Cannot open Epic Games Launcher on M1 MacBook Air

SimonSimonson · April 29, 2021, 2:47pm

UPDATE:
Issue seems to be resolved on macOS Big Sur 11.6 and Epic Games Launcher 13.0.0

Unfortunately I am unable to open the epic games launcher and therefore cannot access the UE4 Engine / Marketplace natively.
Upon opening the app I get an error message saying “we have encountered an error that we can not recover from and must exit”. It then proceeds to show the unreal engine crash reporter.

What I’ve tried:

Contacting Epic Games Support (twice)
Open Mac-Shipping file inside .app package
Reinstalling the launcher
Clear the cache (although I did not have web cache folder for the launcher)
Open the app using the terminal
Getting very frustrated (multiple times)
Install the launcher on an external hard drive

I am on an M1 MacBook Air using MacOs BigSur 11.3 and the launcher version 12.1.7
I would really appreciate some help with this, or maybe some reports from people with M1 machines and wether or not they are able to use the epic games launcher.
Thanks!

have you found a solution?

I got a new M1 Mac Mini, installed BigSur, Xcode and Unreal Launcher. Then installed 4.26.
Everything works just fine - Getting remote build from PC working was a pain but successful in the end.
So M1 can work - Good luck man.

No, unfortunately I still cannot open the launcher. If you find anything let me know!

Knowing that it CAN work is even a bit more frustrating But ill keep trying, thanks for the reply!

I’m on intel Mac 10.15 Catalina. It used to work half a year ago but now it doesn’t

I have the same problem…

You don’t need the launcher to open UE, just find the .uproject in your files and launch it

This fixed my Problem:

Exit the Epic Games Launcher entirely by right-clicking on the tray icon and selecting Exit.
Navigate to the following directory: WINDOWS : C:\Users\username}\AppData\Local\EpicGamesLauncher\Saved\Config\Windows
MAC: /USER/{USERNAME}/Library/Preferences/Unreal Engine/EpicGamesLauncher/Mac/
Open the **Engine.ini **file in a text editor.
Edit the file to include the following:
[Launcher]
ForceNonSslCdn=false

**Note: **If the file has the above entry saying true change it to false. If you don’t see the above entry at all in the file then copy and paste it into the file.

Save the file.
Try launching the Epic Games Launcher.

I’m having the same issue on a 2019 macbook air running ventura. It worked earlier when I had Catalina but now having issues…

I have tried adding the changes to my Engine.ini file but still having issues. I have included my log files here
