Hello,
I’ve exported mac standalone applications with no problem before, but am having no luck with my current project:
- I’m doing a job that involves modifying someone else’s game that was originally made for the app store.
- I have to export this game as a desktop application.
- I can run the game fine in editing mode in unity
- I can run the game fine in a browser when I export to the web player.
- When I export to standalone desktop, it makes the application, but it won’t open at all.
- I get the attached error. The icon doesn’t even make it into the dock.
What I’ve tried:
- I fiddled with all the export settings
- I’ve been trying to figure out if the project uses some plugin with I/O or something that is stripped out for web player but not for desktop?
Has anyone seen this error before? Is there a way to figure out WHY it’s not running? I don’t see any errors in the console or anything.

I’ve googled error 10810 and it seems to be a mystery to most people. Maybe it has to do with permissions?
Try running it from the shell and see if it prints any errors.

Thanks for the suggestion. I tried opening it through the console, is that what you mean? I got the same error:
Carls-iMac:smile:esktop tracikohn$ open -n ./dungeonCrawlers_app.app
LSOpenURLsWithRole() failed with error -10810 for the file /Users/tracikohn/Desktop/dungeonCrawlers_app.app.
Carls-iMac:smile:esktop tracikohn$
I also tried going inside the package contents to open the file:
Contents/MacOS/Dugeon Crawlers
It opens a separate window in console but doesn’t show any errors. Nothing happens.
Basically, the files doesn’t run to the point where an error can even
Thanks Eric,
Opening it in the console didn’t produce any errors, but between that and examining the package contents we deduced that it hard to do with the product name in player settings.
It seems to me if the product name can break a mac desktop build, Unity should warn the developer when using an illegal name? We really had no clue all what the issue was, could have been literally anything.
