Title: Cannot run Extended (MacOS)
Post by: Lightrix on May 11, 2026, 01:41:51 AM
I run Simutrans off of Steam, and I wanted to give extended a go. However, the extended (nightly) game version crashes whenever I either fullscreen, or choose a pakset. I then tried installing the Pakset directly off the forums and adding it to the folder so it would appear in any version (image 1), but when selecting it, I'm given an error message (image 2). Could anyone help me get Simutrans extended running?

Paks for standard Simutrans do not work in Extended, and vice versa.
Only paks designed for Extended work in Extended.

Ok, so does that just mean that Extended is incompatible with MacOS? I've tried uninstalling and reinstalling but it still crashes without fail.

I don't know about MacOS

but

Your first screenshot shows the normal Simutrans with "pak128.britain-ex-nightly" this doesn't work.
The second screenshot shows Simutrans extended which is to old for the loaded pak. Maybe this is pak128.britain and not the version for extended.

Maybe you have to compile the recent Simutrans extended for MacOS yourself.

Extended has been playable on OS X/MacOS in the past, but it's been 5 years since anybody contributed code to the MacOS version, so it's very possible that something has broken during that time.

This thread (https://forum.simutrans.com/index.php/topic,15654.msg153635.html#msg153635) describes how one player self-compiled and was able to participate in online games, which confirms the game was fully working on Mac. But that was back in 2016.

This thread (https://forum.simutrans.com/index.php/topic,18531.msg203741.html#msg203741) from 2023 shows that Roboron (our Steam specialist) was hoping to make Extended playable on Mac via Steam. But he might have been relying on the GitHub Actions builds, which are currently suspended.

You could try to get it working either by learning how to compile Extended on your own Mac, or learning how GitHub Actions work so that you could get GitHub to compile it for you. Standard is built nightly (e.g. this Intel workflow (https://github.com/simutrans/simutrans/actions/runs/25691234821/workflow)) for MacOS using GitHub Actions, so you might be able to use that as a starting point. I don't know enough about Macs to say which approach would be easier.
