I was able to bypass this annoying error by doing the following.

open up the Terminal app

sudo open /Applications/Epic\ Games\ Launcher.app/Contents/MacOS/EpicGamesLauncher-Mac-Shipping

the command above will launch Epic's app (dont close the Terminal window, we gonna need it later)

try to launch Unreal

get back to the Terminal window and search for something that looks like the above

Preparing to launch app '/Users/Shared/Epic Games/UnrealTournament/Engine/Binaries/Mac/UE4-Mac-Shipping.app' with commandline 'UnrealTournament -AUTH_LOGIN=unused -AUTH_PASSWORD=foobar -AUTH_TYPE=exchangecode -epicapp=UnrealTournamentDev -epicenv=Prod -EpicPortal -epicusername="YOURUSERNAME" -epicuserid=verylongid -epiclocale=en'

open up another Terminal tab (Command + T will do it)

now you have basically tio invoke the Unreal app, with Epic's commands, like:

sudo /Users/Shared/Epic\ Games/UnrealTournament/Engine/Binaries/Mac/UE4-Mac-Shipping.app/Contents/MacOS/UE4-Mac-Shipping UnrealTournament -AUTH_LOGIN=unused -AUTH_PASSWORD=foobar -AUTH_TYPE=exchangecode -epicapp=UnrealTournamentDev -epicenv=Prod -EpicPortal -epicusername="YOURUSERNAME" -epicuserid=verylongid -epiclocale=en

P.S: You have to add "/Contents/MacOS/UE4-Mac-Shipping UnrealTournament" because its where the binary lives.

It cant find my account

[Habanero83]

same here any fix yet?

[Dragonflycreativ]

Just a heads up: I did this stuff and it couldn't find my directory /Users/Shared/Epic

So I looked and apparently the space in "Epic Games" was throwing it off. So:

/Users/Shared/Epic\ Games/UnrealTournament/Engine/Binaries/Mac/UE4-Mac-Shipping.app/Contents/MacOS/UE4-Mac-Shipping UnrealTournament ... [deleted auth info]
^------ needed to add this \ to accommodate the space in the directory structure

Cheers.

all the procedure is ok bu in the end in the terminal he ask me a password but it don't take the epic password

Hi I get an LS 00 13 error on my MAC as of a week ago. Was working fine earlier. Verified the game, re-installed, still nothing. Can anyone help? thanks

I was getting this for months. If you keep getting the LS0013, the download is corrupt.I just updated Epic Games Launcher, deleted the Unreal Tournament folder and re-downloaded the game and it now works in Mojave AND Catalina! Seems like EG dl servers are hit or miss. Especially if you dl, resume a bunch of times like I originally did, Good chance game will get corrupted.
