Oxygen Not Included is not launching on Mac OS after November’s Cloud save update.
If you are unable to launch Oxygen Not Included after updating your game and encounter errors similar to these:
"Failed to start Oxygen Not Included:
OS Error 4294956486"
OR
"The application OxygenNotIncluded.app can't be opened"
Please follow these troubleshooting steps:
- Please verify the integrity of your game files to see if this resolves the issue.
- If verifying the game files does not resolve the issue, please try uninstalling, then re-installing the game.
- If the issue persists after re-installing the game, you may want to try the workaround posted by one of our players in the bug tracker. (Thanks nessumo!)
Please note, the workaround process in the link above assumes that you are familiar with how files work on Mac OS, and requires you to tinker with and delete certain game folders/files. It is IMPORTANT to make a copy of that folder and place that copy in a different location BEFORE deleting any files.
If you have tried all troubleshooting steps above and are still unable to play the game, please report your issue in the Oxygen Not Included Bug Tracker with your logs and additional information for bug reports.
