Mac OS Catalina "Can't Be Opened Because Apple cannot Check it for Malicious Software"

This message is appearing more and more when trying to open an application on Mac OS Catalina. My understanding is that the message relates to the notarization of software. I'm going to keep this brief because I am not talking about the following common issues which clouds research into this error.

• You are attempting to run a 32 bit application.
• You are attempting to run a very old application.
• You are attempting to run an application that has not followed Apple's publishing guideline.

In the above scenarios you can attempt to get an update from the vendor. You can try going to:

System Preferences | Security & Privacy | General

Look for a 'Run Anyway' option.

I'm talking about recent application where all of the above fails. This is what you can do:

I take no responsibility if you execute software that damages your system.

Got to a command terminal prompt. Type:

sudo spctl --master-disable

Run your application

Type:

sudo spctl --master-enable.

Cheers!
