Question

Error: “MongoDB Compass.app” can’t be opened because Apple cannot check it for malicious software.

Answer 1

To run MongoDB Compass on Mac OS when encountering the "MongoDB Compass.app can't be opened because Apple cannot check it for malicious software" error, right-click on the application and choose "Open." Cancel the warning dialog, go to System Preferences > Security & Privacy, and click "Open Anyway" under the message about an unidentified developer. Confirm your action in the subsequent dialog, and MongoDB Compass should launch without further issues. Note that you should trust the source of the installation before bypassing the warning.

Answer 2

1.  Mac OS displays this warning because the compass binary is not notarised yet for Mac. 

This can be done by right-clicking on it in the application folder and selecting Open, you get a second warning with an additional button that allows you to open.

2. By moving the compass into the main Application’s section and then launching it from there, generally resolves most of the issues and the compass will work fine.
