Game won't run after update 393231

I am having the same problem

Hello @Ant_Brooks @UwU_Garfield, welcome to the forums. For now, could you go through the steps in the following link: Klei Support Article: Oxygen Not Included Troubleshooting Guide

And if possible always add log files to your reports, shown here: Klei Support Article: Logs and Useful Information for Bug Reports

Many, many hours later, it turns out that after the last update, ONI is (apparently) no longer compatible with MacOS 10.10. Looking at the log file, the game seems to be looking for files that just don't exist in older versions of MacOS. Upgrading to 10.15 fixed the problem for me. (Yes, after five years of procrastination, it was not being able to play ONI that finally forced me to update MacOS!)

Klei -- you might want to update the Mac requirements listed on Steam (which currently lists 10.9 as the minimum). I suspect that anyone using a similarly old version of MacOS is going to have the same experience I did.
