I updated to the latest experiemental and now when I try and launch the game I get a computer freeze, followed by a OS level crash about 10 seconds later.

the only error I have is the macOS error;

factorio-current.log is 15 minutes old and zero bytes

factorio-previous.log is ~90 minutes older and attached.

Not familiar with mac machines, but googling the error it seems this can only be caused by hardware failing.

Posted: **Tue Sep 23, 2025 6:14 pm**

I've rolled back to 2.0.67 and could launch the game, then load my save, without issues.

edit: @Loewchen just saw your last reply, all I'm doing is launching Factorio, with chrome running in the background. it might be because I have an external GPU and an intel macbook (not the modern chipset)

It's an internal cpu error, meaning the cpu itself detected that it failed and stopped execution, see here.

It’s difficult to say if this is the cause, but 2.0.68 switched away from OpenGL to Metal for graphics rendering. There’s a chance that the problem lies in there.

There is a hidden setting to force OpenGL. CTRL + ALT + Click on settings > The rest > force-opengl.

If you are willing to test this again with this hidden setting enabled, does it still cause a system crash?

Alternatively, does disconnecting the external GPU also prevent the crash?

Hi @StrangePan,

What I did was roll back to 2.0.67 and that worked. I've just upgraded to 2.0.69 and the crashes still happen. If you wanted I can try and film it and send you that video, or do some kind of screenshare?

To clarify, the crash happens when the progress bar gets to 51% when the game is launching - I never even make it to the menu to go to settings

update: rolled back to 2.0.67, toggled on the `force-opengl` setting, upgraded to 2.0.68 and it loaded the menu, exited game, upgraded to 2.0.69 and it loaded the menu.

looks like the `force-opengl` setting is necessary for my setup - an intel macbook + eGPU.

Cheers for that, I have a workaround now so it will play for me.

Interesting, so you can actually get a picture to display, but it crashes around the sprite loading phase. That gives me a place to start. I’m glad that we found a short-term fix.

If you reproduce the crash again, please send us the factorio-current.log, as it likely contains critical information.

You can enable the force-opengl option manually by editing your config file. Should be in ~/Library/Application Support/factorio/config/config.ini
https://wiki.factorio.com/Application_directory

Remove the “force-opengl=true” line, save, and restart to enable Metal. Add the line back in to revert to OpenGL again.

Also, can you send me a screenshot of your System Information > Graphics/Displays panel? I would like to see a breakdown of all your system's GPUs and the versions of Metal they do support.
