Mmm, we thought this message was fixed. Thanks for the resport we will look into it. To be sure are you using the 1.1.5.1 version? Please download again the last version for mac and try again.
I'm pretty sure I'm on the latest version. I've downloaded it today with itch.io app.
I tried to download directly from the site, and it has the same problem.
I'm not sure, where can I check the version number, but I assume that it is the latest.
