Fails to launch from macOS 27.0

Bug

Steam just gives an error popup with description:

Failed to start process for this game : OS Error 0

i tried reinstalling it with the option “Create an application shortcut”, but also then still failed to launch from the launcher with same error code showing on steam.

I verified the installed files from steam

version from May 14, 2026

im on a M2 macbook air

    Thank you. I originally did have the apple silicon one posted but most people told me they needed the x64 so I changed it but I guess I forgot to update the description in that one spot. You are actually the first person I am aware of trying to run it on apple silicon. I suppose I could ship both the arm64 and x64 on steam as part of the same download (it would nearly double the one time download and instillation size on disk but that’s not too much) and then just pick the right one at runtime each time. I’ll add that on my TODO list.

    I do not have a mac to test on. I know steam only gives me an option of one mac distribution either x64 or aarch64. If your mac is running apple silicon I don’t think it will work with the version on steam. You can download that version directly from https://satisfactorymodeler.itch.io/satisfactorymodeler Get both the macos-aarch64.zip and the satisfactory-modeler.zip files and extract them to the same directory.

      the itch.io version works. just fyi steam lists in the system requirements as processor apple silicon.

      i tried launching the .sh file from the steam download directly and it gives error ./satisfactory_modeler.sh: line 4: ./jdk/Contents/Home/bin/java: Bad CPU type in executable — which makes sense considering its x64.
