We've been getting multiple reports and emails from Steam macOS users that, for some reason, their Krita isn't working because they are not properly receiving Krita's program content from Steam. This seems to be a problem that only some macOS users are having, and strangely, none of the dev team's macOS testers have been able to reproduce this issue on their systems.
But for those of you who *are* having this very annoying issue, I want to say first that I'm sorry, and also tell you that we are aware of the issue and have put a support ticket in with Steam to see if they can help us figure out what is going wrong. This is kind of a puzzling issue, but if anybody will know what's going wrong it's Valve, so I hope that we will be able to resolve this as soon as possible.
Again, I'm really sorry for those of you who have been affected by this "EmptySteamDepot" issue. You have gone out of your way to buy Krita on Steam as a means of supporting the project, with the simple promise of fast and convenient content updates in return. Please know that I will do my best to figure this problem out as soon as I can.
(If you are having any issue with Krita on Steam, please don't hesitate to let us know!)
