Symptoms:
After installing the Helper Application, MacOS reports the following error when attempting to execute the Helper connection file:
Cause:
The MacOS security settings prevent applications downloaded from unknown developers from being executed.
Solution:
To avoid this message, visit 'System Preferences' -> 'Security & Privacy' -> 'General' and select “Allow applications downloaded from: Anywhere”.
Note that the “Allow applications downloaded from: Anywhere” setting is hidden by default on later versions of MacOS, but can be activated using the following workflow:
1. Open the Terminal app from the /Applications/Utilities/ folder and then enter the following command syntax:
sudo spctl --master-disable
Hit return and authenticate with an admin password
2. Launch System Preferences -> 'Security & Privacy' -> 'General'
3. The 'Anywhere' option under 'Allow apps downloaded from:' should now be available
