If you upload a Mac version of your game on Steam, do you need to sign and notarize it, therefore, paying $99/yr to Apple?
I can't seem to find a clear answer to this. I initially thought that as long as the game is launched through Steam, there is no need to sign or notarize the game yourself. Therefore, no need to fork an additional $99 on top of the $100 you already paid to put your game on Steam.
Is this assumption true? Can anyone who recently published a Mac version on Steam chime in?
