Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Install and use UE4 for multiple users on OSX?

Here's the basic scenario. I'd like to install one instance of UE4 on our iMac/macOS for all users to use. I'm admin (parent), and other users are not (children).

Now when I install it (have admin privileges) it works fine. The files are also installed under /Users/Shared/... which is a good start.

Now, when non-admin users (children) start the launcher they see that it claims the Unreal Engine is not installed, and wants to download it again. Even if I allow this (by entering my admin credentials) it fails with a permissions error. Even if I manually reset group ownership and permissions to "staff" and rwx it still fails to run.

So, is there a way to get this working? It should be a simple, shared set of binaries that anyone can run once installed. Yet it seems to not work for some strange reason.

Product Version: UE 4.14

Hi MrNightOwl,

If you have the Launcher installed under Shared users, the subsequent users accounts can launch versions of the editor by double-clicking the app straight from the install directory. (They can make an alias of this to put on the desktop or doc for easy access later.)

I created a test account and was able to launch the editor successfully without having to install a second version:



Let me know if this does not resolve your issue.

This answer is no longer relevant!!

To explain. the installer creates two folders in /Users/Shared, namely, Epic Games and UnrealEngine. Launcher is the only folder in the latter. That contains an alias to /Applications/Epic Games Launcher.app.

In other words, there is NO mechanism to bypass the Epic Launcher. Consequently, if multiple users want to play this game, they either play as the same user, or have a complete duplicate of the 20GB (YES, TWENTY GIGABYTES) folder hierarchy.

In this day and age of multi-user systems, either of these approaches is appalling. And to avoid disputes between the children I'm far more inclined to remove the application in it's entirety and discourage others from installing it until Epic Games develop software that is multi-user friendly. That is, unless they are living in the 90's in the way they administer their computer--as that's the way Epic Games assume you are.

By the way, adjusting permissions so everyone has write access using standard permissions, or ACLs doesn't change the behaviour. It's a one user, or 40GB and up choice.

I found that Steve H.'s answer does work. UE4 4.19.1. The only issue is that the EPIC Games Launcher does claim that the Unreal Engine is NOT installed, even though it is. Other users can still launch the Engine, as described by Steve H, above, by finding UE4Editor buried in the Binaries directory.

When the Editor launches, it will also launch the Game Launcher, where you can start and save projects, etc, even though it still claims that the Engine is still not installed.

This does need to be addressed by EPIC; I'm not sure why they created two different dirs to store their Launcher and their Engine. This appears to be a new "feature" after version 4.14...?
