Applies To : QuarkXPress 2018 (14.2.1, 14.2 and 14.1) // MAC OS only
We have introduced "boost_interprocess" folder over Mac operating systems due to some security issues with Callas (PDF Technology used by QuarkXPress). So we don't need to delete this folder and just let it be there. In case you try to remove this folder it will be re-created after QuarkXPress re-launch.
For more Information about Callas, please refer link : https://support.quark.com/a/solutions/articles/19000080270-new-callas-pdf-print-engine/en
