Hello Mac players! We're aware right now of two uncommon issues some players are facing. It sounds like some users on the Mojave OS are seeing a black screen, and for some players, the game crashes in the Act 4 factory. We're sorry about this! For the crash issue, there's a quick way to remedy it. Right click the game in your Steam library > Properties > BETAs tab > select "old-reliable" from the dropdown! This older version has some visual issues but no crashing. Once you're in Act 5, you can return to the original branch. We've been aware of these issues for a time, but our own Mac we were using to test didn't have these issues. As of this year, thanks to the modest success of Wandersong, I decided to get a new Mac computer (the old one was a Macbook from 2009). I'm working on setting up the new machine and will hopefully be able to test and update the game soon to fix these issues for everyone. Some of it might be an engine-level issue with Game Maker, though, which means it could take some extra time to figure out since that would be out of my hands. Mac users represent around 0.2% of all Wandersong players, but we really want you to have a good experience and I'm sorry for the issues that some of you have experienced. We'll post if and when we have an update!
