I have downloaded 6gb unreal engine via Epic Games Launcher. Now, I did a fresh OSX installation but I don’t know where is my unreal.app in my Time Machine backup so I can copy, paste it and don’t need to re-download all of it.
I have found the path
In Mac the path to installation of every unreal engine stuff is***/Users/Shared/UnrealEngine/4.9/Engine/Binaries***
Somehow on my Mac it is under /Users/Shared/Epic Games/UE_4.18
