I was just wondering if it is okay for me to quiet the Epic Games Launcher on my Macbook dock when I am not using the program?
Yes it is fine. You can close it even if you have a running UE4 project.
It’s only the launcher and can open and close it any time without losing anything.
Close the launcher and continue to work on your application? The launcher does not need to remain open. Let me know if I am understanding your question correctly.
Yes, you can close it while working on an Unreal project.
PS. You don’t even need the Epic Game Launcher in the first place; you can create a shortcut and directly launch UE4 without having to go through the Epic Games Launcher.
