After reading these posts, I have successfully Deploy UE 4.18 on Multiple PC’s using the directions provided in :
Unreal Engine 4 - Academic Installation - A new, community-hosted Unreal Engine Wiki - Announcements - Epic Developer Community Forums
This document does not address Mac computers. Considering the PC was essentially a copy process from single to many, I am hoping there is a similar copy process for the MAC.
I have copied the 15gig folder /Users/Shared/Epic Games/UE_4.18 but I am still looking for the Manifest and VaultCache folders or their Mac counter Parts.
Any help would be appreciated
