As many of you know, for the past couple of weeks there has been an issue with multiplayer on Mac. The issue was not a bug in Stardew Valley’s code (there hasn’t been a Stardew Valley update since early this year, so nothing could have changed), but instead was an “authentication” issue having to do with the PC platforms (Steam & GOG). This happened because of a strange and very specific issue with a recent software update on one of those platforms. Fortunately, we were in communication with them right away, and with their help, we’ve discovered a way to resolve the issue. If you notice an update on Steam, that’s what it is. Sorry for any inconvenience this has caused.
As always, thanks for playing Stardew Valley.
