.
- Then click on System Preferences.
- Moving on, then select Security & Privacy.
- Switch to General tab then, and click Open anyway.
You should be now able to open the software, with which you were getting error.
