Running TwinMotion Version 2019.4.4232 (6.0.0.4232) on a MacBook Pro 2018 with MacOS 10.14.5.

It does not let me install the ArchiCAD direct link. I am prompted the following:

Cannot open «DirectLink-Archicad\_Twinmotion\_Ac19-22.pkg» because Apple cannot confirm contents free for malware.

This software needs an upgrade. Please contact the developer for more information.

Do you have any clue?  
Thanks in advance!
